This work reports the synthesis and antibacterial activity of novel hydrazone derivatives 8a-k bearing 4-[3-methyl-4-(methylsulfonyl)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.
本研究报道了新型氢肼衍生物8a-k的合成及其抗菌活性,这些衍生物具有4-[3-甲基-4-(亚磺酸基)pyridin-2-yl]基团。采用1H NMR、质谱和红外光谱等技术对这些氢肼衍生物进行了表征。合成的氢肼衍生物通过纸盘扩散法对一组细菌菌株进行了抗菌活性测试,菌株包括大肠杆菌、铜绿假单胞菌、金黄色葡萄球菌和化脓性链球菌。化合物8b、8d、8e、8f、8h、8i对测试生物表现出良好的抗菌活性。
