Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
5-HT receptor
Dopamine receptor
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 Signaling 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.
