RS-102221
Based on 2 publication(s) in Google Scholar
RS-102221 is a selective 5-HT2C receptor antagonist (Ki=10 nM). RS-102221 shows nearly 100-fold selectivity for the 5-HT2C receptor as compared to the 5-HT2A and 5-HT2B receptors. RS-102221 can promote the differentiation of new nerve cells. RS-102221 increases food-intake and weight-gain in rats.

RS-102221 (2 mg/kg; i.p.; single dose), combined with the 3,4-Methylenedioxy-N-methamphetamine (MDMA or 'ecstasy'), suppresses the MDMA-induced hypophagia for the first 1 h period, and also suppresses MDMA-induced hyperlocomotion in mice[3].
RS-102221 (2 mg/kg; i.p.; single dose) can reduce anxiety and reduce the amplitude of startle reflex in mice in light and dark test[4].
