5-tetrahydrobenzo[4,5] imidazo[1,2-c]pyrimidin-4-ol derivatives were designed and docked on the FtsZ protein crystal structure (PDB Id: 1RLU, resolution 2.08 Å). Compound 7t showed the highest docking score and H-bond interaction with Arg140 and Gly19. Our strategy for synthesis of (R)-2-(4′-chlorophenyl)-3-(4′-nitrophenyl)-1,2,3,5-tetrahydrobenzo[4,5]imidazo[1,2-c]pyrimidin-4-ol derivatives from o-phenylenediamine
丝状温度敏感突变体(FtsZ)是治疗结核病的新型靶标。一系列(R)-2-(4'-氯苯基)-3-(4'-硝基苯基)-1,2,3,5-四氢苯并[4,5]咪唑[1,2 - c ]嘧啶-4设计了-ol衍生物,并将其停靠在FtsZ蛋白晶体结构上(PDB ID:1RLU,分辨率为2.08)。化合物7t与Arg140和Gly19表现出最高的对接得分和氢键相互作用。我们合成(R)-2-(4'-氯苯基)-3-(4'-硝基苯基)-1,2,3,5-四氢苯并[4,5]咪唑[1,2- c ]嘧啶的策略如方案所示,由邻苯二胺衍生的-4-醇衍生物。所有合成的化合物都通过FTIR,质谱,1 H NMR,13 C NMR,元素分析和纯度通过HPLC和LCMS确认。化合物7g也通过单晶X射线分析确认。的,在硅片结果也证实与体外化合物的抗结核活性7吨。化合物7b分别在第1周和第2周后使用GAST / Fe培养基对结核分枝杆菌H
