25CN-NBOH (or NBOH-2C-CN) is a compound indirectly derived from the phenethylamine series of hallucinogens which was discovered in 2011 by Martin Hansen at the University of Copenhagen. This compound is notable as one of the most selective agonist ligands for the 5-HT2A receptor yet discovered with a pKi of 8.88 at the human 5-HT2A receptor and with 100x selectivity for 5-HT2A over 5-HT2C and 46x selectivity for 5-HT2A over 5-HT2B.
