RH-34 is a potent and selective partial agonist for the 5-HT2A serotonin receptor subtype, developed through structural modification of the selective 5-HT2A antagonist ketanserin. This compound replaces the 4-(p-fluorobenzoyl)piperidine moiety of ketanserin with the N-(2-methoxybenzyl) pharmacophore found in potent 5-HT2A agonists like NBOMe-2C-B and NBOMe-2C-I. This alteration maintains 5-HT2A affinity and selectivity but shifts the activity from antagonism to a moderate efficacy partial agonist.
