R1479 (4′-azidocytidine) is a specific inhibitor of hepatitis C virus (HCV) replication. 4′-azidocytidine triphosphate is an inhibitor of native HCV replicase and recombinant HCV polymerase (NS5B). Balapiravir (R1626) is the tri-isobutyrate ester prodrug of R1479 under clinical development to improve exposure of R1479 upon oral administration.

Sample Use Guides
The phase 2, double-blind international trial evaluated the optimal treatment regimen of balapiravir plus peginterferon alfa-2a (40KD)/ribavirin in hepatitis C genotype 1 patients. Treatment-naive genotype 1 patients were randomized to one of seven treatment groups in which they received balapiravir 500, 1,000, or 1,500 mg twice daily, peginterferon alfa-2a (40KD) 180 or 90 µg/week and ribavirin 1,000/1,200 mg/day or peginterferon alfa-2a (40KD)/ribavirin. The planned treatment duration with balapiravir was reduced from 24 to 12 weeks due to safety concerns.

In Vitro Use Guide
Curator's Comment: Activity is given for R1479. Balapiravir (R-1626) is the tri-isobutyl ester prodrug of a nucleoside analogue inhibitor of the hepatitis C virus (HCV) RNA-dependent RNA polymerase (R1479).
R1479 (4'-azidocytidine) is a specific inhibitor of HCV replication in the HCV subgenomic replicon system (IC(50) = 1.28 microM). R1479 showed no effect on cell viability or proliferation of HCV replicon or Huh-7 cells at concentrations up to 2 mM.

ACTIVE MOIETY |
Hepatitis C virus (HCV) polymerase activity is essential for HCV replication. Targeted screening of nucleoside analogs identified R1479 (4-azidocytidine) as a specific inhibitor of HCV replication in the HCV subgenomic replicon system (IC50 = 1.28 .MU.m) with similar potency compared with 2-C-methylcytidine (IC50 = 1.13 .MU.m). R1479 showed no effect on cell viability or proliferation of HCV replicon or Huh-7 cells at concentrations up to 2 mm.
