Carbazoloquinone alkaloids are of great interest as privileged structures for anticancer drug molecules. The purpose of this study was to investigate the structure-activity relationships of carbazoloquinone derivatives as anticancer agents. A series of carbazoloquinones including murrayaquinone A, koeniginequinones A and B, and related analogues were therefore prepared. Palladium-catalyzed intramolecular
咔唑醌生物碱作为抗癌药物分子的特权结构备受关注。本研究的目的是研究咔唑醌衍生物作为抗癌剂的构效关系。因此制备了一系列的咔唑醌,包括Murrayaquinone A,Koeniginequinones A和B,以及相关的类似物。通过DFT计算可以很好地阐明钯催化的分子内环化反应机理。合成衍生物的处理以剂量依赖的方式显示出对人白血病HL-60细胞的细胞毒性。另外,Murrayaquinone A和β-brazanquinone升高了细胞的活性氧(ROS)水平,从而触发了细胞凋亡。我们的发现强调了咔唑醌衍生物作为ROS诱导抗癌剂的巨大潜力。
