A series of eleven 9-acridinyl amino acid derivatives were synthesized using a two-step procedure. Cytotoxicity was tested on the K562 and A549 cancer cell lines and normal diploid cell line MRC5 using the MTT assay. Compounds 6, 7, 8 and 9 were the most active, with IC50 values comparable to or lower than that of chemotherapeutic agent amsacrine. 8 and 9 were especially effective in the A549 cell
使用两步法合成了一系列11种9--啶基氨基酸衍生物。使用MTT测定法在K562和A549癌细胞系和正常二倍体细胞系MRC5上测试了细胞毒性。化合物6,7,8和9是最活跃的,具有IC 50个值相当或比化学治疗剂安吖啶的降低。8和9分别为在A549细胞系(IC是特别有效的50 ≈6μM),这是特别令人感兴趣的,因为安吖啶是不是在肺癌患者具有足够的活性。细胞周期分析显示7和9导致G2 / M阻滞,氨苯磺酸导致S期阻滞,而6和8则独立于细胞周期调控而诱导凋亡性细胞死亡。相比于安吖啶,6,7,8,和9显示出朝向拓扑异构酶II类似的抑制潜力,而只有7表明DNA嵌入性质。与此相反,以安吖啶,6,7,8和9显示出缺乏对未刺激的正常人白细胞毒性。
