psi 7977

Sofosbuvir (GS 7977) is a uridine monophosphate analog inhibitor of hepatitis C virus (HCV) polymerase NS5B that is used as an antiviral agent in the treatment of chronic hepatitis C.

PSI-7409 is the active 5'-triphosphate metabolite of Sofosbuvir (PSI-7977).

Sofosbuvir D6 is the deuterium labeled Sofosbuvir. Sofosbuvir is an active inhibitor of HCV RNA replication in the HCV replicon assay, demonstrates potent anti-hepatitis C virus (HCV) activity.

Sofosbuvir impurity H, a diastereoisomer of Sofosbuvir (PSI-7977), is an impurity of Sofosbuvir, which is an HCV RNA replication inhibitor with potent anti-hepatitis C virus activity.

PSI-7409 tetrasodium is the pharmacologically active 5′-triphosphate metabolite of sofosbuvir (PSI-7977) that directly inhibits hepatitis C virus NS5B RNA-dependent RNA polymerase, with IC50 values of 1.6, 2.8, 0.7, and 2.6 μM against GT 1b_Con1, GT 2a_JFH1, GT 3a, and GT 4a NS5B polymerases, respectively, PSI-7409 tetrasodium is widely used to study antiviral mechanisms and genotype-specific polymerase inhibition.
