Nesbuvir is a novel selective inhibitor of nonstructural protein 5B (NS5B) polymerase with IC50 value of 5 nM [1].
NS5B (nonstructural protein 5B) is a viral protein found in HCV and plays an important role in HCV RNA replicate by using the viral positive RNA strand as its template and catalyzing the polymerization of rNTP during RNA replication. As the principal catalytic enzyme for HCV replication, NS5B is a viable target for HCV-RNA replication and used as a target for HCV therapy [2] [3].
Nesbuvir is a selective NS5B polymerase inhibitor and has a different selectivity with the reported ALK inhibitor crizotinib. When tested with Huh7.5 cell line, nesbuvir showed the highest selectivity for NS5B and mutations reduced the cells susceptibility [1]. In Clone A cells derived from Huh-7 cells containing approximately 1,000 genome copies of HCV genotype 1b replicon per cell, nesbuvir treatment with the concentration of 0.1 and 1 μM for 16-day reduced about 3.6 log10 and 4.2 log10 HCV RNA levels, respectively [2].
In the chimeric mouse model, nesbuvir treatment resulted in a 2.02 +/- 0.55 log reduction in HCV titer, whereas in combination with interferon using a suboptimal dose of 30 mg/kg three times per day showed a 2.44 log reduction and were better than interferon treatment only [4].

Applications |
Nesbuvir is an inhibitor of the hepatitis C virus （HCV）nonstructural protein 5B (NS5B) polymerase. It has potent and specific inhibitory effect against the HCV RdRp, thus inhibiting RNA synthesis. When Nesbuvir is used in combination with boceprevir, it decreases the frequency with which resistant variants occur in Huh7-BB7 cells bearing a subgenomic genotype 1b HCV replicon. |
| Animal experiment [2]: | |
|
Animal models |
Urokinase plasminogen activator (uPA)/severe combined immunodeficient (SCID) mice |
|
Dosage form |
Oral administration, 50 mg/kg，three times daily for 5 days |
|
Application |
Treating mice with Nesbuvir resulted in a 2.02 ± 0.55 log10 decrease of HCV titer with one mouse below the level of detection, whereas HCV levels in the control group of mice were relatively stable (0.26 ± 0.16 log10 decline). |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
