摘要: 对3种单核钌配合物[Ru(bpy)2(paH)]PF6(1), [Ru(dmb)2(paH)]PF6(2), [Ru(phen)2(paH)]PF6(3) (bpy=2,2'-联吡啶, dmb=4,4'-二甲基-2,2'-联吡啶, phen=菲咯啉, paH=2-吡啶甲酸)进行合成,并通过元素分析、红外、核磁和电喷雾质谱对其进行表征。此外,对配合物进行了光谱学和电化学测试,电化学实验表明1~3在0.7~1.0 V范围内均有1个氧化还原峰,说明钌中心发生了氧化还原反应。最后通过MTT法(MTT为3-(4, 5-二甲基噻唑-2)-2,5-二苯基四氮唑溴盐)对配合物进行了体外细胞毒性实验,结果表明:1~3对人乳腺癌细胞、胃癌细胞和肺癌细胞都表现出浓度依赖性,即随着配合物浓度的逐渐增大,细胞的存活率逐渐降低。值得注意的是2对乳腺癌细胞表现出非常明显的抑制作用(IC50=2.85 μmol·L-1)。 |

Abstract: Three new mononuclear ruthenium complexes [Ru(bpy)2(paH)]PF6(1), [Ru(dmb)2(paH)]PF6(2) and [Ru(phen)2(paH)]PF6(3)(bpy=2,2'-bipyridine,dmb=4,4'-dimethyl-2,2'-bipyridine, phen=phenanthroline, paH=pyridinecarboxylic acid) were synthesized and characterized using elemental analysis, infrared, nuclear magnetic spectroscopy and electrospray ionization mass spectrometry.Their photophysical and electrochemical properties were also studied. The complexes 1~3 undergo metal centered oxidation and the Ru(Ⅱ)/Ru(Ⅲ) redox couple peak are in 0.7~1.0 V versus a saturated calomel electrode. The cytotoxicity of these complexes in vitro was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay. The results indicated that 1~3 exhibited significant dose-dependent cytotoxicity to human breast cancer (MCF-7), gastric cancer (AGS) and lung cancer (A549) tumour cell lines. It is worth noting that 2 showed excellent antitumor effects in a cellular study (IC50 value of 2.85 μmol·L-1 for human breast cancer cells in vitro). |
