hcv genotype 1a

Filibuvir (PF-00868554) is a selective and noncovalent inhibitor of HCV NS5B RNA-dependent RNA polymerase. Filibuvir inhibits genotype 1a and 1b replicons with EC50s of 59 nM.

Furaprofen is an orally available, selective and potent HCV inhibitor with anti-inflammatory activity, inhibits carrageenan-induced paw edema in rats and inhibits cotton pellet-induced granulomas in rats at higher doses.

Inarigivir soproxil (SB9200) is an agonist of innate immunity that demonstrates effective antiviral activity against resistant hepatitis C virus (HCV) variants, with EC50s of 2.2 and 1.0 μM for HCV 1a 1b in cells of genotype 1 HCV replicon systems.

JTK-853 is a novel, non-nucleoside inhibitor of Hepatitis C Virus (HCV) polymerase, exhibiting effective antiviral activity in HCV replicon cells with EC50s of 0.38 μM for genotype 1a H77 strain and 0.035 μM for genotype 1b Con1 strain.

Paritaprevir (ABT450) is an inhibitor of non-structural protein 3 4A protease with EC50 values of 1 and 0.21 nM for HCV 1a and HCV 1b, respectively.

Dasabuvir (ABT-333) sodium is a non-nucleoside hepatitis C virus (HCV) polymerase inhibitor that exhibits inhibition of the RNA-dependent RNA polymerase (RNA polymerase) encoded by the HCV NS5B gene. Dasabuvir sodium inhibited genotype 1a (strain H77) replicon (EC50: 7.7 nM) and 1b (strain Con1) replicon (EC50: 1.8 nM).

Deleobuvir sodium is the salt form of Deleobuvir, also known as BI207127, a non-nucleoside hepatitis C virus NS5B polymerase inhibitor for the treatment of hepatitis C. Deleobuvir was tested in combination regimens with pegylated interferon and ribavirin, and in interferon-free regimens with other direct-acting antiviral agents including faldaprevir. Deleobuvir showed that a triple combination of deleobuvir, faldaprevir, and ribavirin performed well in HCV genotype 1b patients. Efficacy fell below 50%, however, for dual regimens without ribavirin and for genotype 1a patients. In December 2013, deleobuvir was discontinued since recent findings from phase III trials did not suggest sufficient efficacy.

Ledipasvir hydrochloride (GS-5885) is a hepatitis C virus NS5A inhibitor, demonstrating potent activity with EC50 values of 34 pM for genotype 1a replicon and 4 pM for genotype 1b replicon. It also functions as a SARS-CoV 3CL pro inhibitor with an IC50 of 1.62 µM [3].
