Biological Activity for GS 441524

GS 441524 is a viral RNA-dependent RNA polymerase (RdRp) inhibitor and broad spectrum antiviral nucleotide; active metabolite of Remdesivir (Cat. No. 7226). Competes with natural nucleoside triphosphates, blocking viral RNA synthesis. Exhibits antiviral activity against viruses from Coronaviridae family including SARS-CoV-2 in vitro, and SARS-CoV and feline infectious peritonitis virus (FIPV) in vitro and in vivo. Inhibits SARS-CoV and MERS-CoV- infected HAE cultures (EC50 values are 0.18 and 0.86 μM, respectively) and inhibits murine hepatitis virus (MHV) (EC50 = 1.1 μM).
