Biological target:
Remdesivir O-desphosphate acetonide impurity is an impurity of Remdesivir. Remdesivir (GS-5734), a nucleoside analogue with effective antiviral activity and is highly effective in the control of SARS-CoV-2 (COVID-19) infection in vitro.
In vitro activity:
In vitro, Remdesivir (RDV) exhibited antiviral activity against a clinical isolate of SARS-CoV-2 in primary human airway epithelial cells with a half-maximal effective concentration of 9.9 nM and also potently (280 nM) inhibited SARS-CoV-2 replication in Calu-3 human lung cells. In biochemical assays assessing RDV-triphosphate incorporation by the SARS-CoV-2, SARS-CoV, and MERS-CoV viral RNA-dependent RNA polymerase complexes, RDV triphosphate was selectively incorporated over the natural nucleotide substrate adenosine triphosphate and inhibited viral RNA synthesis with a half-maximal inhibitory concentration value of 32 nM for MERS-CoV. Reference: Clin Pharmacokinet. 2021 Mar 30 : 1–15. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8007387/
In vivo activity:
In vivo, Remdesivir (RDV) showed therapeutic efficacy in SARS-CoV-2-infected rhesus monkeys and prophylactic and therapeutic efficacy in MERS-CoV-infected rhesus monkeys. Briefly, 12 h after inoculation with SARS-CoV-2, rhesus monkeys received an RDV 10-mg/kg IV loading dose followed by maintenance doses of RDV 5 mg/kg at 24 h post-inoculation and once daily thereafter for a total of 6 days of treatment. The aim of the loading dose was to rapidly generate high GS-443902 concentrations following the first dose. Treatment with this regimen resulted in a significant reduction in clinical signs of respiratory disease, lung pathology and gross lung lesions, and viral RNA levels compared with vehicle-treated animals.
