Galidesivir (BCX4430), an adenosine analog and a direct-acting antiviral agent, disrupts viral RNA-dependent RNA polymerase (RdRp) activity. Galidesivir is active in vitro against many RNA viral pathogens, including the filoviruses and emerging infectious agents such as MERS-CoV, SARS-CoV, and SARS-CoV-2. Galidesivir inhibits some negative-sense RNA viruses with EC50s ranging from ~3 to ~68 μM[1][2][3].
