New derivatives of the indolo[3,2- e][1,2,3]triazolo[1,5- a]pyrimidine system, substituted in the 4 position, were designed as novel antitumor agents because of their theoretical capability to form stable complexes with DNA fragments. The calculated free energies of binding were found in the range -12.76 --> -39.68 Kcal/mol. The docking studies revealed a common binding mode with the chromophore intercalated
吲哚并[3,2-e] [1,2,3]三唑并[1,5-a]嘧啶系统的新衍生物在4位上被取代,因为它们具有形成稳定化合物的理论能力,因此被设计为新型抗肿瘤药DNA片段的复合物。发现计算的结合自由能在-12.76-> -39.68 Kcal / mol的范围内。对接研究揭示了一种常见的结合模式,生色团插入GC碱基对之间,而侧链则沿着次要凹槽。根据对接研究选择并适当合成的化合物对所研究的每种类型的肿瘤细胞系均表现出抗增殖活性,通常在低微摩尔范围内。活性更高的衍生物显示为1eJ和1eL,分别具有针对肾脏和中枢神经系统子面板的显着抗增殖活性。
