Overview

Skin laxity is a natural progressive phenomenon associated with aging. Minimally invasive tightening procedures directed at subdermal tissues or directly at superficial layers of the skin have increased dramatically in the last few years. In addition, other devices targeting deeper fatty tissue may result in relative skin laxity.
In addition, many of these non-invasive/semi-invasive procedures aimed at denaturing and breaking down fatty tissue, leave residual fragments of proteins, cells and debris within the extra cellular matrix (ECM) and intracellularly. In addition, released free fatty acids can be cytotoxic to surrounding cells. These fragments may delay healing and regeneration and would benefit from an efficient recycling program in the form of autophagy and intracellular proteasome activity.
Thus, overall body shaping techniques can benefit greatly from a topical skin application that could complement the skin tightening procedures stimulating neocollagenesis and neoelastogenesis, aid in eliminating post-surgical and non-surgical fragmentation and provide relief from procedural side-effects. In addition, tightening of the relatively lax skin that remains following certain procedures, would be of great benefit.
At a microscopic level, aging skin laxity appears to be related to disorderly dysfunctional collagen and elastin, inefficient senescent fibroblasts with decreased production of collagen and elastin, and decreased glycosaminoglycans in the dermal layer.
Many of the current devices utilized for the indications described above use non-invasive radiofrequency (RF)-based technology (hot) or cryo-based technologies (cold). RF technology involves electric energy rather than photo-energy, often utilizing skin sparing techniques or insulated needles where these are utilized and thus the epidermis is largely unaffected and untargeted in these situations. Topical formulations which tighten skin would be major complementary adjuncts to such procedures enhancing the overall outcome.
Furthermore, non-invasive fat elimination devices based on ‘cold’ or ‘hot’ technologies rely on long term apoptosis of adipocytes with gradual absorption and digestion of lipid droplets and fat cellular components. These lipid fragments may consist of free fatty acids and cellular organelles, some of which may be toxic to surrounding cellular tissue. In addition, it is possible that these fragments initiate regeneration of fat in a certain proportion of patients resulting in a condition known as ‘Paradoxical adipose hyperplasia’. Promotion of accelerated digestion of these fragments is thus advantageous. Autophagy is a process of self-degradation of cellular components activated in response to cellular stress. It is important not only for balancing energy sources in development or in response to cellular stress but also for removing misfolded/aggregated proteins, damaged organelles and pathogens. The formulations described herein are useful for accelerating or enhancing the lipolysis process.
Thus a formulation of ingredients that provides for accelerated digestion of cellular fragments, stimulates elastin, collagen and glycosaminoglycan synthesis, and provides symptomatic relief from swelling and painful subcutaneous scar tissue, would be a desirable partner for non-invasive body contouring devices.

Formulations

The formulation includes components selected to provide activity in selected areas.
Stimulation of autophagy, accelerated digestion of cellular fragments, reverse cellular senescence (wake up sleeping dormant fibroblasts to produce new collagen and elastin and build ECM), thereby improving tone and texture of skin
Hexapeptide-11 is a potent stimulator of autophagy, promotes dose and time-dependent activation of proteasome, autophagy, chaperones and antioxidant responses related genes. Hydrolyzed Candida saitoana extract stimulates autophagy, favors formation of lysosomes, purified α-glucan active ingredient, detoxifies cells by removing altered cell components (oxidized proteins and peroxidized lipids) and blocks the accumulation of lipofuscin aggregates. Plantago lanceolata, also called “Plantain,” is involved in microRNAs inhibition, restarts the protein synthesis in order to prevent cellular senescence and extracellular matrix breakdown. Oleuropein is anti-inflammatory but also stimulates UPS system and autophagy digesting worn out proteins in the cells, reversing cellular senescence.
With respect to hexapeptide-11, age-related gradual accumulation or device related sudden accumulation of damaged biomolecules (including proteins) can compromise cellular homeodynamics as they result in failure of most cellular maintenance pathways. To maintain proteostasis (protein balance) cells have developed a modular, yet integrated system which ensures general proteome quality control and it is called the proteostasis network (PN). See, e.g., Sklirou A D, Ralli M, Dominguez M, Papassideri I, Skaltsounis A L, Trougakos I P. Hexapeptide-11 is a novel modulator of the proteostasis network in human diploid fibroblasts. Redox Biol 2015; 5: 205-15. This responds to conditions of proteotoxic stress by rescuing or degrading unfolded, misfolded or non-native polypeptides. Central to the PN functionality are the two main proteolytic systems namely the autophagy lysosome (ALS) and the ubiquitin-proteasome (UPS) systems. Hexapeptide-11 promotes activation of proteasome, autophagy, chaperones and antioxidant responses related genes. This stimulation of autophagy is also important in the transformation of monocytes to macrophages enabling engulfment digestion of extracellular fragments. See, e.g., Zhang Y, Morgan M J, Chen K, Choksi S, Liu Z G. Induction of autophagy is essential for monocyte-macrophage differentiation. Blood 2012; 119(12): 2895-905. Moreover, it confers significant cellular protection against oxidative-stress-mediated premature cellular senescence. Finally, Hexapeptide-11 was found to induce the activity of extracellular MMP 2 and it also suppressed cell migration. These findings indicate that Hexapeptide-11 is a promising anti-ageing agent and a potent inducer of cellular fragment digestion.
In some embodiments, compositions described herein comprise hexapeptide-11. In some embodiments, compositions described herein, upon administering to a skin region of interest, induces an increase in expression of AMBRA1, ATG4A, PSMB5, CASP3, ATG5, or a combination thereof in the skin region.

With respect to hydrolyzed Candida saitoana extract, in order to maintain their homeostasis, cells eliminate various accumulated and degraded components. Autophagy, which was recently discovered in skin, stands out today as a powerful mechanism, essential for detoxifying cells and guaranteeing their proper functioning, thereby limiting the senescence. This extract is a purified α-glucan active ingredient, which detoxifies cells by removing altered cell components (oxidized proteins and peroxidized lipids) that saturate them and blocks the accumulation of lipofuscin aggregates, a true marker of aging. See Product monograph: Silab 2013.
In some embodiments, formulations as described herein comprise hydrolyzed Candida saitoana extract. In some embodiments, the hydrolyzed Candida saitoana extract is provided at least or about 0.05%, 0.10%, 0.25%, 0.50%, 0.75%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, 7.0%, 8%, 9%, 10%, or more than 10% by weight (wt.) In some embodiments, the hydrolyzed Candida saitoana extract is provided in a range of about to about 10%, about 0.5% to about 8%, about 0.75% to about 6%, or about 1% to about 4% by weight.

With respect to Plantago lanceolata, it inhibits micro RNA inhibition of fibroblast function, reversing cellular senescence, thus increasing collagen, laminin, elastin and decreasing MMP-1. See Kovac I, Durkac J, Holly M, et al. Plantago lanceolata L. water extract induces transition of fibroblasts into myofibroblasts and increases tensile strength of healing skin wounds. J Pharm Pharmacol 2015; 67(1): 117-25, and Debacker A, Lavaissiere L, Ringenbach C, Mondon P, Dal Toso R. Controlling MicroRNAs to Fight Skin Senescence. Cosmetics & Toiletries 2016; Feb. 4, 2016: 1-6. Small endogenous noncoding RNAs named microRNA (miRNA) bind to partially complementary sequences of their target messenger RNA (mRNA) and repress or degrade the mRNA, which cause gene inactivation or gene silencing. It appears that collagen I, Collagen IV and elastin are partially controlled by several microRNAs, and when these microRNAs are limited, it helps to boost collagen and elastin synthesis to improve the quality of the dermis. Plantago lanceolata extract was found to reduce the levels of expression of miRNAs controlling the synthesis of collagens and elastin increasing their production and reducing the fibroblast progression toward senescence. Additional in vivo studies demonstrated increased viscoelastic properties with increases in firmness of 30.9% and elasticity of 22.6%, after one month of product application (p<0.01) to the skin.
In some embodiments, formulations as described herein comprise Plantago lanceolata. In some embodiments, the Plantago lanceolata is provided at least or about 0.05%, 0.10%, 0.25%, 0.75%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, 7.0%, 8%, 9%, 10%, or more than 10% by weight (wt.) In some embodiments, the Plantago lanceolata is provided in a range of about 0.25% to about 10%, about 0.5% to about 8%, about to about 6%, or about 1% to about 4% by weight. In some embodiments, the Plantago lanceolata is provided at about 2.0% by weight.
With respect to oleuropein, it has proven anti-inflammatory effects, enhances proteasome and autophagic activities recycling used intracellular proteins and reversing cellular senescence. See Katsiki M, Chondrogianni N, Chinou I, Rivett A J, Gonos E S. The olive constituent oleuropein exhibits proteasome stimulatory properties in vitro and confers life span extension of human embryonic fibroblasts.

