    ECHEMI Editorial Reference
    GS-441524 is a nucleoside analogue that terminates the RNA chain of viral RNA-dependent RNA polymerase. GS-441524 was developed by Gilead Sciences, Inc as part of their research into human RNA virus disease such as Ebola. GS-441524 is a small molecule that exhibits potent antiviral activity against a number of RNA viruses, including the zoonotic severe acute respiratory syndrome (SARS) coronavirus ( Cho et al., 2012).
    GS-441524 is a C-nucleoside analog that is (2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-carbonitrile substituted by a 4-aminopyrrolo[2,1-f][1,2,4]triazin-7-yl group at position 2. It is the active metabolite of remdesivir and exhibits a broad range of inhibitory activity against various RNA viruses including HCV, parainfluenza and SARS-CoV. It has a role as a drug metabolite, an antiviral agent and an anticoronaviral agent. It is a pyrrolotriazine, a nitrile, a C-nucleoside and an aromatic amine.|GS-441524 is an adenosine nucleotide analog antiviral, similar to [remdesivir]. This molecule was patented in 2009. In vitro studies of GS-441524 have determined it has a higher EC50 than remdesivir against a number of viruses, meaning GS-441524 is less potent. GS-441524 continues to be studied in the treatment of Feline Infectious Peritonitis Virus, a coronavirus that only infects cats.
