tcsc0016935 JTK-853

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

IC50 & Target: HCV polymerase^[1]


EC50: 0.38 μM (1a H77 HCV), 0.035 μM (1b Con1 HCV)^[1]

In Vitro: JTK-853 is a novel, non-nucleoside Hepatitis C Virus Polymerase inhibitor which shows effective antiviral activity in HCV replicon cells with EC₅₀s of 0.38 and 0.035 µM in genotype 1a H77 and 1b Con1 strains, respectively. When JTK-853 is incubated with the replicon cells for 48 h, it shows antiviral activity against genotype 1a H77 and 1b Con1 replicon cells with EC₉₀ values of 6.5±0.5 and 0.34±0.05 µM, respectively. At 10 µM, JTK-853 induces apparent Huh-7.5 cell death in 2-week culture. JTK-853 suppresses the drug-resistant colony formation in the genotype 1a replicon cells, and the numbers of JTK-853-resistant colonies are much lower than those of GS-9190-resistant colonies for both genotypes_[1].
