The development of heteronuclear metal complexes as potent anticancer agents has received increasing attention in recent years. In this study, two new heteronuclear Ru(Ⅱ)-Re(Ⅰ) metal complexes, Ru(bpy)LRe(CO)(DIP) and Ru(phen)LRe(CO)(DIP) [ and , L = 2-(4-pyridinyl)imidazolio[4,5-f][1,10]phenanthroline, bpy = 2,2'-bipyridine, DIP = 4,7-diphenyl-1,10-phenanthroline, phen = 1,10-phenanthroline], were synthesized and characterized. Cytotoxicity assay shows that and exhibit higher anticancer activity than cisplatin, and exist certain selectivity toward human cancer cells over normal cells. The anticancer mechanistic studies reveal that and can induce apoptosis through the regulation of cell cycle, depolarization of mitochondrial membrane potential (MMP), elevation of intracellular reactive oxygen species (ROS), and caspase cascade. Moreover, and can effectively inhibit cell migration and colony formation. Taken together, heteronuclear Ru(Ⅱ)-Re(Ⅰ) metal complexes possess the prospect of developing new anticancer agents with high efficacy.
近年来，异核金属配合物作为高效抗癌剂的开发受到了越来越多的关注。在本研究中，合成并表征了两种新型异核Ru(Ⅱ)-Re(Ⅰ)金属配合物，Ru(bpy)LRe(CO)(DIP)和Ru(phen)LRe(CO)(DIP) [L = 2-(4-吡啶基)咪唑并[4,5-f][1,10]菲咯啉，bpy = 2,2'-联吡啶，DIP = 4,7-二苯基-1,10-菲咯啉，phen = 1,10-菲咯啉]。细胞毒性试验表明，与顺铂相比，这两种配合物表现出更高的抗癌活性，并且对人癌细胞比对正常细胞具有一定的选择性。抗癌机制研究表明，这两种配合物可通过调节细胞周期、线粒体膜电位（MMP）去极化、细胞内活性氧（ROS）升高和半胱天冬酶级联反应来诱导细胞凋亡。此外，这两种配合物还能有效抑制细胞迁移和集落形成。综上所述，异核Ru(Ⅱ)-Re(Ⅰ)金属配合物具有开发高效新型抗癌剂的前景。
