thymidylate kinase (MtbTMPK) for the synthesis of thymidine triphosphates and thus also DNA synthesis. Therefore, this enzyme constitutes a potential Achilles heel of the pathogen. Based on a previously reported MtbTMPK 6-aryl-substituted pyridine inhibitor and guided by two co-crystal structures of MtbTMPK with pyridone- and thymine-based inhibitors, we report the synthesis of a series of aryl-shifted cyanopyridone
结核分枝杆菌是结核病的病原体,它依赖胸苷酸激酶 ( Mtb TMPK) 来合成三磷酸胸苷,从而也合成 DNA。因此,这种酶构成了病原体的潜在致命弱点。基于先前报道的Mtb TMPK 6-芳基取代吡啶抑制剂,并以Mtb TMPK 与吡啶酮和胸腺嘧啶抑制剂的两种共晶结构为指导,我们报告了一系列芳基转移氰基吡啶酮类似物的合成。这些化合物通常缺乏显着的Mtb TMPK 抑制效力,但一些类似物确实表现出有希望的抗结核活性。模拟11i证明与文献化合物5相比,抗结核活性增加了 10 倍(MIC H37Rv,1.2 μM)。许多具有全细胞抗分枝杆菌活性的类似物没有明显的细胞毒性。