With respect to elastin, it is an assembly of microfibrils and tropoelastin (or soluble elastin). Elastin fibers are formed first by the synthesis of fibrillin microfibers which intertwine and then associate with tropoelastin (TE) protein molecules. TE molecules are bound together and cross linked together with fibrillin fibers by lysyl oxidase like enzyme 1 (LOXL1), a key player regulating the assembly of these two elements—this complex is then presented to the fibroblast by Fibulin 5 (FBLN5) which connects the complex to integrins that connect to the fibroblast. See Ashcroft et al., “Age-related changes in temporal and spatial distributions of fibrillin and elastin mRNAs and proteins in acute cutaneous wounds of healthy humans”, J. Pathology 1997; 183:80-9, Cenizo V, Andre' V, Reymermier C, Sommer P, Damour 0, E. P. LOXL as a target to increase the elastin content in adult skin: a dill extract induces the LOXL gene expression. Experimental Dermatology 2006; 15: 574-81, and Noblesse E, Cenizo V, Bouez C, et al. Lysyl oxidase-like and lysyl oxidase are present in the dermis and epidermis of a skin equivalent and in human skin and are associated to elastic fibers. J Invest Dermatol 2004; 122(3): 621-30.
With respect to acetyl tetrapeptide-2, it increases FBLN5 and LOXL1 protein levels, thereby increasing elastin synthesis. It also upregulates genes related to Collagen 1 synthesis. In vivo, it has shown to reduce parameters linked to skin flaccidity and dermal disorganization. See Product monograph: Uplevity™ Lipotec. June 2013.
With respect to TriHex (Palmitoyl tripeptide 1 and Palmitoyl hexapeptide 12), it clears the extracellular matrix of aggregated fragmented collagen and elastin and then stimulate increased new collagen and elastin production. See Widgerow A D, Fabi S G, Palestine R F, et al. Extracellular Matrix Modulation: Optimizing Skin Care and Rejuvenation Procedures. journal of drugs in dermatology 2016; 15(4s): S63-S71, and Widgerow A. TOPICAL SKIN RESTORATION TECHNOLOGY—ADVANCES IN AGE MANAGEMENT STRATEGIES. MODERN AESTHETICS 2016; (May/June): 1-8.
With respect to Anethum graveolens/Dill extract, it produces a reinduction of LOXL synthesis. See Cenizo V, Andre' V, Reymermier C, Sommer P, Damour O, E. P. LOXL as a target to increase the elastin content in adult skin: a dill extract induces the LOXL gene expression. Experimental Dermatology 2006; 15: 574-81. While microfibrils and soluble elastin continue to be synthesized throughout life, LOXL dramatically decreases from the age of 18. Increased levels of LOXL in the skin causes the assembly of microfibrils and tropoelastin, leading to improved mechanical properties of the skin. Elastogenesis mainly occurs until the end of the second decade of the life, although the global content of skin elastin can increase after that, the nature of this elastin protein is often suboptimal and dysfunctional. After this period, the elastin gene and fibrillin-1 gene are still active throughout the life although elastogenesis becomes low or inefficient. Therefore, elastin and fibrillin-1 themselves are not really the missing targets to reinduce elastogenesis but LOXL, which declines after the first decades of life, has been shown to stimulate elastogenesis and maintain elastic fibers homeostasis. See Liu X, Zhao Y, Gao J, et al. Elastic fiber homeostasis requires lysyl oxidase-like 1 protein. Nat Genet 2004; 36(2): 178-82. Dill extract was shown to increase the expression of LOXL in fibroblasts and in the skin engineering models and to de novo elastogenesis in vivo.

In some embodiments, the dill extract is provided in a range of about 0.25% to about 10%, about 0.025% to about 4%, about 0.5% to about 8%, about 0.75% to about 6%, or about 1% to about 4% by weight. In some embodiments, the dill extract is provided at about 1.0% by weight.
With respect to unroasted shea butter extract and avocado seed extract, they are entrapped in an active multi-lamellar mineral clay (bentonite). In adipocytes, lipolysis naturally occurs to generate energy by hydrolysis of stored triglycerides into fatty acids and glycerol which are then easily released from the cells. See Russell S T, Tisdale M J. Studies on the antiobesity effect of zinc-alpha2-glycoprotein in the ob/ob mouse. Int J Obes (Loud) 2011; 35(3): 345-54. This biochemical reaction is regulated by cAMP which activates the Hormone Sensitive Lipase (HSL), the enzyme involved in the hydrolysis. Shea butter extract increases the cAMP level through a pathway acting on Zinc alpha-2-Glycoprotein (ZAG). ZAG is a protein secreted by both adipocytes and keratinocytes—it stimulates cAMP, leading to improvement in lipolysis with a caffeine-like efficacy.
Elastase is a serine protease involved in the degradation of elastin fibers which accelerates loss of dermis density and firmness. See Alkemade J, Molhuizen H, Ponec M, et al. SKALP/elafin is an inducible proteinase inhibitor in human epidermal keratinocytes. Journal of Cell Science 1994; 107: 2335-42. Avocado seed extract is able to stimulate SKALP (SKin-derived AntiLeukoProteinase), an elastase inhibitor, inhibiting elastase activity and slowing down the dermis degradation providing a firmer skin. Silanols contained in the bentonite are known to regenerate extra cellular matrix (ECM) through increased stimulation of fibroblast growth. Clinical studies have demonstrated that silanols stimulate the production of collagen and elastin fibers leading to remodeling of the dermal fiber architecture and an overall improvement of the skin surface.

The ‘skin barrier’ functions as a natural frontier between the inner organism and the environment. It is comprised mainly by the epidermis and provides a physical (lipids, corneocytes and an acidic film on the skin surface) and a biochemical barrier provided by the slightly acidic pH. This provides for cutaneous antimicrobial defense and regulates epidermal enzyme activity and expression. The interaction of transepidermal water loss (TEWL), stratum corneum hydration (SC hydration), sebum level on the skin and the skin surface pH value maintains skin barrier functionality and skin appearance. High levels of TEWL correlate with high pH, low stratum corneum hydration and reduced skin surface lipid. There seem to be differences depending on the body site, as TEWL increases significantly with ageing at the décolleté, whereas it decreases significantly at forehead and cheek. See Luebberding S, Krueger N, Kerscher M. Age-related changes in skin barrier function—quantitative evaluation of 150 female subjects. Int J Cosmet Sci 2013; 35(2): 183-90. Hydroceramide can reinforce the natural lipid barrier of dry and aging skin and also shows an ability to maintain the moisture balance of skin. In addition hydrogenated lecithin is a natural phospholipid based emulsifier that efficiently penetrates the stratum corneum while preserving skin integrity by merging with the skin and forming a second barrier layer and providing excellent hydration to the skin surface layers.

Therapeutic Uses
The formulations described herein are useful in conjunction with body shaping techniques, such as non-invasive radiofrequency (RF)-based technology (hot) or cryo-based technologies (cold). RF technology involves electric energy rather than photo-energy, often utilizing skin sparing techniques or insulated needles where these are utilized and thus the epidermis is largely unaffected and untargeted in these situations. Accordingly, topical formulations, such as those described herein, which tighten skin are complementary adjuncts to such procedures enhancing the overall outcome.

Described herein are formulations for reducing skin laxity and reducing fat. In some embodiments, formulations result in both removal of fat and tightening of laxed skin as fat is being removed. For example, hexapeptide-11 results in removal of fat and tripeptide-1 and hexapeptide-12 result in skin tightening.
In some embodiments, formulations as described herein stimulate elastin production. In some embodiments, formulations as described herein aid in elimination of lipid droplets. In some embodiments, formulations as described herein stimulate autophagy and macrophage production to accelerate digestion of fat fragments. FIG. 3 illustrates a schematic of autophagy. Autophagy facilitates very large sized fat cells and lipid droplets (much bigger than macrophages) to be digested. The process takes place by surrounding part of the fat droplet with a cell membrane part (phagophore), which then breaks down the droplet into a smaller more digestable size and further fuses with a lysosome that pours enzymes into the droplet further breaking it down into a still smaller size. This particle can now be digested by macrophages which are drawn into the area by the process.
In some embodiments, formulations as described herein increase elastin production by increasing elastin components and fibroblast function. See FIG. 4 . In some embodiments, formulations as described herein increase GAGs (Glycosaminoglycans) and Hyaluronic acid (HA).

Compositions and formulations for topical administration can include transdermal patches, ointments, lotions, creams, gels, drops, sprays, liquids, aerosols, and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be employed. In certain applications, an ointment, lotion, cream, gel or similar formulation can be provided that can be applied to the skin using the fingers. Such formulations are typically provided in a squeeze tube or bottle or a pot, or in a roll-on, wherein a ball is secured in the top of a container of the formulation, wherein the ball is permitted to roll. By rolling the ball over the skin surface, liquid in the container is transferred to the skin in a controlled manner. An alternative delivery mechanism includes a container with a perforated lid with a mechanism for advancing an extrudable formulation through the lid. In another form, a gel formulation with sufficient structural integrity to maintain its shape is provided, which is advanced up a tube and applied to the skin (e.g., in a stick form). An advantage of the stick form is that only the formulation contacts the skin in the application process, not the fingers or a portion of a container. A liquid or gel can also be placed using an applicator, e.g., a wand, a sponge, a syringe, or other suitable method.

