General description

A selective 5-HT2C serotonin receptor inhibitor with lesser affinity for 5-HT2BR. Often used in conjunction with ketanserin to distinguish 5-HT2AR and 5-HT2CR activity. SB206553 has highest affinity for 5-HT2CR (Ki = 3.2nM) and less for 5-HT2BR (Ki = 5.5 nM) and 5-HT2AR (Ki = 2,300 nM).
