through different alkane or alkylamide spacers was prepared. Their anticancer activity, DNA thermal denaturation studies, restriction endonuclease digestion assay and flow cytometric analysis in human melanoma cell line (A375) were investigated. One of the compounds of the series 17d showed significant anticancer activity with promising DNA-binding ability and apoptosis caused G0/G1 phase arrest at
制备了一系列通过不同烷烃或烷基酰胺间隔基连接的苯并噻唑和苯并恶唑连接的吡咯并苯并二氮杂共轭物。研究了它们在人黑素瘤细胞系(A375)中的抗癌活性,DNA热变性研究,限制性内切酶消化测定和流式细胞仪分析。17d系列化合物之一显示出显着的抗癌活性,并具有有前途的DNA结合能力,并且在亚微摩尔浓度下,细胞凋亡导致G0 / G1相停滞。为了确定结合方式并了解DNA结合相互作用的结构要求,使用金进行分子对接研究程序,并使用包括明确溶剂在内的分子力学-泊松-玻尔兹曼表面积(MM-PBSA)方法进行了更严格的2 ns分子动力学模拟。此外,评价了化合物17d在人结肠癌HT29异种移植小鼠中的体内功效研究。
