The present invention is directed to the discovery of novel nonpeptidic small molecules that function as inhibitors of the influenza virus infection. In particular, the present invention is directed to the discovery of anti-influenza entry inhibitors with an aminoalkyl phenol ether structure that specifically target the influenza virus group 1 hemagglutinin (HA), the influenza virus envelope glycoprotein which mediates influenza virus entry through receptor binding and fusion of the virus with host cells.
Two series of easily accessible anilines were identified as inhibitors of influenza A virus subtype H1N1, and extensive chemical synthesis and analysis of the structure–activity relationship were performed. The compounds were shown to interfere with low pH-induced membrane fusion mediated by the H1 and H5 (group 1) hemagglutinin (HA) subtypes. A combination of virus resistance, HA interaction, and
