RS-102221 is a drug developed by Hoffmann–La Roche, which was one of the first compounds discovered that acts as a potent and selective antagonist at the serotonin 5-HT2C receptor, with around 100x selectivity over the closely related 5-HT2A and 5-HT2B receptors.[1] It has anxiolytic effects in animal studies,[2] increases the effectiveness of SSRI antidepressants,[3] and shows a complex interaction with cocaine, increasing some effects but decreasing others, reflecting a role for the 5-HT2C receptor in regulation of the dopamine signalling system in the brain.[4][5][6][7]