Palmitoyl or myristoyl functionalization can be desirable in certain embodiments as it exhibits enhanced penetration when compared to other fatty acids. In some embodiments, the peptide is functionalized with a chemical group. For example, the peptide is functionalized with acetyl. Examples include acetyl tetrapeptide-2.
Some embodiments of the methods and compositions provided herein include as a first peptide glycine-histidine-lysine (GHK). GHK is a peptide sequence that is rarely found in the class of proteins in general, but is frequently found in extracellular matrix proteins. The small size of GHK permits it to approach membrane receptors far more easily than larger peptides. Further, its unique, copper-binding structure enhances copper transport into and out of cells and promotes wound healing through several different but related pathways. Due to its strong copper binding structure, GHK can be provided in the form of GHK-Cu (copper-bound GHK form).
GHK acts as an anti-inflammatory (see, e.g., Pickart, L., The human tri-peptide GHK and tissue remodeling, J. Biomater. Sci. Polymer Edn. 2008, Vol. 19, pp. 969-988, 972-973; Pickart et al., The Human Tripeptide GHK-CU in Prevention of Oxidative Stress and Degenerative Conditions of Aging: Implications for Cognitive Health, Oxid. Med. Cell Longev. 2012, Vol. 2012, pp. 1-8, 3) and an antioxidant. GHK acts to promote wound healing by suppressing the “acute phase response” that can produce both inflammation and induce scarring. This biological response prevents the invasion of bacteria, facilitates the arrival of immune cells, stems bleeding, and provides a covering for the wounded area. GHK-Cu also suppresses the acute phase response by inhibiting the production of molecules called cytokines. Cytokines are immune cell signaling molecules that attract immune cells and that trigger the production of other molecules that promote inflammation and fibrosis (leading to the creation of scar tissue). In particular, GHK suppresses the production of cytokines including tumor necrosis factor-alpha (TNFα), interleukin-1 (IL-1), interleukin-6 (IL-6), and transforming growth factor-beta-1 (TGF-β1), a few of the key drivers of inflammation and apoptotic cell death in the wound region. As TGF-β1 is an important component for the continuation of the acute phase response, GHK's suppression of TGF-β1 also acts to shorten the duration of the acute phase response once it has begun. GHK acts as an antioxidant by blocking ferritin's release of oxidizing iron, preventing further inflammation or microbial infection (as invading microbes need iron to survive).
GHK also stimulates blood vessel growth, increases collagen production, and regenerates the extracellular matrix. GHK acts as an attractant for cells vital to the regeneration of damaged tissues such as capillary cells that rebuild blood vessels. It also upregulates the production of a variety of enzymes that remove damaged proteins while also rebuilding the extracellular matrix (ECM), a key external scaffold that is important for intercellular communication and support. In particular, GHK's induces the production of messenger RNAs (mRNAs) necessary for the regeneration of the ECM, namely collagen, proteoglycans, glycosaminoglycans, chondroitin sulfate, and dermatan sulfate. GHK's induction of increased collagen production also plays a key role in enhancing skin regrowth. GHK further stimulates blood flow into damaged tissues through three processes: angiogenesis, anti-coagulation and vascular dilation. First, GHK induces angiogenesis or new blood vessel formation by increasing the production of growth factor proteins necessary for angiogenesis such as basic fibroblast growth factor (BFGF) and vascular endothelial growth factor (VEGF). Second, GHK increases blood flow to the wounded area by expanding the number of red blood cells (via growth in erythropoietin production) and by anti-coagulatory effects such as downregulating the blood clotting molecule thromboxane. Third, GHK facilitates vascular dilation through binding to the vasoconstriction protein angiotensin II, preventing angiotensin from constricting blood vessels and reducing blood flow.
GHK promotes stem cell proliferation (see, e.g., Ito et al., Is the Hair Follicle Necessary for Normal Wound Healing, J. Invest. Dermatol. 2008, Vol. 128, pp. 1059-1061, 1059). Wound healing studies have demonstrated that the addition of GHK-Cu greatly enlarged the production of hair follicles near the wound periphery in experiments with mice. Dermal hair follicles are a significant source of stem cells that are essential for dermal healing. Research into dermal hair follicles have demonstrated that hair-bearing areas tend to heal more quickly and that cells from various portions of the follicle may contribute to both dermal cell and epithelial cell replacement as well.
Thus, by decreasing inflammation, acting as an antioxidant, stimulating growth of new blood vessels, regenerating the extracellular matrix, enhancing collagen production, and by promoting stem cell proliferation, GHK can greatly enhance skin regeneration and promote wound healing.
Some embodiments of the methods and compositions provided herein include as a second peptide valine-glycine-valine-alanine-proline-glycine (VGVAPG) (SEQ ID NO: 9). VGVAPG (SEQ ID NO: 9) is a hexapeptide that is derived from the elastin protein (see, e.g., Blanchevoye et al., Interaction between the Elastin Peptide VGVAPG and Human Elastin Binding Protein, J. Biol. Chem. 2012, Vol. 288, pp. 1317-1328, 1317-1318) (“VGVAPG” disclosed as SEQ ID NO: 9). Elastin is a protein found in connective tissue (e.g. skin) that is necessary for tissues to return to their original shape and size after undergoing temporary expansion or contraction. Due to the importance of elastin in providing elasticity and resilience, elastin plays a significant role in skin cell resistance to injury and recovery from injury. The ability of skin to return to its original form after undergoing stretching or pulling relies on cross-linked elastin proteins (tropoelastin proteins in humans) that work to form “elastic fibers.” The disruption of the elastic fiber system in healing wounds has been strongly linked to the production of scar tissue (see, e.g., Rnjak-Kovacina et al., Severe Burn Injuries and the Role of Elastin in the Design of Dermal Substitutes, Tissue Eng. Part B. Rev. 2011, pp. 81-91, 85-86). Because of these properties and others, elastin is a key component in the effective wound healing process.
VGVAPG (SEQ ID NO: 9) plays a role in facilitating elastin's ability to prevent skin injury and to promote skin regeneration (see, e.g., Floquet et al., Structural Characterization of VGVAPG, an Elastin-Derived Peptide, Biopolymers (Peptide Science) 2004, Vol. 76, 266-280, 267) (“VGVAPG” disclosed as SEQ ID NO: 9). First, it has been shown to demonstrate the ability to attract monocytes and fibroblasts (see, e.g., Senior et al., Val-Gly-Val-Ala-Pro-Gly, a Repeating Peptide in Elastin, Is Chemotactic for Fibroblasts and Monocytes, J. Cell Biol. 1984, Vol. 99, pp. 870-874, 870) (“Val-Gly-Val-Ala-Pro-Gly” disclosed as SEQ ID NO: 9), monocytes being essential for fighting off infection and fibroblasts being necessary for collagen production (the most abundant protein in skin) and for the regeneration of the extracellular matrix. Second, VGVAPG (SEQ ID NO: 9) provides a binding site for elastin-binding protein, a permanent component of mature elastic fibers. Third, VGVAPG (SEQ ID NO: 9) provides a binding site for elastin and extracellular matrix degradation enzymes such as matrix metalloproteinases (MMPs), which facilitate the replacement and regeneration of elastic fibers and extracellular matrix proteins.
The tripeptide and hexapeptide work synergistically to promote skin regeneration and wound healing through the attraction of healing cells, increased production of elastin and collagen, enhanced fibroblast proliferation, antioxidant behavior (preventing the release of oxidizing iron), and inducing the regeneration of the extracellular matrix. As a result, the combination of the two peptides exhibits synergistic, superior performance well beyond that expected for either of the two peptides alone.
Tripeptides promote skin regeneration through increased collagen and elastin synthesis, blocking ferritin release of oxidized iron, attracting healing cells such as capillary cells and macrophages, and through re-establishing new blood flow to the injury site. The tripeptide functions as an anti-oxidant, stimulates collagen, elastin, and hyaluronic acid. It is formulated to penetrate stratum corneum. In the extracellular matrix (ECM), it is an anti-oxidant, attracts capillaries and macrophages, which facilitates wound healing. In the cell, it decreases inflammatory cytokines, increases collagen, elastin, dermal stem cell proliferation, and hyaluronic acid.
Hexapeptides promote skin regeneration and wound healing through the induction of elastin and collagen production, fibroblast proliferation, regeneration of the extracellular matrix, and fibroblast keratinocyte mobility. The hexapeptide is formulated to penetrate the stratum corneum, and mimics the elastin binding sequence, to stimulate elastin. It binds specifically to EBP receptors on fibroblasts and keratinocytes. The binding initiates intracellular signal transduction. Hexapeptides suitable for use include Hexapeptide-12 and Hexapeptide-11. Hexapeptide-11 has the sequence: Hex-11 (Phe-Val-Ala-Pro-Phe-Pro (FVAPFP) (SEQ ID NO: 11). Hexapeptide-12 has the sequence: VGVAPG (SEQ ID NO: 9).
In topical formulations, the tripeptide is typically present in an amount of from about 50 ppm or less to about 100, 200, 300, 400, or 500 ppm or more, e.g., 50 ppm to 150 ppm.
In topical formulations, the hexapeptide is typically present in an amount of from about 50 ppm or less to about 100, 200, 300, 400, or 500 ppm or more, e.g., 50 ppm to 150 ppm.
The peptides can advantageously be provided in a base for suitable for combining with other components of a topical formulation. The base can include one or more components such as a thickener/binding agent (e.g., pentaerythrityl tetraisostearate), an emollient/dispersing agent (e.g., caprylic/capric triglyceride), a solvent (e.g., propylene carbonate), and/or a rheology modifier/anti sett ling agent (e.g., disteardimonium hectorite).
Oleuropein
In some embodiments, polyphenols such as oleuropein may be added to the compositions. Oleuropein is a polyphenol isolated from olive leaves (see e.g. Omar S H. Oleuropein in olive and its pharmacological effects. Sci Pharm 2010; 78(2): 133-54; Al-Rimawi F, Yateem H, Afaneh I. Formulation and evaluation of a moisturizing day cream containing olive leaves extract. International Journal of Development Research 2014; 4(10): 1996-2000; Kontogianni V G, Charisiadis P, Margianni E, Lamari F N, Gerothanassis I P, Tzakos A G. Olive leaf extracts are a natural source of advanced glycation end product inhibitors. Journal of medicinal food 2013; 16(9): 817-22). Oleuropein demonstrates major anti-inflammatory effects by inhibiting lipoxygenase activity and the production of leukotriene. More particularly researchers have demonstrated that oleuropein enhances proteasome activities in vitro more effectively than other known chemical activators, possibly through conformational changes of the proteasome. In this regard, it decreases reactive oxygen species (ROS), reduces the amount of oxidized proteins through increased proteasome-mediated degradation through increased proteasome-mediated degradation and autophagic pathways, and retains proteasome function during replicative senescence. Inhibition of AGE formation via blocking sugar attachment to proteins, scavenging the reactive intermediates, or breakdown of established AGE-induced cross-links constitutes an attractive therapeutic/preventive target. Oleuropein has been demonstrated to inhibit AGE formation and breakdown AGE products through its proteasome enhancing function. When oleuropein is employed in a topical formulation, it is preferably present at from about 0.005% by weight or less to about 10.0% by weight or more, typically at from about 0.01% by weight to about 5.0% by weight, e.g., at from about 0.05% by weight to about 0.1% by weight. Oleuropein is useful in compositions for promoting healing. Oleuropein is typically not employed in antiaging compositions, in that its effects tend to be incompatible with volumizing, but it can advantageously be employed in formulations for preconditioning the skin in advance of procedures as described herein (e.g., laser resurfacing, chemical peel, etc.).
Phosphatidyl Serine
In certain embodiments, phospholipids such as phosphatidylserine (PS), a highly enriched membrane phospholipid component, may be added. Phosphatidylserine has been known to have several physiological roles, such as activating signaling enzymes and antioxidant activity (see e.g. Draelos, Z., Pugliese, P. Glycation and Skin Aging: A Review. Cosmetics & Toiletries Magazine 2011; June 2011: 1-6; Lee, S., Yang, J., Park Y., et al. Protective effect and mechanism of phosphatidylserine in UVB-induced human dermal fibroblasts. European Journal of Lipid Science and Technology 2013; 115(7): 783-90; He, M., Kubo, H., Morimoto, K., et al. Receptor for advanced glycation end products binds to phosphatidylserine and assists in the clearance of apoptotic cells. EMBO reports 2011; 12(4): 358-64). It has been found to decrease MMP-1 in a dose dependent manner, to increase procollagen formation and may act as a substrate for AGE targets thus reducing the damage from glycation effects. Clearance of apoptotic cells is necessary for tissue development, homeostasis, and resolution of inflammation. Phosphatidylserine provides an “eat me” signal on the cell surface, and phagocytes recognize the signal using specific receptors such as the receptor of advanced glycation end-products (RAGE). This then binds to PS and assists in the clearance of apoptotic cells and end products of AGE. When phosphatidylserine is employed in a topical formulation, it is preferably present at from about 0.005% by weight or less to about 10.0% by weight or more, typically at from about 0.01% by weight to about 5.0% by weight, e.g., at from about 0.05% by weight to about 0.1% by weight.
Phosphatidylserine can advantageously be employed in formulations for preconditioning the skin in advance of procedures as described herein.

