A series of novel nitrogen-containing macrocyclic bisbibenzyl derivatives was designed, synthesized, and evaluated for antiproliferative activity against three anthropic cancer cell lines. Among these novel molecules, the tri-O-alkylated compound 18a displayed the most potent anticancer activity against the A549, MCF-7, and k562 cancer cell lines, with IC50 values of 0.51, 0.23, and 0.19 μM, respectively
设计,合成了一系列新颖的含氮大环双联苄基衍生物,并评估了其对三种人类癌细胞系的抗增殖活性。在这些新分子中,三-O-烷基化的化合物18a对A549,MCF-7和k562癌细胞系表现出最强的抗癌活性,IC 50值分别为0.51、0.23和0.19μM 。明显优于母体化合物蓖麻毒素D,并且比临床使用的药物ADR好3-10倍。bis-Mannich衍生物11b的亚微摩尔IC 50也显示出显着增强的抗增殖能力价值观。还对这些新合成的化合物进行了构效关系分析。机理研究表明,这些化合物可靶向溶酶体以诱导溶酶体膜通透化,并且还可以诱导显示细胞凋亡和坏死特征的细胞死亡。
