5-MeO-NBpBrT

5-MeO-NBpBrT (5-Methoxy-N-(4-bromobenzyl)tryptamine) is a drug which acts as an antagonist for the 5-HT2A receptor, with a claimed 100x selectivity over the closely related 5-HT2C receptor. While N-benzyl substitution of psychedelic phenethylamines often results in potent 5-HT2A agonists, N-benzyl tryptamines show much lower efficacy and are either very weak partial agonists or antagonists at 5-HT2A.
