Biological Activity

[Description]:

Narlaprevir is a potent, selective, orally bioavailable NS3 protease inhibitor(Ki=6 nM; EC90=40 nM)IC50 Value: 6 nM (Ki)Target: HCV NS3/4A Protease; HCVNarlaprevir (SCH 900518) is a potent inhibitor of the hepatitis C virus (HCV) nonstructural protein 3 serine protease that is primarily metabolized by the cytochrome P450-3A4 system. Narlaprevir administration resulted in a robust HCV-RNA decline and high SVR rates when followed by standard of care in both treatment-experienced and treatment-naive HCV genotype 1-infected patients.
