A series of forty different pyrazole containing benzimidazole hybrids (6–45) have been designed, synthesized and evaluated for their potential anti-proliferative activity against three human tumor cell lines - lung (A549), breast (MCF-7), and cervical (HeLa). Some of the compounds, specifically 9, 17, and 28, showed potent growth inhibition against all the cell lines tested, with IC50 values in the
已设计,合成和评估了一系列四十种不同的含吡唑的苯并咪唑杂种(6 – 45),它们对三种人类肿瘤细胞系(肺(A549),乳腺(MCF-7)和子宫颈( HeLa)。某些化合物,特别是9,17,和28,显示对测试的所有细胞系的有效的生长抑制,IC 50值在0.83–1.81μM的范围内。乳腺癌细胞被用于进一步的详细研究,以了解化合物抑制细胞生长和诱导细胞凋亡的作用机理。这些化合物的治疗严重影响了MCF-7乳腺癌细胞的形态,细胞迁移和长期克隆形成存活率。流式细胞仪揭示了该化合物通过下调细胞周期蛋白D2和CDK2而在细胞周期的G1期阻滞了MCF-7细胞。荧光染色和DNA片段化研究表明,细胞凋亡被细胞凋亡的诱导所抑制。此外,还发现这些化合物导致线粒体膜电位(DΨm)崩溃,活性氧(ROS)含量增加。
