of novel Mycobacterium tuberculosis type II dehydroquinase (DHQase) inhibitors were discovered through the use of a fragment elaboration approach. Putative active site binding fragments were initially assessed in silico which led to the selection of two small aromatic fragments for further investigation. Synthetic elaboration of the fragments provided a library of 34 inhibitors that exhibited low‐micromolar
通过使用片段精细化方法发现了新型的结核分枝杆菌II型脱氢奎宁酶(DHQase)抑制剂文库。最初通过计算机评估了推定的活性位点结合片段,从而选择了两个小的芳香片段进行进一步研究。片段的合成加工提供了34种抑制剂的文库,这些抑制剂表现出对II型DHQase的低微摩尔抑制作用。在体外针对结核分枝杆菌的筛选中,许多这些抑制剂在低微摩尔范围内也表现出抗菌活性。这些现在用作进一步开发用于治疗结核病的疗法的先导化合物。