Carrier Systems

Liquids and gels containing the peptides and other components as described herein can be prepared using techniques as are known in the art of cosmetics manufacture. See, e.g., Handbook of Cosmetic Science and Technology, Fourth Edition, edited by André O. Barel, Marc Paye, Howard I. Maibach, CRC Press, 2014, the contents of which is hereby incorporated by reference in its entirety. Various formulations are possible. As an example, a clear cosmetic gel stick composition can include 60 to about 90% of an aliphatic polyhydric alcohol (e.g., a C2-6 alcohol containing from 2 to 6 hydroxyl groups); 1-10% of a soap; and 1-10% of a water-soluble emollient, e.g., a polyoxyalkylene ether of a C8-22 fatty alcohol, as the main ingredients, in combination with the peptides of the preferred embodiments. Aqueous extrudable gels are based on water-oil emulsion technologies. To minimize the amount of water introduced into an extrudable gel formula, the concentration of the active solution is adjusted. Ideally, a high concentration active solution (45-50%) of the peptides can be employed. Carrier systems for AP solids are typically based on volatile cyclic siloxanes because they evaporate quickly and do not leave residue on the skin. As an alternative to volatile cyclic siloxanes, alternatives can be used, including isohexadecane or C13-15 isoalkane. Solidification systems are employed to develop solid sticks that do not melt under typical storage or consumer conditions but provide an elegant skin feel and allow for easy transfer. A combination of cyclopentasiloxane and stearyl alcohol with varying degrees of additional waxes such as hydrogenated castor wax, hydrogenated vegetable oils and polyethylene, can be employed.
For liquid formulations (e.g., gel or lotion forms), a silicone, e.g., a cyclosiloxane or linear silicone (e.g., silicone elastomer), can be employed as a carrier. One type of suitable carrier is a dimethicone crosspolymer gel, e.g., dimethicone crosspolymer in cyclopentasiloxane. Other suitable dimethicone crosspolymers include cyclopentasiloxane, dimethicone/vinyldimethicone crosspolymer; dimethicone, dimethicone/vinyl dimethicone crosspolymer; and isodecane dimethicone/vinyl dimethicone crosspolymer.
Typically, the carrier is present in an amount of from about 80 wt. % to about 95 wt. %, or 82 wt. % to 92 wt. %, e.g., in a topical formulation for application to skin or mucous membranes.

