A series of bisindole–pyrrolobenzodiazepine conjugates (5a–f) linked through different alkane spacers was prepared and evaluated for their anticancer activity. All compounds exhibited significant anticancer potency and the most potent compounds 5b and 5e were taken up for detailed studies on MCF-7 cell line. Cell cycle effects were examined apart from investigating the inhibition of tubulin polymerization
制备了一系列通过不同烷烃间隔基连接的双吲哚-吡咯并苯并二氮杂卓共轭物(5a - f),并评估了它们的抗癌活性。所有化合物均显示出显着的抗癌效力,最有效的化合物5b和5e被吸收用于MCF-7细胞系的详细研究。除了研究微管蛋白对2μM的化合物2a,2b,5b和5e的抑制作用外,还研究了细胞周期效应。FACS分析表明,在较高浓度(4和8μM)下,亚G1期细胞增加,而G2 / M期细胞减少,因此表明化合物5b5e和5e有效引起MCF-7细胞凋亡。还观察到化合物5b和5e显示出组蛋白脱乙酰基酶蛋白水平例如HDAC1、2、3、8的下调和p21水平的升高,随后凋亡细胞死亡。这些化合物的凋亡性质由MCF-7细胞中裂解的PARP和活性caspase-7的表达增加进一步证明。
