topoisomerase I inhibitors, and antiproliferative compounds. Both cationic systems behave as DNA intercalators and exhibit antiproliferative activity. The pentacyclic benzo[f]quino[2,1-a]phthalazinium cations also have an inhibitory effect on the catalytic activity of DNA topoisomerase I, without trapping of cleavage complexes. Structural characterization using density functional theory indicates that the
新的氮杂喹啉鎓类阳离子已从异色烷中获得。合成过程分七个步骤完成,其中一个关键特征是分子内Westphal缩合反应。分子内过程的第一个例子允许制备苯并[f]吡啶基[2,1-a]邻苯二甲鎓和苯并[f]喹啉[2,1-a]邻苯二甲鎓盐,这些盐被评估为DNA嵌入剂,DNA拓扑异构酶I抑制剂和抗增殖化合物。两种阳离子系统均起DNA嵌入剂的作用,并表现出抗增殖活性。五环苯并[f]喹啉[2,1-a]酞菁阳离子也对DNA拓扑异构酶I的催化活性具有抑制作用,而不会捕获裂解复合物。使用密度泛函理论的结构表征表明,稠环系统略为非平面,