Other Components

Penetration Enhancers
Fatty acids and alcohols can be employed to enhance penetration of the peptides, and to provide a silky feel to formulations, e.g., methanoic acid, ethanoic acid, propanoic acid, butanoic acid, isobutyric acid, pentanoic acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, myristoleic acid, isovaleric acid, palmitoleic acid, sapienic acid, oleic acid, elaidic acid, vaccenic acid, linoleic acid, linoelaidic acid, α-linolenic acid, arachidonic acid, eicosapentaenoic acid, erucic acid, docosahexaenoic acid, caprylic acid, capric acid, lauric acid, palmitic acid, stearic acid, arachidic acid, behenic acid, lignoceric acid, cerotic acid, medium chain fatty acids, e.g., C6-12 fatty acids, or the like. Typical amounts when employed in topical formulations are from 1% by weight to 4% by weight. Other components can include anti-inflammatory agents, antioxidants, and solubility enhancers. For example, certain components of the formulation tend to be difficult to solubilize in conventional formulations. Phosphatidyl serine and oleuropein are known to exhibit solubility issues. In some embodiments, a siloxane polymer, e.g., caprylyl methicone, is used to solubilize phosphatidylserine. In some embodiments, caprylyl methicone is used to solubilize phosphatidylserine in anhydrous formulations. In some embodiments, panthenyl triacetate and naringenin is used to solubilize oleuropein. For topical compositions containing from about 0.05% by weight to about 0.1% by weight phosphatidyl serine and/or from about 0.05% by weight to about 0.1% by weight oleuropein, caprylyl methicone in an amount of from about 0.5% by weight to about 1% by weight of caprylyl methicone can solubilize phosphatidylserine in an anhydrous formulation.
Bentonite clays can be employed in conjunction with the peptides to provide impart penetration and adsorption properties to the compositions, and can aid in stabilizing emulsions. Other clays, such as hectorite and magnesium aluminum silicate can also be employed. Bentonite or other clays can be modified to yield an organic modified clay compound. Salts (e.g., quaternary ammonium salts) of fatty acids (e.g., hydrogenated fatty acids) can be reacted with hectorite or other clays. As provided herein, fatty acids are referred to and described using conventional nomenclature as is employed by one of skill in the art. A saturated fatty acid includes no carbon-carbon double bonds. An unsaturated fatty acid includes at least one carbon-carbon double bond. A monounsaturated fatty acid includes only one carbon-carbon double bond. A polyunsaturated fatty acid includes two or more carbon-carbon double bonds. Double bonds in fatty acids are generally cis; however, trans double bonds are also possible. The position of double bonds can be indicated by Δn, where n indicates the lower numbered carbon of each pair of double-bonded carbon atoms. A shorthand notation specifying total #carbons:#double bonds, Δ_{double bond positrons}can be employed. For example, 20:4Δ_5,8,11,14refers to a fatty acid having 20 carbon atoms and four double bonds, with the double bonds situated between the 5 and 6 carbon atom, the 8 and 9 carbon atom, the 11 and 12 carbon atom, and the 14 and 15 carbon atom, with carbon atom 1 being the carbon of the carboxylic acid group. Stearate (octadecanoate) is a saturated fatty acid. Oleate (cis-Δ9-octadecenoate) is a monounsaturated fatty acid, linolenate (all-cis-Δ9,12,15-octadecatrienoate) is a polyunsaturated fatty acid. Fatty acids suitable for use can comprise from 5 to 30 carbon atoms, e.g., 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 carbon atoms. The fatty acid can be fully saturated, or can include as many double bonds as are feasible for the chain length. Fatty acids suitable for functionalizing hectorite or other clays include palmitic acid and stearic acid. Dialkyl quaternary cationic modifiers include dipalmoyldimonium chloride and distearyldimonium chloride. Amidoamine quaternary cationic modifiers include palmitamidopropyltrimonium chloride cetearyl alcohol and palmitamidopropyltrimonium chloride.
In some embodiments, the peptides can be in admixture with a suitable carrier, diluent, or excipient, and can contain auxiliary substances such as wetting or emulsifying agents, pH buffering agents, gelling or viscosity enhancing additives, preservatives, scenting agents, colors, and the like, depending upon the route of administration and the preparation desired. See, e.g., “Remington: The Science and Practice of Pharmacy”, Lippincott Williams & Wilkins; 20th edition (Jun. 1, 2003) and “Remington's Pharmaceutical Sciences,” Mack Pub. Co.; 18th and 19th editions (December 1985, and June 1990, respectively). Such preparations can include complexing agents, metal ions, polymeric compounds such as polyacetic acid, polyglycolic acid, hydrogels, dextran, and the like, liposomes, microemulsions, micelles, unilamellar or multilamellar vesicles, erythrocyte ghosts or spheroblasts. Suitable lipids for liposomal formulations include, without limitation, monoglycerides, diglycerides, sulfatides, lysolecithin, phospholipids, saponin, bile acids, and the like. The presence of such additional components can influence the physical state, solubility, stability, rate of release, rate of clearance, and penetration of active ingredients.
The compositions for topical administration comprise the peptide compositions as described herein and a dermatologically acceptable vehicle. The vehicle may be aqueous or nonaqueous. The dermatologically acceptable vehicle used in the topical composition may be in the form of a lotion, a gel, an ointment, a liquid, a cream, or an emulsion. If the vehicle is an emulsion, the emulsion may have a continuous aqueous phase and a discontinuous nonaqueous or oil phase (oil-in-water emulsion), or a continuous nonaqueous or oil phase and a discontinuous aqueous phase (water-in-oil emulsion). When administered topically in liquid or gel form, a liquid carrier such as water, petroleum, oils of animal or plant origin such as peanut oil, mineral oil, soybean oil, or sesame oil, or synthetic oils can be added to the active ingredient(s). Physiological saline solution, dextrose, or other saccharide solution, or glycols such as ethylene glycol, propylene glycol, or polyethylene glycol are also suitable liquid carriers. The pharmaceutical compositions can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil, such as olive or arachis oil, a mineral oil such as liquid paraffin, or a mixture thereof. Suitable emulsifying agents include naturally-occurring gums such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan mono-oleate, and condensation products of these partial esters with ethylene oxide, such as polyoxyethylene sorbitan mono-oleate. The emulsions can also contain coloring and scenting agents.
In certain embodiments, a silicone elastomer (e.g., dimethicone crosspolymer) is employed to increase delivery and penetration of the peptides into the skin. An alternative to increasing molecular weight (as with silicone gums) or adding filler (as with silicone compounds) is to partially crosslink siloxane polymers and disperse this material in an appropriate silicone carrier fluid. The resulting dimethicone crosspolymers (also known as silicone elastomers in the personal care industry) differ from basic polydimethylsiloxane (PDMS) because of the cross-linking between the linear polymers. These materials can be employed in peptide formulations, and also offer benefits in scar treatment, periwound protection and enzyme delivery. In skin care applications, the aesthetics of silicone elastomers (including those with functional groups) and their ability to absorb various oils (e.g., with a dimethicone/vinyl dimethicone crosspolymer such as Dow Corning® 9506 Elastomer Powder) are two of the elastomer's desirable properties. Silicone elastomers have a skin feel different from any of the silicone fluids, described as “smooth”, “velvety” and “powdery”. It can be modified by controlling the amount of liquid phase in the formula, and therefore the degree of swelling. Due to their film-forming properties, dimethicone crosspolymers can be used as delivery systems for active ingredients such as the peptides described herein, or other formulation components such as oil-soluble vitamins and sunscreens. Sunscreens such as octyl methoxycinnamate can be more efficiently delivered from a formulation containing a silicone elastomer, producing a higher sun protection factor (SPF). Silicone elastomer blends can be used to enhance SPF in oil-in-water formulations containing organic sunscreens. For example, in testing conducted regarding SPF, the addition of 4% silicone elastomer blend to a suncare formulation containing organic sunscreens increased the SPF from 5.7 to 18. This property of the silicone elastomer allows the effectiveness of sunscreen agents in a formulation to be maximized while reducing the amount needed to achieve a desired SPF. As a result, formulation costs can be reduced along with potential irritation caused by sunscreen actives. Accordingly, a higher SPF can be achieved with the same amount of UV absorber, resulting in enhanced performance with no added formulation cost. Silicone elastomers can be produced from linear silicone polymers by a variety of crosslinking reactions, e.g., by a hydrosilylation reaction in which a vinyl group reacts with a silicon hydride. The general process involves linear silicone polymers with reactive sites along the polymer chain reacting with a cross-linker. The dimethicone crosspolymer can be produced either as a gel made of a suspension of elastomer particles swollen in a carrier fluid (e.g., a mixture of high molecular weight silicone elastomer in cyclopentasiloxane such as Dow Corning® 9040 Silicone Elastomer Blend), or as a spray-dried powder (a dimethicone/vinyl dimethicone crosspolymer such as Dow Corning® 9506 Elastomer Powder). The gel form having desirable attributes is cyclomethicone, but low viscosity dimethicones and organic fluids can also be used. Examples of dimethicone crosspolymers in the suspension or gel form are high molecular weight silicone elastomer (12%) in decamethylcyclopentasiloxane (e.g., Dow Corning® ST-Elastomer 10) and a mixture of high molecular weight silicone elastomer in cyclopentasiloxane (e.g., Dow Corning® 9040 Silicone Elastomer Blend), which typically have an elastomer content ranging from 10 to 20% by weight.
The pharmaceutical excipients used in the topical preparations of the peptide compositions may be selected from the group consisting of solvents, emollients and/or emulsifiers, oil bases, preservatives, antioxidants, tonicity adjusters, penetration enhancers and solubilizers, chelating agents, buffering agents, surfactants, one or more polymers, and combinations thereof.
Suitable solvents for an aqueous or hydrophilic topical formulation include water; ethyl alcohol; isopropyl alcohol; mixtures of water and ethyl and/or isopropyl alcohols; glycerin; ethylene, propylene or butylene glycols; DMSO; and mixtures thereof. Suitable solvents for hydrophobic topical formulations include mineral oils, vegetable oils, and silicone oils. If desired, the peptide compositions as described herein may be dissolved or dispersed in a hydrophobic oil phase, and the oil phase may then be emulsified in an aqueous phase comprising water, alone or in combination with lower alcohols, glycerin, and/or glycols. It is generally preferred to employ anhydrous compositions, as the presence of water can result in stinging upon administration to skin tissues subject to laser treatment, chemical peel, dermabrasion, or the like. Anhydrous formulations may also act to prevent the development of water-based irritant contact dermatitis in damaged or sensitive skin, which may produce rashes and skin irritation that may retard wound healing and improvement in skin quality. Tsai, T. F., Maibach, H. I. How irritant is water? An overview. Contact Dermatitis 41(6) (1999): 311-314 (describing contact dermatitis caused by water as an irritant). However, in certain embodiments it may be acceptable to provide water based compositions, or to permit a limited amount of water to be present. For example, water may be present, but at amounts below the threshold at which a stinging sensation when applied to damaged skin may result. Osmotic shock or osmotic stress is a sudden change in the solute concentration around a cell, causing a rapid change in the movement of water across its cell membrane. Under conditions of high concentrations of either salts, substrates or any solute in the supernatant, water is drawn out of the cells through osmosis. This also inhibits the transport of substrates and cofactors into the cell thus “shocking” the cell. Alternatively, at low concentrations of solutes, water enters the cell in large amounts, causing it to swell and either burst or undergo apoptosis. Certain of the formulations as described herein can be advantageously employed where it is desirable to minimize osmotic shock.
Viscosity of the compositions can be maintained at the selected level using a pharmaceutically acceptable thickening agent. Suitable viscosity enhancers or thickeners which may be used to prepare a viscous gel or cream with an aqueous base include sodium polyacrylate, xanthan gum, polyvinyl pyrrolidone, acrylic acid polymer, carrageenans, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, propyl cellulose, hydroxypropyl methyl cellulose, polyethoxylated polyacrylamides, polyethoxylated acrylates, and polyethoxylated alkane thiols. Methylcellulose is preferred because it is readily and economically available and is easy to work with. Other suitable thickening agents include, for example, xanthan gum, carboxymethyl cellulose, hydroxypropyl cellulose, carbomer, and the like. The preferred concentration of the thickener will depend upon the thickening agent selected. An amount is preferably used that will achieve the selected viscosity. Viscous compositions are normally prepared from solutions by the addition of such thickening agents, or by employing a base that has an acceptable level of viscosity.

Suitable emulsifiers for use in topical formulations include anionic, cationic, nonionic, and zwitterionic surfactants. Preferred ionic emulsifiers include phospholipids, such as lecithin and derivatives.
Lecithin and other phospholipids may be used to prepare liposomes containing the peptide compositions as described herein. Formation of lipid vesicles occurs when phospholipids such as lecithin are placed in water and consequently form one bilayer or a series of bilayers, each separated by water molecules, once enough energy is supplied. Liposomes can be created by sonicating phospholipids in water. Low shear rates create multilamellar liposomes. Continued high-shear sonication tends to form smaller unilamellar liposomes. Hydrophobic chemicals can be dissolved into the phospholipid bilayer membrane. The lipid bilayers of the liposomes deliver the peptide compositions as described herein.
In some embodiments, liposomes are used to prepare one or more peptides. In some embodiments, the peptide is hexapeptide-11. In some embodiments, the peptide is functionalized with an acetyl group.
In some embodiments, the liposomes comprise propanediol, lecithin, or a combination thereof.

In some embodiments, the propanediol and lecithin are provided at about 0.90% by weight.
The topical formulation may contain micelles, or an aggregate of surfactant molecules dispersed in an aqueous solution. Micelles may be prepared by dispersing an oil solvent in an aqueous solution comprising a surfactant, where the surfactant concentration exceeds the critical micelle concentration. The resulting formulation contains micelles, i.e., spherical oil droplets surrounded by a membrane of polar surfactant molecules, dispersed in the aqueous solvent.
Sterols including, for example, cholesterol and cholesterol fatty acid esters; amides such as fatty acid amides, ethoxylated fatty acid amides, and fatty acid alkanolamides may also be used as emollients and/or penetration enhancers.
A pharmaceutically acceptable preservative can be employed to increase the shelf life of the composition. Other suitable preservatives and/or antioxidants for use in topical formulations include benzalkonium chloride, benzyl alcohol, phenol, urea, parabens, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), tocopherol, thimerosal, chlorobutanol, or the like, and mixtures thereof, can be employed. If a preservative, such as an antioxidant, is employed, the concentration is typically from about 0.02% to about 2% based on the total weight of the composition, although larger or smaller amounts can be desirable depending upon the agent selected. Reducing agents, as described herein, can be advantageously used to maintain good shelf life of the formulation. It is generally observed that the anhydrous formulations of the embodiments exhibit satisfactory stability, such that a preservative can be omitted from the formulation.
Suitable chelating agents for use in topical formulations include ethylene diamine tetraacetic acid, alkali metal salts thereof alkaline earth metal salts thereof, ammonium salts thereof, and tetraalkyl ammonium salts thereof.
The carrier preferably has a pH of between about 4.0 and 10.0, more preferably between about 6.8 and about 7.8. The pH may be controlled using buffer solutions or other pH modifying agents. Suitable pH modifying agents include phosphoric acid and/or phosphate salts, citric acid and/or citrate salts, hydroxide salts (i.e., calcium hydroxide, sodium hydroxide, potassium hydroxide) and amines, such as triethanolamine. Suitable buffer solutions include a buffer comprising a solution of monopotassium phosphate and dipotassium phosphate, maintaining a pH of between 5.8 and 8; and a buffer comprising a solution of monosodium phosphate and disodium phosphate, maintaining a pH of between 6 and 7.5. Other buffers include citric acid/sodium citrate, and dibasic sodium phosphate/citric acid. The peptide compositions of the embodiments are preferably isotonic with the blood or other body fluid of the recipient. The isotonicity of the compositions can be attained using sodium tartrate, propylene glycol or other inorganic or organic solutes. Sodium chloride is particularly preferred. Buffering agents can be employed, such as acetic acid and salts, citric acid and salts, boric acid and salts, and phosphoric acid and salts. It can be desirable to include a reducing agent in the formulation, such as vitamin C, vitamin E, or other reducing agents as are known in the pharmaceutical arts.
Surfactants can also be employed as excipients, for example, anionic detergents such as sodium lauryl sulfate, dioctyl sodium sulfosuccinate and dioctyl sodium sulfonate, cationic such as benzalkonium chloride or benzethonium chloride, or nonionic detergents such as polyoxyethylene hydrogenated castor oil, glycerol monostearate, polysorbates, sucrose fatty acid ester, methyl cellulose, or carboxymethyl cellulose.

