Remdesivir nucleoside monophosphate is a metabolite of Remdesivir[1]. Remdesivir is a nucleoside analogue with effective antiviral activity against SARS-CoV and MERS-CoV[2].

ChEBI: GS-441524 monophosphate is a C-nucleoside phosphate that is GS-441524 in which the 5'-hydroxy group has been replaced by a phosphate group. In cells, GS-441524 monophosphate gets converted into the pharmacologically active triphosphate form (GS-443902). It has a role as an anticoronaviral agent, an antiviral drug and a drug metabolite. It is a C-nucleoside phosphate, an aromatic amine, a nitrile and a pyrrolotriazine. It is functionally related to a GS-441524.
