  • MDL 100907

Volinanserin is a potent and selective antagonist of the serotonin receptor 5-HT2A (Ki = 0.36-0.85 nM).1,2 It weakly binds 5-HT2C, α1-adrenergic, and sigma receptors (Ki = 88, 128, and 87 nM) and much less effectively associates with other serotonin, dopamine, adrenergic, muscarinic acetylcholine receptors and monoamine transporters.2,3 Volinanserin displays antipsychotic activity, attenuates impulsivity, and augments antidepressant effects in vivo.1,4,5