Suspensions can be formulated according to methods well known in the art using suitable dispersing or wetting agents and suspending agents. The preparation of acceptable aqueous or nonaqueous solutions with suitable properties, e.g., pH, isotonicity, stability, and the like, is within the skill in the art. For example, an isotonic vehicle such as 1,3-butanediol, water, isotonic sodium chloride solution, Ringer's solution, dextrose solution, dextrose and sodium chloride solution, lactated Ringer's solution, or other vehicles as are known in the art can be employed, or a fixed oil can be employed conventionally as a solvent or suspending medium, e.g., synthetic mono or diglycerides, fatty acids, or the like. The peptide formulations can also contain stabilizers, preservatives, buffers, antioxidants, or other additives known to those of skill in the art.
In certain embodiments, it can be advantageous to include additional agents having pharmacological activity. Anti-infective agents include, but are not limited to, anthelmintic (mebendazole), antibiotics including aminoglycosides (gentamicin, neomycin, tobramycin), antifungal antibiotics (amphotericin b, fluconazole, griseofulvin, itraconazole, ketoconazole, nystatin, micatin, tolnaftate), cephalosporins (cefaclor, cefazolin, cefotaxime, ceftazidime, ceftriaxone, cefuroxime, cephalexin), beta-lactam antibiotics (cefotetan, meropenem), chloramphenicol, macrolides (azithromycin, clarithromycin, erythromycin), penicillins (penicillin G sodium salt, amoxicillin, ampicillin, dicloxacillin, nafcillin, piperacillin, ticarcillin), tetracyclines (doxycycline, minocycline, tetracycline), bacitracin, clindamycin, colistimethate sodium, polymyxin b sulfate, vancomycin, antivirals including acyclovir, amantadine, didanosine, efavirenz, foscarnet, ganciclovir, indinavir, lamivudine, nelfinavir, ritonavir, saquinavir, stavudine, valacyclovir, valganciclovir, zidovudine, quinolones (ciprofloxacin, levofloxacin), sulfonamides (sulfadiazine, sulfisoxazole), sulfones (dapsone), furazolidone, metronidazole, pentamidine, sulfanilamidum crystallinum, gatifloxacin, and sulfamethoxazole/trimethoprim.

Anti-inflammatory agents include but are not limited to, nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, celecoxib, choline magnesium trisalicylate, diclofenac potassium, diclofenac sodium, diflunisal, etodolac, fenoprofen, flurbiprofen, ibuprofen, indomethacin, ketoprofen, ketorolac, melenamic acid, nabumetone, naproxen, naproxen sodium, oxaprozin, piroxicam, rofecoxib, salsalate, sulindac, and tolmetin; and corticosteroids such as cortisone, hydrocortisone, methylprednisolone, prednisone, prednisolone, betamethesone, beclomethasone dipropionate, budesonide, dexamethasone sodium phosphate, flunisolide, fluticasone propionate, triamcinolone acetonide, betamethasone, fluocinonide, betamethasone dipropionate, betamethasone valerate, desonide, desoximetasone, fluocinolone, triamcinolone, clobetasol propionate, and dexamethasone.
In certain embodiments, the addition of emollients, emulsion stabilizers, moisturizers, excipients, and other compounds may be modified to enhance the sensory properties of the topical compositions, including but not limited to: skin feel (silkiness, lightness, creaminess, etc.), absorbency (required time at which product loses wet feel and is no longer perceived on skin), consistency, firmness, spreadability (e.g. viscosity, flow onset, shear rates), stickiness, integrity of shape, glossiness, hydrophilicity or hydrophobicity, and others. Preferably, compositions will have high spreadability and low viscosity properties. Compositions with such properties have been demonstrated to have an enhanced “silky” or “light” skin feel rating (see e.g. Bekker, M. Webber, G., Louw, N. Relating rheological measurements to primary and secondary skin feeling when mineral-based and Fischer-Tropsch wax-based cosmetic emulsions and jellies are applied to the skin, International Journal of Cosmetic Science 2013, 35(4), pp. 354-61).

Stability Testing

Stability testing of the topical formulations can be conducted as follows.
High temperature testing is now commonly used as a predictor of long-term stability. High temperature testing can be conducted at 37° C. (98 F) and 45° C. (113° F.). If a product is stored at for three months (and exhibits acceptable stability) then it should be stable at room temperature for two years. A good control temperature is 4° C. (39° F.) where most products will exhibit excellent stability. Sometime, the product is also subjected to −10° C. (14° F.) for three months.
In some embodiments, the product pass three cycles of temperature testing from −10° C. (14° F.) to 25° C. (77° F.). The product is placed at −10° C. for 24 hours and place it at room temperature (25° C.) for 24 hours. This completes one cycle. If the product passes three cycles then you can have a good degree of confidence in the stability of the product. An even more rigorous test is a −10° C. to 45° C. five-cycle test. This puts emulsions under a tremendous stress and, if it passes the test, indicates that you have a highly stable product.
The dispersed phase (of an oil-in-water emulsion) has a tendency to separate and rise to the top of the emulsion forming a layer of oil droplets. This phenomenon is called creaming. Creaming is one of the first signs of impending emulsion instability. A test method to predict creaming is centrifugation. Heat the emulsion to 50° C. (122° F.) and centrifuge it for thirty minutes at 3000 rpm. Then inspect the resultant product for signs of creaming.
Both formulas and packaging can be sensitive to the UV radiation. The product is placed in glass and the actual package in a light box that has a broad-spectrum output. Another glass jar completely covered with aluminum foil serves as a control. Discoloration of the product may be observed.
For all the above mentioned tests the color, odor/fragrance, viscosity, pH value, and, if available, particle size uniformity and/or particle agglomeration under the microscope can be observed.

Example 2: Coolsculpting Procedure

A patient underwent a Coolsculpting procedure on both sides of her abdomen. Immediately following the procedure, she applied the composition of Formula 1 to the left side abdomen only. Following the procedure, she continued to apply the composition of Formula 1 twice a day, morning and evening, to the same left side abdomen area. At four weeks, she started to observe that the loose skin on the lower left side abdomen was less noticeable and appeared more firm than that of the right side abdomen. This same observation was made through week 6 with the continued application of the composition of Formula 1 to the left side.

Example 4: Gene Expression Following Hexapeptide-11 Treatment

Gene expression in fibroblasts were measured following 72 hours of exposure to hexapeptide-11.
Dermal Fibroblasts were plated in cell culture media and allowed to grow to approximately 85-90% confluency following manufacturer's guidelines. Cells were harvested and plated at 10,000 cells per cm²in 6-well dishes cultured for 3 days. On the third day, confluency was estimated by microscopy and the cell culture media was replaced. The cells were treated with hexpapeptide-11 at a 100× concentration or control buffer without peptide. The time at initial exposure to the peptide is considered time, t=0. Treated and untreated control cells were harvested, counted and extracted for RNA at 24 hours, 48 hours, and 72 hours following t=0. Cell pellets and isolated RNA were stored at −80° C. until analysis by quantitative-PCR.
The 72-hour time point RNA samples (treated and untreated) were used for gene expression analysis. RNA was converted to first strand cDNA and analyzed by quantitative-PCR. Tables 16A-16B show the gene expression data.

