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.

4 Pharmacology and Biochemistry
4.1 Pharmacology

Galidesivir is an adenosine analogue with a broad-spectrum antiviral activity against RNA viruses, including flaviviruses, togaviruses, bunyaviruses, arenaviruses, paramyxoviruses, coronaviruses, filoviruses, orthomyxoviruses, and picornaviruses.


4.2 MeSH Pharmacological Classification

Antiviral Agents

Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)


4.3 Mechanism of Action

Galidesivir works by binding to viral RNA polymerase where the natural nucleotide would bind, leading to the structural change in the viral enzyme due to altered electrostatic interactions. Disruption of viral RNA polymerase activity results in premature termination of the elongating RNA strand.
