| In vitro | METHODS: RD, Huh7, and Vero cells were treated with Molnupiravir (MK-4482) (EIDD-2801) (1, 10, 100 μM) for cytopathic effect (CPE) protection assay. RESULTS EIDD-2801 showed stable CPE protection potential in a dose-dependent manner in multiple cell lines infected with EV-A71 virus; the value against EV-A71 virus was 70.12±4.40μM in RD cells; 88.52±3.18μM in Vero cells, and 35.64±0.47μM in Huh7 cells. [1] |
| In vivo | METHODS: Molnupiravir (MK-4482) (EIDD-2801) (50, 150, or 500 mg/kg, orally, every 12 hours) was used to prophylactically treat mice infected with SARS-CoV and observe its effects in mice. RESULTS Molnupiravir has potent antiviral activity and is able to prevent SARS-CoV replication and disease. [1] |
