2'-O-Methylcytidine is a nucleoside derivative and an inhibitor of hepatitis C virus (HCV) non-structural protein 5B (NS5B; IC50= 3.8 μM).1It inhibits HCV replication in a replicon assay (IC50= 21.2 μM). 1.Migliaccio, G., Tomassini, J.E., Carroll, S.S., et al.Characterization of resistance to non-obligate chain-terminating ribonucleoside analogs that inhibit hepatitis C virus replication in vitroJ.

Dasabuvir (ABT-333) is a non-nucleoside inhibitor of the hepatitis C virus (HCV) non-structural protein 5B (NS5B), an RNA-dependent RNA polymerase. Upon administration and intracellular uptake, dasabuvir binds HCV NS5B polymerase, blocking viral RNA synthesis and replication. The HCV NS5B protein is essential for the replication of the HCV RNA genome.

Beclabuvir is an allosteric inhibitor that binds to thumb site 1 of the HCV NS5B RNA-dependent RNA polymerase, inhibiting recombinant NS5B proteins from HCV genotypes 1, 3, 4, and 5 (IC50 < 28 nM).

GS-6620 is a HCV nonstructural protein 5B (NS5B) inhibitor.

GS-9851, a HCV nonstructural protein 5B (NS5B) inhibitor, is used potentially for the treatment of HCV infection.

MB-11362, a HCV nonstructural protein 5B (NS5B) inhibitor, is used potentially for the treatment of HCV infection.

VX 759, a nonstructural protein 5B (NS5B) inhibitor, is used potentially for the treatment of HCV infection.

6-Hydroxypyridin-3-ylboronic acid is a heterocyclic building block.1,2It has been used in the synthesis of non-nucleoside inhibitors of hepatitis C virus (HCV) RNA-dependent RNA polymerase nonstructural protein 5B (NS5B).16-Hydroxypyridin-3-ylboronic acid has also been used in the synthesis of mammalian target of rapamycin (mTOR) inhibitors.2 1.Hendricks, R.T., Spencer, S.R., Blake, J.F., et al.3-Hydroxyisoquinolines as inhibitors of HCV NS5b RNA-dependent RNA polymeraseBioorg.

HCV-IN-43 (compound 2), an HCV NS5B protein inhibitor, efficiently inhibits HCV virus replication and is utilized in the study of HCV infection [1].

HCV-IN-44 (compound 28) is an inhibitor of the HCV NS5B protein, effective in suppressing HCV virus replication and useful for researching HCV infection [1].

2'-O-Methylguanosine-5'-O-triphosphate (2'-methyl GTP) acts as an inhibitor targeting the hepatitis C virus (HCV) non-structural protein 5B (NS5B; with an IC50 of 3.5 µM), and serves as an active metabolite of the prodrug IDX184 through a 2'-methylguanosine intermediate transformation. Additionally, at a concentration of 50 µM, it promotes tubulin polymerization. Notably, levels of 2'-methyl GTP are reduced in the tumoral tissues of patients with hepatocellular carcinoma in comparison to the adjacent normal tissues.

Nesbuvir is a selective hepatitis C virus (HCV) nonstructural protein 5B (NS5B) RNA-dependent polymerase inhibitor.Nesbuvir has an IC50 of 9 nM against hepatocellular carcinoma cells containing 1b HCV replicons.
