Novel compounds of formulae (II, III) and pharmaceutical compositions have been found to inhibit inducible NOS synthase wherein: R4, R5, R6 and R7 are independently selected from the group consisting of hydrogen, lower alkyl, and halogen; and, R8 has the structure whrein X1, X2, X3, X4, X5, X6, R9, R13, R14 and n are as described herein.
An efficient method for the synthesis of polyfunctional imidazoles from vinyl azides and amidine has been developed. Starting from vinyl azide and amidine, this transformation proceeds without any additives and the obtained imidazoles can be decorated with ester functional group that is a promising site for further modification.
