BW-723C86

BW-723C86 is a tryptamine derivative drug which acts as a 5-HT2B receptor agonist. It has anxiolytic effects in animal studies, and is also used for investigating the function of the 5-HT2B receptor in a range of other tissues.

BW-723C86 is actually a mixed 5-HT2B / 5-HT2C agonist, and while it has good selectivity over 5-HT2A and other serotonin receptor subtypes, it has only around 3x selectivity for 2B over 2C and so is much less selective than most research ligands, but as of 2009 no superior 5-HT2B agonist is yet available. Highly selective 5-HT2C antagonists are available however, and so a combination of BW-723C86 with a selective 5-HT2C antagonist allows 5-HT2B mediated responses to be studied in isolation.
