Novel series of 3-substituted 2,6-difluorobenzamide derivatives as FtsZ inhibitors were designed, synthesized and evaluated for their in vitro antibacterial activity against various phenotype of Gram-positive and Gram-negative bacteria, and their cell division inhibitory activity against three representative strains. As a result, 3-chloroalkoxy derivative 7, 3-bromoalkoxy derivative 12 and 3-alkyloxy
设计,合成和评估了一系列新型的3-取代的2,6-二氟苯甲酰胺衍生物作为FtsZ抑制剂,它们对革兰氏阳性和革兰氏阴性细菌的各种表型具有体外抗菌活性,并且对三种代表性菌株具有细胞分裂抑制活性。其结果是,3-chloroalkoxy衍生物7,3- bromoalkoxy衍生物12和3-烷氧基衍生物17被发现表现出对最佳的抗菌活性的枯草芽孢杆菌与0.25-1微克/毫升的MIC的,和良好的活性(MIC <10微克/ mL)对抗敏感和耐药的金黄色葡萄球菌。另外,这三种化合物对枯草芽孢杆菌和金黄色葡萄球菌均显示出有效的细胞分裂抑制活性,MIC值低于1μg/ mL 。
