  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 $α_2-adrenergic$ receptor. The new finding has raised significant concerns about studies using NAN-190 as a specific serotonin receptor antagonist.
