(MIC = 1 μg/mL) was more active than norfloxacin against drug resistant MRSA. Compound 8b was able to disturb the membrane effectively and intercalate into deoxyribonucleic acid (DNA) to form a steady 8b-DNA complex, which might be responsible for bacterial metabolic inactivation. Molecular docking indicated that 8b could interact with DNA topoisomerase IV through noncovalent interactions to form a supramolecular
以乙酰苯胺为原料设计并合成了一类结构独特的对氨基苯磺酰基恶二唑类作为新型潜在抗菌剂。一些目标对氨基苯磺酰基恶二唑显示出抗菌效力。值得注意的是,己基衍生物8b (MIC = 1 μg/mL) 比诺氟沙星对耐药 MRSA 的活性更强。化合物8b能够有效地扰乱细胞膜并嵌入脱氧核糖核酸 (DNA) 中以形成稳定的8b- DNA 复合物,这可能是细菌代谢失活的原因。分子对接表明8b可通过非共价相互作用与 DNA 拓扑异构酶 IV 相互作用,形成超分子复合物并阻碍该酶的功能。这些结果表明,己基衍生物8b作为一种新的先导化合物值得进一步研究。
