Synthesis, structures and biological activity of some 4-amino-3-cinnolinecarboxylic acid derivatives, part 1

This work describes the synthesis of 4-amino-3-cinnolinecarboxamides, which were then hydrolyzed to corresponding 4-amino-3-cinnolinecarboxylic acids. Several compounds were tested for their antibacterial and antifungal activity, and for the central nervous system effect.

Synthesis of Azoles and Fused Azoles from α-Arylhydrazononitriles

The reaction of α-arylhydrazononitriles (I) with phenylhydrazine, hydrazine hydrate, p-phenylenediamine, mercaptoacetic acid, and phenyl isothiocyanate gives amidrazone (IIa-c, III), pyrazolone (IVa-c), benzimidazole (X), 4-thiazolone (XIe,d) and 1,2,4-tr