Example 5: Hexapeptide-11 Treatment on Macrophage Clustering

The effects of hexapeptide-11 treatment on macrophage clustering were determined.
3T3-L1 adipocytes were untreated or treated with TNF-alpha (˜25 nM) for 24 hours. One set of TNF-alpha treated adipocytes was also treated with hexapeptide-11 (0.1 mg/mL). One set of J774 macrophages was treated with hexapeptide-11 (0.1 mg/mL) for 24 hours. The macrophages were added to the adipocytes. After an 1 hour incubation, the cells were placed on ice and incubated with a fluorescently labeled Cholera toxin B subunit to label the cell surface of macrophages a fluorescent green. The cells were then fixed with 4% formaldehyde for 15 minutes and then incubated with LipidTox to label the lipid droplets within the adipocytes a fluorescent red color. Four conditions were performed: (1) J774 macrophages with untreated adipocytes; (2) J774 macrophages with TNF-alpha treated adipocytes; (3) J774 macrophages with TNF alpha treated adipocytes plus hexapeptide-11 in the 1 hour incubation of both cell types; and (4) peptide pretreated J774 macrophages with hexapeptide-11 pretreated TNF-alpha treated adipocytes incubated together in the presence of hexapeptide-11. Images taken with a 60× objective were analyzed by counting the number of macrophages associated with ˜100 adipocytes for each condition.
FIG. 4 shows images of adipocytes and macrophages. The left panel shows free floating co-cultured adipocytes and macrophages with no TNF-alpha treatment (Control). The middle panel shows that the addition of TNF-alpha results in early adipocyte breakdown and macrophage clustering. The right panel shows that TNF-alpha and peptide treatments results in further adipocyte droplet breakdown and significant macrophage clustering.
FIG. 5A shows the number of adipocytes with either 0, 1, 2, 3, 4, and 5+ associated macrophages expressed as a percentage of the total number of adipocytes counted (˜100 adipocytes/condition). When adipocytes were untreated (white bars, first bar from the left of the group of bars 501) no adipocytes were found to have greater than 3 macrophages associated with them and the majority had no macrophages. TNF-alpha treatment greatly increased the number of macrophages associated with adipocytes (red bars, second bar from the left of the group of bars 503). Peptide treatment increased the number of macrophages associated with adipocytes (blue bars, third bard from the left of the group of bars 505), including those with cells that were pre-treated with peptide (darker blue bars, fourth bar from the left of the group of bars 507). FIGS. 5B-5C show the data as FIG. 5A with the number of macrophage/adipocyte grouped together. FIG. 5B shows adipocytes untreated (white bars, first bar from the left of the group of bars 509), TNF-alpha treatment (red bars, second bar from the left of the group of bars 511), peptide and TNF-alpha treatment (blue bars, third bar from the left of the group of bars 513), and cells pre-treated with peptide followed by TNF-alpha treatment (darker blue bars, fourth bar from the left of the group of bars 515). FIG. 5C shows adipocytes untreated (white bars, first bar from the left of the group of bars 517), TNF-alpha treatment (red bars, second bar from the left of the group of bars 519), and cells pre-treated with peptide followed by TNF-alpha treatment (blue bars, third bar from the left of the group of bars 521).
The data shows that hexapeptide-11 treatment increase macrophage clustering.

Example 6: A Double Blind Randomized Controlled Trial, Evaluating the Efficacy and Tolerability of the Regenerating Body Complex in Combination with Cryolipolysis Procedures

Ten subjects participated in the trial. Eligible subjects included women between 25 and years of age with clearly visible bilateral subcutaneous arm fat appearing as a distinct bulge of fat in the arm at least 14 cm from the elbow with soft, pliable tissue of sufficient volume for treatment on both sides. Subjects with previous fat reduction procedures or implants in or near the treatment area, previous surgery in the arms, and any contra-indication to device usage, as decided by the physician, relating to existing diseases or drug use were excluded from participating in the study. Subjects with excessive laxity were also excluded. Pregnant or lactating subjects were excluded and subjects planning on becoming pregnant during the study duration.
Subjects underwent treatment of cryolipolysis of the upper arms using the CoolSculpting System (ZELTIQ Aesthetics, Pleasanton, CA). Each subject received two −11° C., 35-minute cooling cycle to each arm delivered using the COOLPETITE Advantage™ cups. The cups were placed on two separate positions on each posterior arm (4×35-minute sessions) per the standard process. Immediately following the cessation of the treatment on each arm, a timed 3 minute (+/−1 minute) manual massage of moderate intensity was performed. The right arm received treatment first. The topical regenerating body complex product (Exemplary Formula 1M) was used to treat one arm twice a day. The comparator lotion was used to treat the other arm twice a day. Assessments on the subjects were taken at 4, 8, and 12 weeks. Study efficacy assessments included blinded investigator assessment and photography, subject satisfaction and improvement, evaluation of contour improvement over time and skin tightness, tone and texture, and evaluation of Canfield photography for quantitative assessments. Skin laxity was also measured according to the grading scale of Table 17.

TABLE 17

Skin Laxity Grading Scale

Score	Classification	Description

0	None	No loose skin, toned and firm skin with
		smooth skin surface texture
1	Mild	Mildly loose skin, somewhat toned with
		smooth skin surface texture
2	Moderate	Moderately loose skin, no deep tone, few
		wrinkles and crepiness on the skin surface
3	Severe	Very loose skin without underlying tone,
		multiple wrinkles and crepiness on skin
		surface, skin distinct from underlying
		subcutaneous tissue via palpation
4	Extreme	Prominent redundancy of skin without
		underlying tone, severe wrinkling, and
		crepiness on skin surface

FIGS. 6A-6C show images of arms following 1 month of treatment.
The data shows improvement in skin laxity following treatment.

Example 7. Improvements in Skin Laxity in the Neck

The effects of Exemplary Formula 1L as described in Table 14 were tested for improvements in skin laxity in the neck.
Exemplary Formula 1L was topically applied twice daily for 12 weeks to the auricular region of a female aged 52 years old. Biopsy Hematoxylin and Eosin (H&E) and Verhoeff-Van Gieson (VVG) stains were taken.
FIG. 7A shows a VVG stain at baseline at 10× magnification and a zoomed-in image. More clumped old elastin fibers (thin black stains) and few healthy elastin fibers (few thin black stains) were observed. FIG. 7B shows a VVG stain after 12 weeks of application of Exemplary Formula 1L at 10× magnification and a zoomed-in image. After 12 weeks, there were more thin black fibers, indicating healthier elastin fibers, and well distributed thin black fibers all over the dermis.
FIG. 7C shows an H&E stain at baseline at 20× magnification and a zoomed-in image. Flattened, more inactive basal cells were observed. FIG. 7D shows an H&E stain after 12 weeks of application of Exemplary Formula 1L at 20× magnification and a zoomed-in image. As seen in FIG. 7D, there were more layers of keratinocytes (thicker epidermis), healthier thickened cornified keratin layer (basket-weave layer) to support reduced epidermal water loss, and healthier rete ridges and basal stem cells at dermo-epidermal junction.
The data shows new, healthy and well distributed elastin fibers as well as improved epidermal health and functioning as a result of treatment of Exemplary Formula 1L.

Example 8. Improvements in Texture and Wrinkles in the Neck

The effects of a treatment regimen comprising Exemplary Formula 1L as described in Table 14 were tested.
FIGS. 8A-8B show the effects of the treatment regimen as applied to a first female subject aged 53. The treatment regimen included a gentle cleanser applied in the morning and evening, Exemplary Formula 1L applied in the morning and evening, and a broad spectrum sunscreen SPF 30 applied in the morning. As seen in FIGS. 8A-8B, there was a 44% reduction in wrinkles on the neck, 22% improvement in overall texture on the neck, and 59% improvement in red channel as compared to baseline versus the treatment regimen for sixteen weeks. FIG. 8C shows images of the female subject after 8 weeks of treatment. FIG. 8D shows images of the female subject after 12 weeks of treatment. At 12 weeks of treatment, there was a 62% reduction in redness on the neck and a 51% reduction in redness on the chest.
FIG. 9 shows the effects of the treatment regimen as applied to a second female subject aged 45. The treatment regimen included a gentle cleanser applied in the morning and evening, Exemplary Formula 1L applied in the morning and evening, and a broad spectrum sunscreen SPF 30 applied in the morning. As seen in FIG. 9 , there was a 38% reduction in the redness on the chest.
A third female subject aged 67 applied Exemplary Formula 1L twice a day. FIG. 10 shows the effects of the treatment regimen as applied to a third female subject aged 67.
The data shows that a treatment regimen comprising Exemplary Formula 1L improves the overall texture of the neck and reduces wrinkles.

Example 9: Liposome Delivery System for Hexapeptide-11

Hexapeptide-11 was formulated in a liposome for topical delivery.
A water suspension of liposomes was prepared with 300 ppm (0.03%) of hexapeptide-11 and 27% Pro-Lipo™ Neo. A schematic as seen in FIG. 11 shows the various methods for creating liposomes including hydrosoluble ingredient entrapment, liposoluble ingredient entrapment, and a Liposoluble and Hydrosoluble ingredient entrapment. Liposomes were observed following the liposome suspension process manufacturing as seen in FIG. 12 . An average particle size of the formulation comprising hexapeptide-11 encapsulated in a liposome was between about 185 nm.

Example 10: Imaging Techniques

Various imaging techniques were used to assay improvements in skin laxity as seen in FIG. 13 .

