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].

| Dosage: | 250 and 500 mg/kg |
| Administration: | Oral administration; daily, for 4 days |
| Result: | Inhibited gRNA and sgRNA, which is Biomarkers of coronavirus replication. Reduced the viral load and pathological damage of the lung. |
| Animal Model: | K18-hACE2 mice[1] |
| Dosage: | 100 and 250 mg/kg |
| Administration: | Oral administration; daily, for 10 days |
| Result: | Reduced viral RNA and increased the survival rate of mice. Reduced evidence of lung pathology and the production of inflammatory cytokines and chemokines in the lung tissues. |
