Biological Activity

Antagonist of 5-HT2A and dopamine D2 receptors (Ki values are 4 and 11 nM respectively). Also displays affinity for a range of other receptors including D1 and D4, 5-HT2C, α1, H1 and M1-4 receptors (Ki values range between 1.9 and 31 nM). Atypical antipsychotic. Displays anticholinergic properties. Also a highly potent activator of hM4Di DREADDs (EC50 values are 5 nM in vitro and 7 nM in vivo).
