SB-699551

SB-699551 is a drug which was the first compound developed to act as a selective antagonist for the serotonin receptor 5-HT_5A, with selectivity of around 100x over other serotonin receptor subtypes.^[1] Multiple therapeutic roles have been suggested for 5-HT_5A ligands due to the presence of this receptor in several areas of the brain, but research is still at an early stage,^[2] In animal studies, SB-699551 was found to block cue-mediated responding to LSD, again suggesting an antipsychotic type of activity.^[3] It also reduces the viability of certain types of cancer cells in vitro, suggesting the 5-HT_5A receptor as a possible target for novel chemotherapy drugs.^[4][5]
