Bivalent and polyvalent inhibitors can be used as antitumor agents. In this experiment, eight ligustrazine dimers and seven ligustrazine tetramers linked by alkane diamine with different lengths of carbon chain lengths were synthesized. After screening their antiproliferation activities against five cancer cell lines, most ligustrazine derivatives showed better cytotoxicity than the ligustrazine monomer
二价和多价抑制剂可用作抗肿瘤剂。本实验合成了8个川芎嗪二聚体和7个由不同碳链长度的烷二胺连接的川芎嗪四聚体。在筛选了它们对五种癌细胞系的抗增殖活性后,大多数川芎嗪衍生物显示出比川芎嗪单体更好的细胞毒性。特别是,与癸烷-1,10-二胺相连的川芎嗪二聚体 8e 在 FaDu 细胞中表现出最高的细胞毒性,IC50(50% 抑制浓度)值为 1.36 nM。进一步的机制研究表明,8e 可以通过线粒体膜电位的去极化和 S 期细胞周期阻滞诱导 FaDu 细胞凋亡。受这些结果的启发,合成并筛选了另外 27 个与癸烷-1,10-二胺相连的小分子杂环二聚体和 9 个带有醚链的肉桂酸二聚体。大多数单环和双环芳香系统对 FaDu 细胞显示出高度选择性的抗增殖活性,对正常 MCF 10A 细胞显示出低毒性。构效关系表明,两个末端酰胺键和链长为 8-12 个碳的烷基接头是维持其抗肿瘤活性的两个重要因素。此外,ADMET
