A series of ruthenium(II) polypyridyl complexes were synthesized and evaluated for their in vitro anticancer activities. The results showed that ruthenium polypyridyl complexes, especially [Ru(bpy)2(p‐tFPIP)]2+ (2 a; bpy=bipyridine, tFPIP=2‐(2‐trifluoromethane phenyl)imidazole[4,5‐f][1,10]phenanthroline), exhibited novel anticancer activity against human cancer cell lines, but with less toxicity to
合成了一系列钌(II)聚吡啶基配合物,并对其体外抗癌活性进行了评估。结果表明,钌多吡啶基配合物,特别是[Ru(bpy)2(p- tFPIP)] 2+(2 a ; bpy =联吡啶,tFPIP = 2-(2-三氟甲烷苯基)咪唑[4,5- f ] [ 1,10]菲咯啉对人癌细胞具有新颖的抗癌活性,但对人正常细胞的毒性较小。流式细胞仪和caspase活性分析结果表明,2 a对MG-63骨肉瘤细胞诱导的生长抑制主要是由线粒体介导的细胞凋亡引起的。TUNEL-DAPI共染色检测到的DNA片段化和核浓缩进一步证实了2 a诱导的凋亡细胞死亡。此外,荧光成像显示钌(II)聚吡啶基复合物可以靶向线粒体以诱导线粒体片段化,并伴随着线粒体膜电位的消耗。综上所述,这些发现表明这些钌(II)配合物在癌症治疗中的潜在应用。
