NAN-190 is a drug and research chemical widely used in scientific studies. It was previously believed to act as a selective 5-HT_1A receptor antagonist, but a subsequent discovery showed that it also potently blocks the α₂-adrenergic receptor.^[1] The new finding has raised significant concerns about studies using NAN-190 as a specific serotonin receptor antagonist.^[1]
