Galidesivir triphosphate is a substrate for viral RNA-dependent RNA polymerase (RDRP), resulting in termination of viral RNA replication and thus serves as an antiviral. Galidesivir triphosphate inhibits HCV NS5B RNA polymerase activity and protects mice against Ebola. Galidesivir triphosphate (Immucillin-A triphosphate) is converted by the prodrug Galidesivir.
Balapiravir (R1626, Ro 4588161) is the prodrug of a nucleoside analogue inhibitor of the hepatitis C virus (HCV) RNA-dependent RNA polymerase (R1479, RG1479). IC50 Value: Target: HCV Balapiravir was discontinued for safety reasons in 28-36% of patients (m
JTK-853 is a novel, non-nucleoside inhibitor of Hepatitis C Virus (HCV) polymerase. It also displays effective antiviral activity in HCV replicon cells (EC50s: 0.38 and 0.035 µM in genotype 1a H77 and 1b Con1 strains, respectively).
GSK-625433, a homochiral inhibitor of the hepatitis C virus (HCV) RNA-dependent RNA polymerase, has the ability to inhibit the polymerase of both HCV genotypes 1a and 1b.
