Voxilaprevir

Research use only, not for human use.

Voxilaprevir (GS-9857) is a potent HCV NS3/4A protease inhibitor that is used in combination with sofosbuvir and velpatasvir for treatment of HCV infection.

Voxilaprevir (GS-9857) is a potent HCV NS3/4A protease inhibitor that is used in combination with sofosbuvir and velpatasvir for treatment of HCV infection.HCV Infection Phase 2 Clinical(In Vitro):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.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.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.
