GS-441524

GS-441524 is an antiviral nucleoside analog and a metabolite of remdesivir (Cay-30354). Upon entry into cells, GS-441524 is metabolized to an active triphosphate form that induces RNA chain termination and inhibits viral polymerases. It is active against Middle East respiratory syndrome coronavirus (MERS-CoV) and severe acute respiratory syndrome CoV (SARS-CoV) in infected primary human airway epithelial (HAE) cells (EC50s = 0.86 and 0.18 µM, respectively). GS-441524 reduces viral plaque formation in SARS-CoV-2-infected Vero E6 and Calu-3 2B4 cells (EC50s = 0.42 and 0.62 mM, respectively). It is cytoprotective against hepatitis C virus (HCV), yellow fever virus (YFV), dengue virus type 2 (DENV-2), influenza A, and parainfluenza 3 in cell-based assays (EC50s = 4.1, 11, 9.46, 27.9, and 1.71 µM, respectively).Formal Name: 2-C-(4-aminopyrrolo[2,1-f][1,2,4]triazin-7-yl)-2,5-anhydro-D-altrononitrile.
