dose-dependent manner, targeting different apoptotic proteins expression: 11 increased the expression of pro-apoptotic Bax protein while 18–20 reduced the level of anti-apoptotic Bcl-2 protein. Compounds 18 and 19 also reduced MDA-MB-231 cells proliferation as measured by Ki-67 staining. Furthermore, compounds were also tested for the ability to inhibit cell migration in the highly aggressive human MDA-MB-435s
在此,我们报告了新型仿生咪唑并[1,2- a :4,5 c' ]联吡啶的设计、合成和评估。结构优化确定了四种抗增殖化合物。化合物11,18,19和20表现出优异的抗癌活性的体外与IC 50 0.4-5μM针对三种人癌细胞系的(MDA-MB-468,MDA-MB-435S和MDA-MB-231)。这四种化合物诱导的细胞凋亡中的MDA-MB-231细胞以剂量依赖的方式,针对不同的细胞凋亡蛋白表达:11增加促凋亡Bax蛋白表达而18 - 20降低抗凋亡 Bcl-2 蛋白的水平。通过 Ki-67 染色测量,化合物18和19还降低了 MDA-MB-231 细胞增殖。 此外,还测试了化合物在高度侵袭性的人类 MDA-MB-435s 细胞系中抑制细胞迁移的能力。该系列的六种化合物 ( 8, 15, 18, 22, 23, 24 ) 抑制了 41–50% 的细胞迁移,而四种化合物 ( 20 , 25 , 27
