Nesbuvir (previously known as VB-19796 and HCV-796) is an inhibitor of hepatitis C NS5B RNA-dependent RNA polymerase. The drug was tested in phase II in patients with hepatitis C in combination with rebetol and peg-intron, however, its development was terminated due to safety issues.

Sample Use Guides

Nesbuvir is administered at a dose of 500 mg, every 12 hours for 48 weeks (in combination with rebetol and peg-intron).
Route of Administration: Oral
Cells bearing a genotype 1b HCV replicon were treated multiple times with 0.1 and 1 uM nesbuvir. At the end of the 16-day treatment, about 3.6 log10 and 4.2 log10 reductions of HCV RNA levels were observed, respectively. The concentration of the compound that inhibited 50% of the HCV RNA level was 9 nM.
