Description: Dasabuvir (ABT-333) is a non-nucleoside inhibitor of the hepatitis C virus (HCV) non-structural protein 5B (NS5B), an RNA-dependent RNA polymerase. Upon administration and intracellular uptake, dasabuvir binds HCV NS5B polymerase, blocking viral RNA synthesis and replication. The HCV NS5B protein is...

ABT-333 is an inhibitor of hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp, IC50s = 0.0022-0.0107 µM for genotypes 1a and 1b). It is selective for HCV genotype 1 polymerases over genotypes 2, 3, and 4 (IC50s = 0.9->20 µM), as well as human polymerases (IC50s = >100 µM). Formulations containning ABT-333,...
