Ziprasidone hydrochloride是 5-HT (serotonin) 和多巴胺受体(dopamine receptor) 拮抗剂。Ziprasidone hydrochloride 对大鼠 (Ki: 3.4 nM) 和人 (2.5 nM) 5-HT1A,5-HT2A (0.42 nM) 和 dopamine D2 (4.8 nM) 受体有很高的亲和力。Ziprasidone hydrochloride 是一种去甲肾上腺素再摄取 (norepinephrine reuptake) 抑制剂。
Information
Ziprasidone HCl (CP-88059) is a novel and potentdopamineandserotonin (5-HT) receptorantagonist, used in the treatment of schizophrenia and bipolar disorder.
In vitro
Ziprasidone has high affinity for human 5-HT receptors and for human dopamine D(2) receptors. Ziprasidone is a 5-HT(1A) receptor agonist and an antagonist at 5-HT(2A), 5-HT(2C) and 5-HT(1B/1D) receptors. Ziprasidone inhibits neuronal uptake of 5-HT and norepinephrine comparable to the antidepressant imipramine. Ziprasidone blocks wild-type hERG current in a voltage- and concentration-dependent manner with IC(50) of 120nM in stably transfected HEK-293 cells. Ziprasidone shows minimal tonic block of hERG current estimated during a depolarizing voltage (-20 or +30mV) or evaluated by the envelope of tails test (+30mV). Ziprasidone significantly increases the time constant of the slow component of hERG current deactivation (at -50mV).
In vivo
Ziprasidone exhibits less potent block of wild-type hERG current with IC(50) of 2.8 mM in Xenopus oocytes. Ziprasidone suppresses the significant increases in food intake produced by olanzapine, indicating that it has an intrinsic protective mechanism against drug-induced increases in food intake in rats. Ziprasidone results in a notable increase in NGF and ChAT immunoreactivity in the dentate gyrus (DG), CA1, and CA3 areas of the hippocampus of rats. Ziprasidone dose-dependently slows raphe unit activity (ED50 = 300 mg/kg i.v.) as does the atypical antipsychotics clozapine (ED50 = 250 mg/kg i.v.) and olanzapine (ED50 = 1000 mg/kg i.v.) in anesthetized rats.
