Synthesis and antimicrobial activities of some newly 2,4,6-tri-substituted pyridine derivatives

Synthesis and antimicrobial activities of some newly 2,4,6-tri-substituted pyridine derivatives A series of novel 2-(2-(substituted benzylidene)hydrazinyl)-N′-(substituted benzylidene)-6-chloropyridine-4-carbohydrazide (5a–e), 2-(2-cycloalkylidenehydrazinyl)-6-chloro-N’-cyclo-alkylidenepyridine-4-carbohydrazide (6a,b), 2-(2-(1-(4-substituted phenyl)ethylidene)hydrazinyl)-6-chloro-N′-(1-(4-substituted phenyl)ethylidene)pyridine-4-carbohydrazide (7a,b) and 2-(2-(1-(pyridinyl)ethylidene)hydrazinyl)-6-chloro-N′-(1-(pyridinyl) ethylidene)pyridine-4-carbo-hydrazide (8a–c) derivatives have been synthesized by treating treating 2-chloro-6-hydrazinoisonicotinic acid hydrazide 4 with selected active reagents.

Abstract

A series of novel 2-(2-(substituted benzylidene)hydrazinyl)-N′-(substituted benzylidene)-6-chloropyridine-4-carbohydrazide (5a–e), 2-(2-cycloalkylidenehydrazinyl)-6-chloro-N’-cyclo-alkylidenepyridine-4-carbohydrazide (6a,b), 2-(2-(1-(4-substituted phenyl)ethylidene)hydrazinyl)-6-chloro-N′-(1-(4-substituted phenyl)ethylidene)pyridine-4-carbohydrazide (7a,b) and 2-(2-(1-(pyridinyl)ethylidene)hydrazinyl)-6-chloro-N′-(1-(pyridinyl) ethylidene)pyridine-4-carbo-hydrazide (8a–c) derivatives have been synthesized by treating treating 2-chloro-6-hydrazinoisonicotinic acid hydrazide 4 with selected active reagents. Their structures were confirmed by spectral and analytical data. The synthesized compounds were investigated for antimicrobial activities. The antimicrobial screening showed that many of these obtained compounds have good activities comparable to Streptomycin and Fusidic acid as reference drugs.
