Nesbuvir, also known as HCV-796 and VB-19796, is a potent and selective NS5B polymerase inhibitor with potent anti-hepatitis C virus activity in vitro, in mice with chimeric human livers, and in humans infected with hepatitis C virus. Enzyme assays yielded median inhibitory concentration (IC(50)) values of 0.01 to 0.14 microM for genotype 1, with half maximal effective concentration (EC(50)s) of 5 nM and 9 nM against genotype 1a and 1b replicons. HCV796 demonstrated potent anti-HCV activity consistently through enzyme inhibition assays, subgenomic replicon, and chimeric mouse studies.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
