In an effort to develop potent anti-cancer chemopreventive agents, a novel series of bisindole derivatives bearing oxime moiety were synthesized. Structures of all compounds were characterized by NMR and HRMS. Anti-proliferative activities for all of these compounds were investigated by the method of MTT assay on 7 human cancer lines and the normal cell lines (HUVEC). Most of them showed a noteworthy
为了开发有效的抗癌化学预防剂,合成了一系列新的带有肟部分的双吲哚衍生物。所有化合物的结构均通过NMR和HRMS表征。通过MTT测定法研究了所有这些化合物对7种人类癌症细胞系和正常细胞系(HUVEC)的抗增殖活性。他们中的大多数显示出显着的抗癌活性的体外中,半数抑制浓度(IC 50)值是4.31μM 4E对T24。Hoechst 33258和a啶橙/碘化丙啶染色的结果以及AnnexinV-FITC分析提供了凋亡细胞死亡的证据。化合物4e的进一步机理诱导的T24细胞凋亡表明化合物4e诱导了ROS的产生,并改变了抗凋亡蛋白和促凋亡蛋白,导致线粒体功能障碍以及激活caspase-9和caspase-3的激活,从而导致细胞凋亡。此外,细胞周期分析和蛋白质印迹分析表明,化合物4e有效地阻滞了G1期的T24细胞,并且可能对细胞周期调节蛋白特别是细胞周期蛋白D1有影响。
