Background:
Remdesivir-d4is intended for use as an internal standard for the quantification of remdesivir by GC- or LC-MS. Remdesivir is a prodrug form of the antiviral nucleoside analog GS-441524 .1,2Upon entry into cells, remdesivir is metabolized into a nucleoside monophosphate form, which is further metabolized to an active nucleotide triphosphate that induces RNA chain termination and inhibits viral polymerases.3Remdesivir reduces viral titers in primary human airway epithelial (HAE) cells infected with Middle East respiratory syndrome coronavirus (MERS-CoV) or severe acute respiratory syndrome CoV (SARS-CoV; EC50s = 0.074 and 0.069 µM, respectively). It reduces infectious virus production in SARS-CoV-2-infected HAE cells (EC50= 10 nM).4In vivo, remdesivir (25 and 50 mg/kg) reduces lung viral titers and prevents weight loss in a mouse model of SARS-CoV infection.2Remdesivir (25 mg/kg) also reduces lung viral titers and lung hemorrhage and improves pulmonary function in mice infected with a chimeric SARS-CoV encoding the SARS-CoV-2 RNA-dependent RNA polymerase (RdRP).4Formulations containing remdesivir have been used in the treatment of COVID-19.
