Synthesis of Novel Benzohydrazides Bearing 4-[3-Methyl-4-(methylsulfonyl)pyridin-2-yl] Moiety as Potential Antibacterial Agents

摘要

This work reports the synthesis and antibacterial activity of novel hydrazone derivatives 8a-k bearing 4-[3-methyl-4-(methylsuIfonyl)pyridin-2-yl] moiety. Spectroscopic techniques like ~1H NMR, mass and IR tools was utilized for the characterization of these hydrazone derivatives. The synthesized hydrazone derivatives were tested against a set of bacterial strains, namely, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus pyogenes by paper disc diffusion method. Compounds 8b, 8d, 8e, 8f, 8h, 8i showed good antibacterial activity against the test organisms.
