PSI-7409 tetrasodium is an active 5'-triphosphate metabolite of sofosbuvir (PSI-7977)(IC50s of 1.6, 2.8, 0.7 and 2.6 μM for GT 1b_Con1, GT 2a_JFH1, GT 3a, and GT 4a NS5B polymerases, respectively).
Ciluprevir is an effective and selective HCV NS3 protease inhibitor with proven antiviral effect in humans. Ciluprevir may be an antiviral agent for individuals infected with non-genotype-1 HCV. In vitro sensitivity studies with Ciluprevir showed a decrea
The nucleocapsid of the hepatitis B virus is covered by an envelope of HBV surface antigen (HBsAg), which has the common, group-specific determinant a. The four major subtypes of HBsAg, adw, adr, ayw and ayr, are generated, and they have been proposed to
GSK-2336805 is a HCV NS5A inhibitor. GSK2336805 retained activity on chimeric replicons containing NS5A patient sequences from genotype 1 and patient and consensus sequences for genotypes 4 and 5 and part of genotype 6.
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.
7(Z)-Pentacosene is an unsaturated cuticular hydrocarbon that acts as a contact sex pheromone in fruit flies. In different species and genotypes of Drosophila, it can be found on both males and females. Pentacosene may stimulate copulation either by itself at high concentrations or when combined with other alkenes. Interestingly, the absolute level of pentacosene increases in Drosophila females immediately after copulation.
Beclabuvir, also known as BMS-791325, is an allosteric inhibitor that binds to thumb site 1 of the hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase. BMS-791325 inhibits recombinant NS5B proteins from HCV genotypes 1, 3, 4, and 5 at 50% inhibitory concentrations (IC50) below 28 nM. In cell culture, BMS-791325 inhibited replication of HCV subgenomic replicons representing genotypes 1a and 1b at 50% effective concentrations (EC50s) of 3 nM and 6 nM, respectively, with similar (3 to 18 nM) values for genotypes 3a, 4a, and 5a.

BI-1388 is a highly potent inhibitor of HCV NS3 protease activity, inhibiting viral replication for various HCV genotypes and for resistant mutants D168V and R155K.
