The synthesis of new derivatives of the planar tricyclic pyrimido[1,2-a]benzimidazole system featuring protonable sidechains in the 3 and/or 10 positions is described. The reported literature procedures for the preparation of the intermediate 3-ethoxycarbonylpyrimido[1,2-a]benzimidazol-4(10H)-one 15, starting from 2-aminobenzimidazole 18 and diethyl ethoxymethylenemalonate, were revised. The interaction
描述了平面三环嘧啶并[1,2- a ]苯并咪唑体系新衍生物的合成,该衍生物在3和/或10位具有质子化侧链。修改了从2-氨基苯并咪唑18和乙氧基亚甲基丙二酸二乙酯开始制备中间体3-乙氧基羰基嘧啶并[1,2- a ]苯并咪唑-4(10 H)-one 15的文献报道方法。初步研究了与DNA的相互作用,固有结合常数以及多种化合物(1–8,10,11)的抗增殖活性。
