Derivatives of a novel heterocyclic system ethyl 2-(2-(aryl)-9-(aryl)imidazo [1,2-c]thieno [3,2-e]pyrimidin-3-yl)acetate have been obtained by successive reactions in four stages; Knoevenagel condensation between acetophenone derivatives with malononitrile to give 2-(1-arylethylidene)malononitrile, closing the thiophene ring in the latter to form 3-amino-2-5-arylthieno [2,3-d]pyrimidin-4-amines by
通过连续反应得到了新型杂环体系2-(2-(芳基)-9-(芳基)咪唑[1,2- c ]噻吩并[3,2- e ]嘧啶-3-基)乙酸乙酯的衍生物分四个阶段;苯乙酮衍生物与丙二腈进行Knoevenagel缩合,得到2-(1-芳基亚乙基)丙二腈,后者封闭噻吩环,形成3-氨基-2-5-芳基噻吩并[2,3-d]嘧啶-4-胺甲酰胺,以及3-氨基-2-5-芳基噻吩[2,3- d]嘧啶-4-胺环、Meldrum酸和各种芳基乙二醛。新化合物的结构根据元素分析和光谱数据得到确认。还检查了一些选定的合成化合物的抗癌活性。虽然化合物10a-j对于所测试的三种细胞系并不是相当有效,但与依托泊苷相比,化合物10c还是有一定潜力的。
