Sofosbuvir CAS# 1190307-88-0 索非布韦

Sofosbuvir, also known as PSI-7977 and GS7977 (brand names Sovaldi and Virunon), is a drug used for hepatitis C virus (HCV) infection, with a high cure rate. It inhibits the RNA polymerase that the hepatitis C virus uses to replicate its RNA. It was discovered at Pharmasset and developed by Gilead Sciences. Sofosbuvir 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.
