A series of new benzimidazole bearing thiazolidinedione derivatives has been designed, synthesized by using conventional as well as microwave-assisted methods. Microwave-assisted synthesis caused a significant reduction in the reaction times and improvement in the yields of all the derivatives. All the new synthesized compounds were evaluated for their in vitro cytotoxic potential against selected
已经设计了一系列新的带有噻唑烷二酮衍生物的苯并咪唑衍生物,它们是通过常规方法以及微波辅助方法合成的。微波辅助合成大大缩短了反应时间,并提高了所有衍生物的收率。评估了所有新合成的化合物对乳腺癌(MDAMB-231),前列腺癌(PC-3),宫颈癌(HeLa),肺癌(A549)和骨癌(HT1080)的选定人类癌细胞系的体外细胞毒性潜力,以及正常的肾细胞(HeK-293T)。发现化合物17n,17p和17q具有IC 50的强细胞毒性在PC-3,HeLa,A549和HT1080癌细胞上,该值在0.096–0.63μM的范围内。与癌细胞相比,已发现大多数化合物对正常的HeK-293T肾细胞是安全的。用17p和17q处理细胞表现出典型的凋亡形态特征,例如细胞核的碎裂和收缩。此外,测试化合物通过破坏F-肌动蛋白组装而导致细胞迁移受到抑制。Hoechst,DCFH-DA染色,线粒体膜和膜联蛋白结合试验表明,
