PSI-6206 13CD3

Description: PSI-6206 13CD3 (RO-2433 13CD3; GS-331007 13CD3; Sofosbuvir metabolite GS-331007 13CD3) is the deuterium labeled form of PSI-6206. PSI-6206 is the deaminated derivative of PSI-6130, which is a potent and selective inhibitor of HCV NS5B polymerase. PSI-6206 inhibits HCV replicon with EC90 of > 100 uM. Sofosbuvir (also known as PSI-7977, GS-7977; trade names Sovaldi and Virunon) is a HCV NS5B polymerase inhibitor that is used for the treatment of chronic hepatitis C virus (HCV) infection. Sofosbuvir acts by inhibiting the RNA polymerase that the hepatitis C virus uses to replicate its RNA. It is a component of the first all-oral, interferon-free regimen approved for treating chronic Hepatitis C. In 2013, the FDA approved sofosbuvir in combination with ribavirin (RBV) for oral dual therapy of HCV genotypes 2 and 3, and for triple therapy with injected pegylated interferon (pegIFN) and RBV for treatment-naive patients with HCV genotypes 1 and 4.
