What is Galidesivir?

Galidesivir is an adenosine analog that is metabolized intracellularly to its active triphosphate form. The triphosphate is incorporated into the growing viral RNA strand by the viral RNA-dependent RNA polymerase, causing premature chain termination and blocking viral transcription and replication. It is studied in filovirus infections, including Ebola virus infection and Marburg virus disease.
