Biochem/physiol Actions

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.

Allosteric inhibitors of hepatitis C virus (HCV) non-structural protein 5B (NS5B) polymerase are effective for treatment of genotype 1, although their mode of action and potential to inhibit other isolates and genotypes are not well established. We have used biophysical

To investigate in this phase 2a study (ZENITH) the safety, tolerability, and antiviral activity of VX-222, a selective, non-nucleoside inhibitor of hepatitis C virus (HCV) NS5B polymerase, combined with various telaprevir-based regimens for treatment of genotype 1 HCV. In total

Development of allosteric inhibitors into efficient drugs is hampered by their indirect mode-of-action and complex structure-kinetic relationships. To enable the design of efficient allosteric drugs targeting the polymerase of hepatitis C virus (NS5B), the interaction characteristics of three non-nucleoside compounds

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

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
