Biological Activity

Description Perphenazine (Perphenazin, Trilafon, Etaperazine) is a phenothiazine derivative and a dopamine antagonist with antiemetic and antipsychotic properties.
Targets
D1/D2 dopamine receptors [2]
In vitro
In vitro Perphenazine is a relatively high potency phenothiazine that blocks dopamine 2 (D2) receptors predominantly but also may possess antagonist actions at histamine 1 (H1) and cholinergic M1 and alpha 1 adrenergic receptors in the vomiting center leading to reduced nausea and vomiting[1]. Perphenazine induces cell death and mitochondrial damage, also caspase-3 activation and a decrease in cellular ATP level. The cell death induced by perphenazine is partially suppressed by antioxidant but not by pan-caspase inhibitor[4]. Perphenazine in concentration range from 0.0001 to 0.01 µM did not have any significant effect on melanocytes viability. The treatment of cells with the drug in higher concentrations results in the loss in cell viability in a concentration-dependent manner. The value of EC50 for perphenazine is 2.76 μM. Perphenazine in concentrations of 1.0 and 3.0 µM also decreases the tyrosinase activity, as well as melanin content[5].
Cell Research Cell lines human dopaminergic cell line, SH-SY5Y.
Concentrations 10-100 μM
Incubation Time 48 h
Method cells are plated on 96-well plates and treated with drugs for various time periods. Then the cells are incubated with MTS assay reagent for 1 hr. The plates are then read at 490 nm using a microplate reader.
In Vivo
In vivo Perphenazine is well absorbed after oral administration. The time to peak after oral administration is 1-3 hours with the time to peak of the metabolite 7-hydroxyperphenzaine 2-3 hours. Perphenazine has a half-life elimination of 9-12 hours and its metabolite 7-hydroxyperphenazine of 10-19 hours[1]. Perphenazine has been used as a psychotropic drug for several decades in therapy of certain psychiatric disorders. In rat isolated heart, perphenazine significantly prolongs the QT interval and triggers arrhythmias in considerable numbers both at the high concentration and at the therapeutical concentration. This proarrhythmogenic effect is observed even after repeated exposure to perphenazine[3].

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.
