are becoming common worldwide and new strategies for drug development are necessary. Here, we report the synthesis and evaluation of 2,4-dinitrophenylsulfonamides, which are donors of sulfur dioxide (SO2), a reactive sulfur species, as methicillin-resistant Staphylococcus aureus (MRSA) inhibitors. N-(3-Methoxyphenyl)-2,4-dinitro-N-(prop-2-yn-1-yl)benzenesulfonamide (5e) was found to have excellent in
耐药感染在世界范围内变得越来越普遍,并且新的药物开发策略是必需的。在这里,我们报告2,4-二硝基苯磺酰胺的合成和评估,这是一种活性硫物质二氧化硫(SO 2)的供体,作为耐甲氧西林的金黄色葡萄球菌(MRSA)抑制剂。N-(3-甲氧基苯基)-2,4-二硝基-N-(prop-2-yn-1-yl)苯磺酰胺(5e)具有优异的体外MRSA抑制能力。该化合物具有细胞渗透性,并用5e耗尽的细胞内硫醇和增强的氧化物种处理MRSA细胞,两者的结果均与涉及硫醇活化以产生SO 2的机理一致。
