In view of their DNA intercalation activities as anticancer agents, novel twenty four [1,2,4]triazolo[4,3-a]quinoxaline derivatives have been designed, synthesized and evaluated against HepG2, HCT-116 and MCF-7 as DNA intercalators and Top II enzyme inhibitors. The data obtained from molecular modeling studies revealed that, our small aromatic molecules were concluded to act through two ways firstly
考虑到它们作为抗癌剂的DNA插入活性,已设计,合成和评估了新的二十四[1,2,4]三唑并[4,3- a ]喹喔啉衍生物作为DNA的HepG2,HCT-116和MCF-7嵌入剂和Top II酶抑制剂。从分子模型研究中获得的数据表明,我们的芳香小分子可以通过两种方式起作用,首先是通过与直接结合的蛋白质与DNA的非共价相互作用,从而抑制了拓扑异构酶II。第二个是通过非共价结合于DNA的双螺旋结构或者通过嵌入粘合剂作为在化合物10一和11 d或小沟中结合的化合物8 ë和8 c。细胞毒活性表明MCF-7和HepG2分别是对新衍生物影响最敏感的细胞系。特别是化合物10一个,11 d和8 ë被认为是最有效的衍生物整体针对与IC三个HepG2细胞,HCT116和MCF-7癌细胞系所测试的化合物50 =(4.55±0.3,6.18±0.8和3.93±0.6 µM),(5.61±0.5、6.49±0.5和3.71±0
