25I-NBOH

25I-NBOH (NBOH-2CI, Cimbi-27) is a derivative of the phenethylamine derived hallucinogen 2C-I, discovered in 2006 by a team at Purdue University. It acts as a potent agonist for the 5HT2A receptor, with a Ki of 0.12nM at the human 5HT2A receptor, making it some 5x the potency of 2C-I itself. In vitro tests showed this compound acted as an agonist but animal studies have not been reported. While the N-benzyl derivatives of 2C-I were significantly increased in potency compared to 2C-I, the N-benzyl derivatives of DOI were inactive.
