Lomibuvir (VX-222; VCH-222) is a non-cytotoxic, orally active non-nucleoside inhibitor (NNI) against hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase (genotype 1a/1b IC50 = 0.94/1.2 μM). Lomibuvir exhibits HCV genotype-selective antiviral activity in vitro (genotype 1a//1b EC50 = 23.3 nM/12 nM; ineffective against 2a & 2b) and in vivo by targeting HCV NS5B thumb II allosteric pocket, exhibiting no inhibitory potency against human DNA polymerase (α, β, γ IC50 ≥56 μM), respiratory syncytial virus, Influenza A and B, and West Nile virus.
Non-cytotoxic, orally active hepatitis C virus (HCV) NS5B RNA polymerase inhibitor with HCV genotype 1a/1b-selective antiviral activity in vitro and in vivo.
Therapeutic targeting of membrane-associated viral proteins is complicated by the challenge of investigating their enzymatic activities in the native membrane-bound state. To permit functional characterization of these proteins, we hypothesized that the supported lipid bilayer (SLB) can support in situ
The six major epidemiologically important hepatitis C virus (HCV) genotypes differ in global distribution and antiviral responses. Full-length infectious cell-culture adapted clones, the gold standard for HCV studies in vitro, are missing for genotypes 4 and 5. To address this
Hepatitis C virus (HCV) is a genetically diverse virus with multiple genotypes exhibiting remarkable differences, particularly in drug susceptibility. Drug and vaccine development will benefit from high-titer HCV cultures mimicking the complete viral life cycle, but such systems only exist
Combination therapy of directly acting antivirals (DAA's) for the treatment of chronic HCV infections has proven to be a highly effective strategy to cure chronic infections with this virus. Here we studied, using HCV as an example, how to best

Replication of the hepatitis C viral genome is catalyzed by the NS5B (nonstructural protein 5B) RNA-dependent RNA polymerase, which is a major target of antiviral drugs currently in the clinic. Prior studies established that initiation of RNA replication could be
