  解决革兰氏阴性细菌中氟喹诺酮耐药性的拓扑异构酶抑制剂。

  摘要：

  自从五十年前发现喹诺酮类抗生素以来，作为广谱药物，已经取得了巨大成功，它通过双重抑制细菌DNA促旋酶和拓扑异构酶IV发挥其活性。在GyrA / ParC喹诺酮耐药性确定区域中，基于靶点的突变在很大程度上推动了耐药率的上升，侵蚀了其实用性，并威胁了这一至关重要的抗生素类药物的未来使用。本文中，我们描述了一系列4-（氨基甲基）喹啉-2（1 H）-one的发现和优化，以34为例，它们抑制细菌DNA促旋酶和拓扑异构酶IV并显示出对环丙沙星耐药的革兰氏阴性病原体的有效活性。X射线晶体学分析表明34 在拓扑异构酶IV-DNA裂解复合物中占据经典的喹诺酮结合位点，但是不与喹诺酮抗性确定区域中的残基形成显着接触。