Example 11: A Second Double Blind Randomized Controlled Trial, Evaluating the Efficacy and Tolerability of the Regenerating Body Complex in Combination with Cryolipolysis Procedures

A randomized, double-blind, comparator controlled study was performed to assess the efficacy of the regenerating body complex (RBC) (Exemplary Formula 1M) compared to a bland moisturizer (Cetaphil lotion) in combination with fat reducing device cryolipolysis of the upper arm area. Five (05) subjects were randomized to receive the RBC on one arm and the comparator (Cetaphil lotion) on the other arm. Subjects had a screening, baseline/treatment visit and follow-up visits at 1, 4, 8 and 12 weeks post treatment visit. Subjects underwent cryolipolysis treatment to the upper arms on treatment visit (Day 0). Subjects were instructed to apply the blinded study cream to the assigned treatment area starting the evening of the treatment visit and twice daily throughout the entire study. Study efficacy assessments included blinded Investigator assessment and photography. Subject satisfaction and improvement were also assessed.
Study Population
Up to five (5) evaluable subjects participated in this pilot study. Eligible subjects were women between 25 and 65 years of age with clearly visible bilateral subcutaneous arm fat appearing as a distinct bulge of fat in the arm at least 14 cm from the elbow, with soft, pliable tissue of sufficient volume for treatment on both sides. Subjects with previous fat reduction procedures or implants in or near the treatment area, previous surgery in the arms, and any contra-indication to device usage, as decided by the physician, relating to existing diseases or drug use were excluded from participating in the study. Subjects with excessive laxity were also excluded. Pregnant or lactating subjects were excluded, as will subjects planning on becoming pregnant during the study duration. Subjects will be instructed to avoid starting a major diet or exercise program and maintain a constant weight (within 5% of baseline measure).
Materials and Methods
Procedure
Subjects underwent treatment of cryolipolysis of the upper arms using the CoolSculpting System (ZELTIQ Aesthetics, Pleasanton, CA). Each subject received two −11° C., 35-minute cooling cycle to each arm delivered using the COOLPETITE Advantage™ cups. The cups were placed on two separate positions on each posterior arm (4×35-minute sessions) per the site's standard process. Immediately following the cessation of the treatment on each arm, a timed 3 minute (+/−1 minute) manual massage of moderate intensity was performed. The right arm always received treatment first.
Study Topical Products
Topical products included regenerating body complex: Applied twice daily; and Comparator: Cetaphil lotion (bland OTC moisturizer). The topical products were provided in a double-blind fashion with tubes labeled A and B. Treatment assignments were blinded. Subjects were provided with one tube of Product A and one tube of Product B at the treatment visit. Additional supplies were provided if needed at future visits. Arm assignment was randomized, and subjects were instructed to apply Product A to the right upper arm and Product B to the left upper arm twice daily for the entire study duration.
Study Assessments
Photography
Standardized photography was performed at the Screening, Baseline/Treatment Visit (pre- and post-procedure), and at each of the Follow-up visits (1, 4, 8, and 12 weeks). Photos captured anterior, posterior (horizontal plane/90 degrees); and additional posterior view with the wrist at the same level of shoulder, pointing forward and elbow bent at 90 degrees. Canfield Mirror Software was used to ensure consistency in arm placement and possible analysis through ghosting and Canfield. Analysis may be performed by Canfield and/or ghosting to assess changes from baseline in tone, texture, wrinkling and total skin surface area. Other assessments may also be performed.
Investigator Assessments
The Blinded Investigator was asked to assess skin laxity at all visits and contour improvement at all follow-up visits. Assessments in skin laxity were performed by assessing the subject during the visit. Assessments in contour improvement were performed by reviewing Baseline photos compared to the study visit photos.
Subject Assessments
Subjects were asked to assess the skin laxity at all visits and improvement in the shape of their arm at all follow-up visits. Subjects completed a Global Assessment of Skin Quality at study end.
Circumference
Circumference measurements were performed at every visit and were done using one designated tape measure. They were always taken at a consistent distance from an anatomical landmark, for example, the distance from olecranon process. All measurements were done by the same investigator to avoid possible inter observer variation.
Study Visits
Subjects underwent six total visits: Screening, Treatment Visit (Day 0) and Follow-up Visits at 1, 4, 8 and 12 weeks post treatment. At the Baseline/Treatment visit, the subject was randomized to which arm will receive the regenerating body complex (RBC) or comparator. The site was provided with blinded kits. Kits were dispensed in sequential order with the lowest kit available. Subjects were instructed to apply the assigned product Labeled A to the right treatment area and product Labeled B to the left treatment area twice daily.
Standardized photos were taken at each visit. At Day 0, photos were captured pre-treatment and 15 minutes (+/−5 minutes) post procedure.
A blinded Investigator completed the Skin Laxity Assessment questionnaire (Table 18) at all study visits and the Post Procedure Contour Improvement questions (Table 19) at all follow-up visits. The Subject completed the Skin Laxity Assessment questionnaire at all study visits and the Post Procedure Improvement in their Arm Shape (Table 20) at all follow-up visits. In addition, subjects completed a Global Assessment of Skin Quality (Table 21) at the final study visit (Week 12/EOS).

Example 12. Results from Clinical Studies

Following clinical trials similar to those described Examples 6 and 11, various measurements were taken.
Arm contour and arm shape was measured in patients who underwent cryolipolysis and treated with regenerating body complex (Exemplary Formula 1M) or control. Arm contour and arm shape was measured at various patient visits including Visit 3: Week 1 Follow Up; Visit 4: Week 4 Follow Up; Visit 5: Week 8 Follow Up; and Visit 6: Week 12 Follow Up, Final Visit. Data was not used from Visit 1 (Visit 1: Screening Visit). Visit 2 is baseline/treatment. Data can be seen in FIGS. 14A-14D. As seen in FIGS. 14A-14D, efficacy was highest as Visit 5, which is 8 weeks following cryolipolysis.

Example 13: Patient Treated with Radiofrequency Followed by Regenerating Body Complex Administration

A patient underwent Vanquish ME procedure, which is a radiofrequency “hot” CoolSculpting technology. The right side of the lower abdomen below the umbilicus of the patient was administered topically regenerating body complex (Exemplary Formula 1M) following the procedure. 3D photos were taken with the QuantifiCare LifeViz® Infinity camera and software imaging system (FIGS. 15A-15C). As seen in FIGS. 15A-15C taken at week 5, 3D photos demonstrate volume and contour changes and the color scale represents volume changes in cm³. The color scale is as follows: blue color represents volume reduction, red is volume increase and yellow is neutral (no change). There was a marked reduction on the right side (arrow, FIG. 15A) and further quantified as seen in FIGS. 15B-15C. There was a 40 cm³reduction as seen in FIG. 15B and a 2 cm³reduction as seen in FIG. 15C.

The above description presents the best mode contemplated for carrying out the present disclosure, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains to make and use this disclosure. This disclosure is, however, susceptible to modifications and alternate constructions from that discussed above that are fully equivalent. Consequently, this disclosure is not limited to the particular embodiments disclosed. On the contrary, this disclosure covers all modifications and alternate constructions coming within the spirit and scope of the disclosure as generally expressed by the following claims, which particularly point out and distinctly claim the subject matter of the disclosure. While the disclosure has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive.
All references cited herein are incorporated herein by reference in their entirety. To the extent publications and patents or patent applications incorporated by reference contradict the disclosure contained in the specification, the specification is intended to supersede and/or take precedence over any such contradictory material.
Unless otherwise defined, all terms (including technical and scientific terms) are to be given their ordinary and customary meaning to a person of ordinary skill in the art, and are not to be limited to a special or customized meaning unless expressly so defined herein. It should be noted that the use of particular terminology when describing certain features or aspects of the disclosure should not be taken to imply that the terminology is being re-defined herein to be restricted to include any specific characteristics of the features or aspects of the disclosure with which that terminology is associated. Terms and phrases used in this application, and variations thereof, especially in the appended claims, unless otherwise expressly stated, should be construed as open ended as opposed to limiting. As examples of the foregoing, the term ‘including’ should be read to mean ‘including, without limitation,’ ‘including but not limited to,’ or the like; the term ‘comprising’ as used herein is synonymous with ‘including,’ ‘containing,’ or ‘characterized by,’ and is inclusive or open-ended and does not exclude additional, unrecited elements or method steps; the term ‘having’ should be interpreted as ‘having at least;’ the term ‘includes’ should be interpreted as ‘includes but is not limited to;’ the term ‘example’ is used to provide exemplary instances of the item in discussion, not an exhaustive or limiting list thereof; adjectives such as ‘known’, ‘normal’, ‘standard’, and terms of similar meaning should not be construed as limiting the item described to a given time period or to an item available as of a given time, but instead should be read to encompass known, normal, or standard technologies that may be available or known now or at any time in the future; and use of terms like ‘preferably,’ ‘preferred,’ ‘desired,’ or ‘desirable,’ and words of similar meaning should not be understood as implying that certain features are critical, essential, or even important to the structure or function of the disclosure, but instead as merely intended to highlight alternative or additional features that may or may not be utilized in a particular embodiment of the disclosure. Likewise, a group of items linked with the conjunction ‘and’ should not be read as requiring that each and every one of those items be present in the grouping, but rather should be read as ‘and/or’ unless expressly stated otherwise. Similarly, a group of items linked with the conjunction ‘or’ should not be read as requiring mutual exclusivity among that group, but rather should be read as ‘and/or’ unless expressly stated otherwise.
Where a range of values is provided, it is understood that the upper and lower limit, and each intervening value between the upper and lower limit of the range is encompassed within the embodiments.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity. The indefinite article ‘a’ or ‘an’ does not exclude a plurality. A single processor or other unit may fulfill the functions of several items recited in the claims. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage. Any reference signs in the claims should not be construed as limiting the scope.
It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases ‘at least one’ and ‘one or more’ to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles ‘a’ or ‘an’ limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases ‘one or more’ or ‘at least one’ and indefinite articles such as ‘a’ or ‘an’ (e.g., ‘a’ and/or ‘an’ should typically be interpreted to mean ‘at least one’ or ‘one or more’); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of ‘two recitations,’ without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to ‘at least one of A, B, and C, etc.’ is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., ‘a system having at least one of A, B, and C’ would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to ‘at least one of A, B, or C, etc.’ is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., ‘a system having at least one of A, B, or C’ would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase ‘A or B’ will be understood to include the possibilities of ‘A’ or ‘13’ or ‘A and B.’
All numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification are to be understood as being modified in all instances by the term ‘about.’ Accordingly, unless indicated to the contrary, the numerical parameters set forth herein are approximations that may vary depending upon the desired properties sought to be obtained. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of any claims in any application claiming priority to the present application, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
Furthermore, although the foregoing has been described in some detail by way of illustrations and examples for purposes of clarity and understanding, it is apparent to those skilled in the art that certain changes and modifications may be practiced. Therefore, the description and examples should not be construed as limiting the scope of the disclosure to the specific embodiments and examples described herein, but rather to also cover all modification and alternatives coming with the true scope and spirit of the disclosure.
