Biological Activity

Description Cobicistat is a potent and selective inhibitor of CYP3A with IC50 of 30-285 nM.
Targets
CYP3A [1]
30 nM-285 nM
In vitro
In vitro Cobicistat (GS-9350) is a potent, and selective inhibitor of human cytochrome P450 3A (CYP3A) enzymes as a pharmacoenhancer. GS-9350 inhibits CYP3A with IC50 spectrum from 30 nM to 285 nM. In contrast to ritonavir, GS-9350 is devoid of anti-HIV activity, with IC50 of > 30μM against HIV-1 protease and EC50 of > 30μM in MT-2 HIV infection assay, and is thus more suitable for use in boosting anti-HIV drugs without risking selection of potential drug-resistant HIV variants. GS-9350 shows reduced liability for drug interactions and may have potential improvements in tolerability over ritonavir. [1]
Kinase Assay Cytochrome P450 Inhibition
Inhibition of human cytochrome P450 activities is determined in duplicate in pooled human hepatic microsomal fractions following current scientific and regulatory guidelines. Reaction conditions are linear with respect to incubation time and hepatic microsomal protein concentration. Substrates are present at concentrations equal to or less than their respective Km values determined under the same reaction conditions. Metabolite and/or substrate concentrations are determined using specific, internal standard controlled HPLC MS/MS assays. For reactions monitoring metabolite formation there is less than 20% consumption of substrate during the reaction. Unless otherwise noted microsomal fraction, diluted in potassium phosphate buffer, is preincubated with substrate and inhibitor for 5 min at 37 ℃ and the reaction initiated by the addition of an NADPH generating system followed by further incubation at 37 ℃ with shaking. Enzyme-selective positive control inhibitors are tested in parallel. At appropriate times aliquots of the mixture are removed and the reaction terminated by addition to a mixture of methanol and acetonitrile containing the respective internal standard. After centrifugation aliquots of the supernatant are subjected to HPLC-MS/MS analysis.

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.
