Due to the side effects of marketed cancer drugs, we designed a series of ruthenium-based fluorescent anticancer drugs, which was demonstrated to be target specific, highly cytoselective, lipophilic, water soluble, hypoxia efficient and glutathione resistant. Herein, we developed novel ruthenium(II)-p-cymene-2-aryl-imidazophenanthroline scaffolds as effective DNA-targeting agents. Specifically, the 2-aryl substituted imidazophenanthroline ligands make the Ru(II) complex a decent DNA intercalator by affording planarity. Among the four Ru(II) complexes (RuL1–RuL4), [(η6-p-cymene)RuIICl{K2-N,N-(2-(naphthalene-1-yl)-1H-imidazo[4,5-f][1,10]phenanthroline)}]PF6 (RuL4) exhibited the best cytoselectivity in two cancer cell lines (Caco-2 and HeLa), and [(η6-p-Cymene)RuIICl{K2-N,N-(2-(anthracen-9-yl)-1H-imidazo[4,5-f][1,10]phenanthroline)}]PF6 (RuL1) was established as a potent HeLa cell imaging probe.

低氧有效且耐谷胱甘肽的细胞选择性钌(II)-对-异丙基-芳基咪唑并菲咯啉配合物:生物分子相互作用和活细胞成像。

由于市售抗癌药的副作用,我们设计了一系列基于钌的荧光抗癌药,已证明它们具有靶向特异性,高度细胞选择性,亲脂性,水溶性,低氧效率和谷胱甘肽抗性。在这里,我们开发了新型的钌(II)--cymene-2-芳基-咪唑并菲咯啉骨架作为有效的DNA靶向剂。具体地,通过提供平面性,2-芳基取代的咪唑并菲咯啉配体使Ru(II)络合物成为体面的DNA嵌入剂。在四个的Ru(II)络合物(RuL1-RuL4),[(η 6 - p -cymene)钌II氯[KP 2 - ÑN-(2-(萘-1-基)-1 H-咪唑并[4,5- f ] [1,10]菲咯啉)}] PF 6RuL4)在两种癌细胞系中均表现出最佳的细胞选择性(Caco -2和HeLa)和[(η 6 - p -Cymene)钌II氯[KP 2 - ññ - (2-(蒽-9-基)-1- ħ -咪唑并[4,5- ˚F ] [ 1,10]菲咯啉}} PF 6RuL1)被确立为有效的HeLa细胞成像探针。
