Introduction of 129029-23-8 :
Ocaperidone is an effective antipsychotic agent, acting as a potent 5-HT2 and dopamine D2 antagonist, and a 5-HT1A agonist, with Kis of 0.14 nM, 0.46 nM, 0.75 nM, 1.6 nM and 5.4 nM for 5-HT2, a1-adrenergic receptor, dopamine D2, histamine H1 and a2-adrenergic receptor, respectively, and a pEC50 and pKi of 7.60 and 8.08 for h5-HT1A. IC50 & Target: Ki: 0.14 nM (5HT2), 0.46 nM (a1-adrenergic receptor), 0.75 nM (Dopamine D2), 1.6 nM (Histamine H1), 5.4 nM (a2-adrenergic receptor)[1]
pEC50: 7.60 (h5-HT1A)[2]
pKi: 8.08 (h5-HT1A)[2] In Vitro: Ocaperidone has high affinify at 5-HT2 and dopamine D2, with Kis of 0.14 nM, 0.46 nM, 0.75 nM, 1.6 nM and 5.4 nM for 5HT2, a1-adrenergic, dopamine D2, histamine H1 and a2-adrenergic, respectively[1]. Ocaperidone shows 5-HT1A receptor agonist activity, with a pEC50 and pKi of 7.60 and 8.08[2]. In Vivo: Ocaperidone shows a potent occupation of 5HT2 receptor via in vivo binding in the frontal cortex of rats with an ED50 of 0.04 mg/kg, and 0.1 4-0.1 6 mg/kg for D2 receptor in the striatum and the nucleus accumbens[1]. Ocaperidone (R 79598) antagonizes dopamine D2 and 5-HT2, and shows a a partial generalization to buspirone with an ED50 of 0.163 mg/kg[3].
