Galidesivirtriphosphate is a substrate for viral RNA-dependent RNA polymerase (RDRP), resulting in termination of viral RNA replication and thus serves as an antiviral. Galidesivirtriphosphate inhibits HCV NS5B RNA polymerase activity and protects mice against Ebola. Galidesivirtriphosphate (Immucillin-A triphosphate) is converted by the prodrug Galidesivir.
Galidesivir is a viral RNA-dependent RNA polymerase (RdRP) inhibitor and broad spectrum antiviral nucleotide.In vitro, galidesivir displays antiviral activity against a range of RNA viruses, including bunyaviruses, arenaviruses, paramyxoviruses, coronaviruses, and flaviviruses (EC50values range from 3 μM to >100 μM). Galidesivir protects against Ebola and Marburg viral infection in animal models.
