2-Methoxy-4-(3-methyl-1-(4-(trifluoromethyl)phenyl)-1H-pyrazolo[3,4-b]pyridin-4-yl)phenol Chemical Properties,Usage,Production

Uses

ML303 is a pyrazolopyridine influenza virus nonstructural protein 1 (NS1) antagonist (IC90 = 155 nM), with an EC50 of 0.7 μM for Influenza A virus H1N1[1].

Biological Activity

It belongs to the pyrazolopyridine family.', 'ML303 is a potent inhibitor (IC50 = 155 nM) of the influenza viral protien NS1. NS1 enhances virulence by inhibiting host cell immune responses, including the expression of IFN-b, and regulating synthesis, splicing and translation of viral RNA.
