Galidesivir
Galidesivir is an adenosine analog and RNA polymerase inhibitor, with potential broad-spectrum antiviral activity. Upon administration, galidesivir is metabolized to its monophosphate form, which is then converted into the active triphosphate nucleotide. Galidesivir triphosphate binds to viral RNA-dependent RNA polymerase (RdRp) and gets incorporated into the growing viral RNA strand, which leads to premature chain termination. This prevents viral transcription and replication.
