design, synthesis, and structure-activity relationships of a range of analogues around the confirmed actives are described. Optimized leads with potent whole cell activity against H37Rv, no cytotoxicity flags, and in vivo efficacy in an acute murine model of infection are described. Mode-of-action studies suggest that the novel scaffold targets QcrB, a subunit of the menaquinol cytochrome c oxidoreductase
随着耐多药结核分枝杆菌菌株的出现,迫切需要具有新作用机制的新型口服药物。在这里,我们描述了一种新型吗啉代噻吩 (MOT) 系列的鉴定,该系列是在礼来公司图书馆对结核分枝杆菌菌株 H37Rv 进行表型筛选后进行的。描述了围绕已确认活性的一系列类似物的设计、合成和构效关系。描述了具有针对 H37Rv 的有效全细胞活性、无细胞毒性标志以及在急性鼠类感染模型中的体内功效的优化引线。作用模式研究表明,新型支架靶向 QcrB,甲基萘醌细胞色素 c 氧化还原酶的亚基,
