An antiviral nucleoside analog
GS-441524 is an antiviral nucleoside analog and the active metabolite of remdesivir. [1] GS-441524 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). 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).[2]
