Org 12962

Org 12962 is a drug developed by Organon, which acts as a potent and selective agonist for the 5-HT₂ receptor family, with highest affinity at 5-HT_2C and lowest at 5-HT_2B subtypes. It was developed as a potential anti-anxiety drug, but was discontinued from human trials after tests in a public speaking challenge showed that its anti-anxiety effects were accompanied by side effects such as dizziness and a "spacey" feeling, which were attributed to poor selectivity in vivo over the hallucinogenic 5-HT_2A receptor.
