A new series of dual low nanomolar benzothiazole inhibitors of bacterial DNA gyrase and topoisomerase IV were developed. The resulting compounds show excellent broad-spectrum antibacterial activities against Gram-positive Enterococcus faecalis, Enterococcus faecium and multidrug resistant (MDR) Staphylococcus aureus strains [best compound minimal inhibitory concentrations (MICs): range, <0.03125–0
开发了一系列新的细菌 DNA 旋转酶和拓扑异构酶 IV 双重低纳摩尔苯并噻唑抑制剂。所得化合物对革兰氏阳性粪肠球菌、屎肠球菌和多重耐药(MDR)金黄色葡萄球菌菌株表现出优异的广谱抗菌活性[最佳化合物最低抑菌浓度(MIC):范围,<0 id=56>鲍曼不动杆菌和克雷伯氏菌肺炎链球菌(最佳复合 MIC:范围,1–4 μg/mL)。先导化合物7a经鉴定具有良好的溶解度和血浆蛋白结合性、良好的代谢稳定性、对细菌拓扑异构酶的选择性,并且没有毒性问题。 7a与铜绿假单胞菌GyrB24复合物的晶体结构揭示了其在ATP结合位点的结合模式。 7a和7h的扩展分析显示,对 100 多种 MDR 和非 MDR鲍曼不动杆菌菌株以及其他几种革兰氏阳性和革兰氏阴性菌株具有有效的抗菌活性。最终, 7a在万古霉素中型金黄色葡萄球菌大腿感染小鼠模型中的体内功效也得到了证实。
