of Mycobacterium tuberculosis, there is an urgent need to discover antituberculosis agent with novel structures. InhA, the enoyl acyl carrier protein reductase (ENR) from M. tuberculosis, is one of the key enzymes involved in the mycobacterial fatty acid elongation cycle and has been validated as an effective antimicrobial target. We report here the discovery, through high-throughput screening, of
鉴于结核分枝杆菌的多药耐药性在世界范围内的传播,迫切需要发现具有新颖结构的抗结核药。InhA是结核分枝杆菌的烯酰基酰基载体蛋白还原酶(ENR),是分枝杆菌脂肪酸延长周期中涉及的关键酶之一,已被证实是有效的抗菌靶标。我们在此报告通过高通量筛选发现的一系列吡咯烷羧酰胺,它们是一类新的强效InhA抑制剂。与三种抑制剂复合的InhA晶体结构已用于阐明抑制剂的结合模式。通过迭代微量滴定文库合成的后续优化,然后不经纯化就地进行活性筛选,可将先导化合物的效能提高160倍以上。
