    Description

    Boceprevir (EBP 520) is a potent, highly selective, orally bioavailable HCV NS3 protease inhibitor with a Ki of 14 nM in both enzyme assay and an EC90 of 350 nM in cell-based replicon assay[1][2][3][4][5]. Boceprevir inhibits SARS-CoV-2 3CLpro activity[6].

    IC50 & Target

    Ki: 14 nM (HCV NS3 protease)[1]

    In Vitro

    In the HCV NS3 protease continuous assay, Boceprevir (SCH 503034) has a potency of 14 nM (Ki) average over a large number of runs. In the 72-h bicistronic subgenomic cell-based replicon assay in HuH-7 cells, the EC50 and EC90 values are determined to be 0.20 µM and 0.35 µM, respectively. Boceprevir is also found to be a very weak inhibitor of HNE (Ki=26 µM) representing a selectivity of 2200[1].

    In Vivo

    Boceprevir, an HCV Protease Inhibitor for the Treatment of Hepatitis C Virus Infection. The pharmacokinetic profile of Boceprevir is evaluated in several animal species. Following oral administration, Boceprevir is moderately absorbed in rats (10 mg/kg), dogs (3 mg/kg), and monkeys (3 mg/kg). Absorption is relatively rapid in dogs but slower in mice (10 mg/kg), rats, and monkeys, as evidenced by mean absorption times (MAT) ranging from 0.5 to 1.4 h. The AUC is good in dogs and rats, moderate in mouse, and low in monkeys. The absolute oral bioavailability is modest in mouse, rats, and dogs (26-34%) but low in monkeys (4%)[1]. Boceprevir (100 mg/kg, orally) inhibit HCV NS3/4A protease activity in triple-transgenic mice[2].

    In Vivo:

    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: ≥ 1.67 mg/mL (3.21 mM); Clear solution

      This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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: 1.67 mg/mL (3.21 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 1.67 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Animal Administration
    [2]

    Mice[2]
    Boceprevir is purchased from MedChem Express. To evaluate the effect of Boceprevir, triple-transgenic mice are induced with Doxycycline (Dox) for 10 days (n=5 per group). On the third day after Dox induction, when plasma Gluc activity reaches its peak, the mice are administered either Boceprevir (100 mg/kg) or DMSO via oral gavage twice daily for 7 days. During this period, blood is collected from the caudal vein daily to detect plasma Gluc activity.

    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.
