5-MeO-NBpBrT

5-MeO-NBpBrT (5-Methoxy-N-(4-bromobenzyl)tryptamine) is a N-substituted member of the methoxytryptamine family of compounds. Like other such compounds it acts as an antagonist for the 5-HT_2A receptor, with a claimed 100x selectivity over the closely related 5-HT_2C receptor.^[1] While N-benzyl substitution of psychedelic phenethylamines often results in potent 5-HT_2A agonists, it had been thought that N-benzyl tryptamines show much lower efficacy and are either very weak partial agonists or antagonists at 5-HT_2A,^[2][3] though more recent research has shown stronger agonist activity for 3-substituted benzyl derivatives.^[4] Extending the benzyl group to a substituted phenethyl can also recover agonist activity in certain cases.^[5]
