- CAS No.: 2375241-19-1
- Formula:C22H24F2N6O3
- Molecular Weight:458.46
InChIKey: XUXVTSUIFIUZSZ-MJSCHBGXSA-N
SMILES: FC1=CN=C2C(C(C3=NC(N[C@@H]4[C@H](C5CCC4CC5)C(O)=O)=C(F)C(C6CC6)=N3)=NN2)=C1.O
Biological Activity: Onradivir (ZSP1273) monohydrate is an orally active antiviral agent targeting influenza A virus RNA polymerase PB2 subunit with an IC50 of 0.562 nM. Onradivir monohydrate 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 monohydrate maintains high survival rates in influenza A virus-infected mice, and reduces influenza A virus titers in a murine model. Onradivir monohydrate can be used for the research of influenza A virus infection[1][2].
