A set of 5-ethynylarylnaphthalimides was synthesized by Sonogashira cross-coupling reactions and evaluated for antiproliferative and antitopoisomerase II in vitro activities. Furthermore docking studies of these molecules as DNA-intercalators were carried out and the in vivo DNA-damaging activity was also determined with the model organism Saccharomyces cerevisiae. From the obtained results three naphthalimides
通过Sonogashira交叉偶联反应合成了一组5-

萘二甲
酰亚胺,并评估了其在体外的抗增殖和抗拓扑异构酶II活性。此外,还对这些分子作为DNA嵌入剂进行了对接研究,并且还使用模型
生物酿酒酵母(Saccharomyces cerevisiae)确定了体内的DNA破坏活性。从获得的结果来看,三种
萘二甲
酰亚胺6、13和14显示出强的拓扑异构酶II抑制活性。这三种分子也使用自互补寡聚
脱氧核苷酸d(ATGCAT)2作为模型,作为DNA嵌入剂也表现出良好的对接分数,化合物13和14在体内DNA破坏活性中是最具细胞毒性的。
