制备了新颖的噻唑并[5,4- b ]喹啉衍生物,其在2-位带有或不带有(2-(氮杂环烷基)乙基)氨基取代基。评估了2位取代基对细胞毒活性,DNA嵌入和细胞毒特性的影响。带有脂族胺的2-位取代基有利于细胞毒性,而除去这些取代基则导致低或可忽略的细胞毒性。另外,新化合物在计算机上的计算机预测的结合模式与实验插层数据相关。这些结果表明2-位上的取代基对DNA嵌入性质的强烈影响。

effect of the substituent at 2-position on cytotoxicactivity, DNA-intercalation and cytotoxicproperties were evaluated. Substituents at 2-position bearing an aliphatic amine favored cytotoxicity, while removal of these substituents resulted in low or negligible cytotoxicproperties. Additionally, the in silico predicted binding mode of the novel compounds into DNA correlated with the experimental intercalation
