    製品説明

    Cobicistat is a potent and selective inhibitor of cytochrome P450 3A (CYP3A) enzymes with IC50s of 30-285 nM. Cobicistat is a pharmacokinetic enhancer which increases the overall absorption of several HIV medications.

    IC50 & Target

    CYP3

     

    HIV-1

     

    体外実験

    In HIV-1 protease enzymatic assay and antiviral cellular assays. Cobicistat is inactive against HIV-1 protease (IC50>30 μM) . And Cobicistat has no inhibitory effect against HIV replication in a multicycle 5-day MT-2 HIV infection assay (EC50>30 μM). In assays using MT-2 cells, Cobicistat exhibits minimal cytotoxicity, with a CC50 value above 80 μM[1].
    The mode of inhibition of human CYP3A by Cobicistat and Ritonavir shares the same mechanism of action for the inhibition of CYP3A. It shows its inhibitory effects on CYP3A may involve directly at the heme group of the CYP3A enzyme[1].
    The minimal adverse effects of Cobicistat in these assays suggest a lower potential for toxicity related to altered lipid metabolism.
    In the lipid accumulation assay with the human adipocytes, Ritonavir shows a clear effect with an EC50 of 16 μM. However, Cobicistat exhibits no effect at a concentration up to 30 μM[1].
    In the glucose uptake assay with mouse adipocytes, Ritonavir shows a pronounced effect at the concentration of 10 μM. In contrast, the effects on glucose uptake by Cobicistat (10 μM) is significantly less[1].

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.08 mg/mL (2.68 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.08 mg/mL (2.68 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    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°C and the reaction initiated by the addition of an NADPH generating system followed by further incubation at 37°C 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.

    Five-fold serial dilutions of the tested compounds are prepared in triplicate in 96-well plates. MT-2 cells are added to plates at a density of 20,000/well in a final assay volume of 200 μL. After a 5-day incubation at 37°C, the cytotoxic effect is determined using a cell viability assay. One hundred μL media is removed from each well and replaced with 100 μL of phosphate-buffered saline containing 1.7 mg/mL XTT and 5 μg/mL PMS. Following 1-hour incubation at 37°C, 20 μL of 2% Triton X- 100 is added to each well and absorbance is read at 450 nm with a background subtraction at 650 nm. The data are plotted as cell viability vs. drug concentration. Cell viability is expressed as a percentage of the signal from untreated samples (0% cytotoxicity) after the subtraction of signal from samples treated with 10 μM of Podophyllotoxin (100% cytotoxicity). The CC50 value is calculated from the inhibition plots as the concentration of drug which inhibits cell proliferation by 50%.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
