A series of new N,N-dimethylaminopropyl- and 2-imidazolinyl-substituted derivatives of benzo[b]thienyl- and thieno[2,3-b]thienylcarboxanilides and benzo[b]thieno[2,3-c]- and thieno[3′,2′:4,5]thieno[2,3-c]quinolones were prepared. Quinolones were prepared by the reaction of photochemical dehydrohalogenation of corresponding anilides. Carboxanilides and quinolones were tested for the antiproliferative
苯并[ b ]噻吩基和噻吩并[2,3- b ]噻吩基甲酰胺和苯并[ b ]噻吩并[2,3- c ]-和噻吩的一系列新的N,N-二甲基氨基丙基-和2-咪唑啉基取代的衍生物[3',2':4,5] thieno [2,3- c制备了喹诺酮。喹诺酮是通过相应的苯胺的光化学脱卤化氢反应制备的。测试了甲酰苯胺和喹诺酮类药物的抗增殖活性。2-咪唑啉基取代的衍生物显示出非常突出的活性。通过使用实验获得的抗肿瘤测量结果,对这组化合物进行了3D衍生的QSAR分析。获得了可预测的3D衍生QSAR模型,并确定了对抗肿瘤活性影响最大的分子特性。羧苯胺6a – c和喹诺酮类9a – c和11a评估其DNA结合倾向和拓扑异构酶I和II抑制,作为其作用机理的一部分。作用方式的评估差异与3D-QSAR分析的结果很好地相关。两者合计,结果表明该系列化合物的哪些修饰应进一步改善其抗癌性能。
