Two dinuclear ruthenium（Ⅱ）complexes 1 and 2 with two Ru（bpy）2units（bpy=2,2′-bipyridine）linked by azo ligands BL1 and BL2 which were synthesized from benzidine,1,4-diamido-diphenyl ether and 8-hydroxyquinoline were synthesized and characterized by 1 H NMR,IR spectra,electrospray mass spectra and elemental analyses.Moreover,their electrochemical behavior,cytotoxic assays and cell cycle assays were studied.According to the studies,the two complexes were equally potent toward glioma cell（U251）,with the IC50 of 7.76 and 7.69μmol·L-1,respectively.However,the cytotoxicity of complex 2 doubled that of complex 1 on lung cancer cell（A549）and leukemia cell（K562）.The rigid BL1 and soft BL2 had an effect on the structure of the complexes 1 and2,which suggested that the bridging ligands were responsible for the different cytotoxic activity between the two complexes on A549 and K562.Cell cycle analysis indicated that the complexes 1 and 2 caused U251 cell cycle arrested in S phase and G0/G1 phase,respectively. 双核钌配合物 电化学 细胞毒性 细胞周期 dinuclear ruthenium（Ⅱ）complexes electrochemistry cytotoxicity cell cycle 10.14188/j.1671-8836.2015.01.009 O641.4 国家自然科学基金（21101121）;湖北省自然科学基金（2010CDB01301）;大连理工大学精细化工国家重点实验室开放基金（KF0912）资助项目 2015-01-01 2021-03-31 1 61
