Obeldesivir (ATV006) is a potent, orally active antiviral agent and ester proagents of GS-441524. Obeldesivir inhibits the replication of SARS-CoV-2 and its variants. Obeldesivir can be used for SARS-CoV-2 research[1].
Obeldesivir (0.001-100 μM; 48 h; Vero E6 cells) inhibits the replication of authentic SARS-CoV-2 and its variants of concern. Obeldesivir has an overall >4-fold and >12-fold potency improvement in inhibiting the replication of Delta and Omicron variants, with EC50 values of 0.349 μM and 0.106 μM, respectively[1].
Obeldesivir (5-25 mg/kg; p.o. and i.v.; Sprague Dawley rats) has favorable pharmacokinetic profiles in rats with high oral bioavailability (F %) of 81.5% and maximum blood concentration (Cmax) of 8.2 μM[1].
Obeldesivir (250-500 mg/kg; p.o.; daily, for 4 days; hACE2 knock-in and Ad5-hACE2 mice) has antiviral activity and inhibits SARS-CoV-2 replication in mouse models[1].
Obeldesivir (100-250 mg/kg; p.o.; daily, for 10 days) reduces lung damage and protects K18-hACE2 mice[1].
Obeldesivir (10-150 mg/kg; p.o.; daily, for 3 days) reduces virus titers and lung damage caused by Delta variant infection in K18-hACE2 mice[1].
