2-Methyleneaminonaphthalene smoothly reacts with cyclic beta-diketones to afford azaphenanthrene derivatives in high yield. The dihydropyridine ring in the products can be oxidized to pyridine ring. The oxidation products, unlike their precursors and analogs having an aryl substituent in the a-position with respect to the nitrogen atom, react with hydroxylamine at the carbonyl group to give the corresponding oximes and in some cases undergo Knoevenagel condensation with malononitrile. Hydrolysis of the condensation product yields the respective diamide.

A composition for use in inhibiting the binding of a Norovirus to the histo-blood group antigen on the surface of epithelia is disclosed. The composition may contain a therapeutically effective amount of a binding-inhibiting compound and a carrier and/or excipient. The compounds may competitively bind a Norovirus that has the capability of binding with the histo-blood group antigens of secretor blood type, including A, B, AB, and O blood types. The compositions may be administered to a human prior to or after infection by a Norovirus, to prevent, ameliorate, or reduce the effects of an infection.
