To address the emergency caused by multi-drug resistant Staphylococcus aureus, a series of novel capsaicin derivatives with nitrothiophene substituents have been designed and evaluated for the antibacterial activities against S. aureus Newman and multidrug-resistant strains (NRS-1, NRS-70, NRS-100, NRS-108, and NRS-271). The structure-activity relationship was further revealed. Compound 13c, 13f, and
为了解决由多药耐药
金黄色葡萄球菌引起的紧急情况,已设计了一系列具有硝基
噻吩取代基的新型
辣椒素衍
生物,并评估了其对
金黄色葡萄球菌纽曼菌和多药耐药菌株(NRS-1,NRS-70, NRS-100,NRS-108和NRS-271)。构效关系得到进一步揭示。化合物13c,13f和13g对葡萄球菌的生长具有高活性,最小抑菌浓度(MIC)值为0.39-1.56μg/ mL。恶二唑衍生的化合物21(酯13f的
生物甾醇)是MIC值为0.20-0.78μg/ mL的5种具有多重耐药性的
金黄色葡萄球菌菌株抗生长的最有效候选者,与体外
万古霉素相比,其活性更高。值得注意的是
