A broad-spectrum antiviral prodrug with potent in vitro antiviral activity against a diverse panel of RNA viruses such as Ebola virus, MERS-CoV and SARS-CoV. It is currently in Phase III clinical trials for the treatment of Covid-19 in adults. It has a role as an antiviral drug, a prodrug and an anticoronaviral agent. It is a carboxylic ester, a pyrrolotriazine, a nitrile, a phosphoramidate ester, a C-nucleoside and an aromatic amine. It is functionally related to a GS-441524."}]
