Onradivir
Based on 1 Customer Validation
Onradivir (ZSP1273) is an orally active antiviral agent targeting influenza A virus RNA polymerase PB2 subunit with an IC50 of 0.562 nM. Onradivir inhibits cap binding to influenza A virus RNA polymerase PB2 subunit, suppresses viral replication, reduces viral titres and RNA loads, and inhibits influenza A virus infection. Onradivir maintains high survival rates in influenza A virus-infected mice, and reduces influenza A virus titers in a murine model. Onradivir can be used for the research of influenza A virus infection.

Onradivir (ZSP1273) (10 mg/kg; p.o.; twice daily; 7 days) provides 100% survival when administered 4 h pre-infection, improves survival when administered 48 h post-infection, provides partial survival when administered 72 h post-infection, and extends time to death when administered 96 h post-infection in influenza A virus WSN/33 (H1N1)-infected female BALB/c mice[2].
Onradivir (ZSP1273) (30-100 mg/kg; p.o.; twice daily; 7 days) provides 100% survival at 30 mg/kg, and provides high survival with minimal deaths at 100 mg/kg, when administered starting 48 h post-infection in influenza A virus WSN/33 (H1N1)-infected female BALB/c mice[2].
Onradivir (ZSP1273) (25 mg/kg; p.o.; twice daily; 5 days) significantly reduces nasal lavage viral load and maintains stable body weight in influenza A virus/California/07/2009 (H1N1)-infected female ferrets when administered starting 4 h pre-infection[2].
