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.

In Vitro

Cellular kinases phosphorylate Galidesivir (BCX4430) to a triphosphate that mimics ATP; viral RNA polymerases incorporate the drug's monophosphate nucleotide into the growing RNA chain, causing premature chain termination^[1].
Galidesivir effectively inhibits the infection of Vero cells with YFV. The EC50 determined by the neutral red uptake assay is 8.3 μg/ml (24.5 μM)^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Galidesivir (BCX4430) is active after intramuscular, intraperitoneal, and oral administration in a variety of experimental infections. In nonclinical studies involving lethal infections with Ebola virus, Marburg virus, Rift Valley fever virus, and Yellow Fever virus, Galidesivir has demonstrated pronounced efficacy^[1].
Galidesivir (4 mg/kg; i.p.; twice daily for 7 days) is effectively in a hamster model of yellow fever (YF)^[4].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
