Voxilaprevir
Based on 1 Customer Validation
Voxilaprevir (GS-9857) is a noncovalent, reversible inhibitor of HCV NS3/4A protease inhibitor (PI) with pangenotypic antiviral activity. Voxilaprevir inhibits genotype 1b and 3a wild-type NS3 proteases with Ki values of 0.038 nM and 0.066 nM, respectively. Voxilaprevir is an orally active direct-acting antiviral agent (DAA) and can be used for HCV infection research.

Biological Activity
Hepatitis C virus (HCV) nonstructural protein (NS) 3/4A protease[1]
NS3/4A protease is essential for proteolytic cleavage of the HCV encoded polyprotein (intomature forms of NS3, NS4A, NS4B, NS5A and NS5B proteins) and hence for viral replication[1].In enzymatic assays using recombinant NS3 protease domains and isogenic NS4A peptide cofactors provided in trans. Voxilaprevir is against HCV genotype 1b and 3a NS3 proteases with Ki values of 0.038 nM and 0.066 nM, respectively[1].In stable cell lines (Huh-7-Lunet or Huh7-1C cells) expressing renilla luciferase-encoding HCV replicons. Voxilaprevir exhibits potent pangenotypic antiviral activity with EC50 ranging from 0.33 to 6.6 nM across genotypes 1 to 6. Voxilaprevir is against HCV replicon strain DQ314805, H77, Con1, JFH-1, J6,J8 (full length) and HM568433, SA13 (NS3 Chimera) with IC50 values of 0.33 nM, 3.9 nM, 3.3 nM, 3.7 nM, 4.5 nM, 1.8 nM, and 6.6 nM, 1.9 nM, respectively[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.
