目录号 : KCM10789 CAS No. : 1241946-89-3 纯度 : ≥98%
Simeprevir is an orally bioavailable and potent inhibitor of the hepatitis C virus (HCV) nonstructural protein 3/4A (NS3/4A) protease (K = 0.36 nM), a serine protease essential for HCV replication. It inhibits HCV viral replication with an EC value of 7.8 nM in Huh7 replicon cells using a luciferase-based assay. Simeprevir is effective against the HCV genotypes 1a and 1b in biochemical assays. In Huh7 replicon cells, it is synergistically effective when used in combination with IFN-α or NM-107 and has an additive effect when used with ribavirin . Formulations containing simeprevir have been used, alone or in combination with pegylated IFN-α and ribavirin, for the treatment of HCV.

生物活性

Simeprevir sodium is an oral, potent and highly specific hepatitis C virus (HCV) NS3/4A protease inhibitor with a Ki of 0.36 nM. Simeprevir sodium inhibits HCV replication with an EC50 of 7.8 nM. Simeprevir sodium also potently suppresses SARS-CoV-2 replication and synergizes with Remdesivir. Simeprevir sodium inhibits the main protease (Mpro) and the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2, and also modulates host immune response.
