Mycobacterium tuberculosis (Mtb) ATP synthase is an important target for treating drug-resistant infections and sterilizing the bacteria, spurring intensive efforts to develop new TB therapeutics based on this target. In this work, four novel series including furan-2(5H)-ketone (3, 4), maleimide (5) and squaramide (6) derivatives were designed, respectively, through the strategy of scaffold morphing
结核分枝杆菌(Mtb)ATP合酶是治疗耐药性感染和对细菌进行灭菌的重要目标,这促使人们大力投入以该目标为基础开发新的结核病疗法。在这项工作中,四种新型系列包括呋喃-2(5 ħ) -酮(3,4),马来酰亚胺(5)和squaramide(6)的衍生物被设计,分别通过支架变形和氢键介绍的策略,使用选择性Mtb ATP合酶抑制剂化合物2作为前导化合物。结果表明二氨基取代的环丁-3-烯-1,2-二酮化合物6ab6ah和6ah在体外具有良好的抗结核活性(MIC 0.452〜0.963μg/ mL),细胞毒性低(IC 50 > 64μg/ mL)。另外,化合物6ab不仅显示出对临床分离的抗药性菌株的有效活性,而且还显示出良好的可药物性概况,包括改善的代谢稳定性,无hERG通道抑制潜能以及可接受的口服生物利用度。与化合物2相比,对接研究和体外抗贝达喹啉抗性菌株试验的初步结果表明,Mtb ATP合酶很可能是
