GS-441524 exerts its antiviral effect by acting as a chain terminator during viral RNA synthesis. After cellular uptake, it is phosphorylated into its active triphosphate form (GS-443902), which mimics adenosine triphosphate. This active metabolite competitively inhibits the viral RNA-dependent RNA polymerase (RdRp) and, when incorporated into the growing RNA strand, causes premature chain termination, effectively halting the replication of RNA viruses such as coronaviruses and filoviruses.

This product is primarily indicated for the treatment of Feline Infectious Peritonitis (FIP) in cats, targeting both effusive (wet) and non-effusive (dry) forms of the disease, including cases with neurological symptoms. It is also utilized in research settings as a reference standard and intermediate for the development of broad-spectrum antiviral drugs against RNA viruses like SARS-CoV-2, MERS-CoV, and Ebola virus.
