摘要:

以半三明治钌(Ⅱ)(Ru1~Ru3)与1,3-双咪唑基苯配体(1~3)为前体, 合成了一系列钌(Ⅱ)矩形大环组装体 (4~12); 采用核磁共振波谱、 高分辨质谱、 元素分析和单晶X射线衍射表征了其组成和结构. 噻唑蓝(MTT)实验结果表明, 草酸型和苯醌型钌(Ⅱ)组装体4~9对测试的4种肿瘤细胞株均无毒性(IC50>100 μmol/L), 而萘醌型组装体10~12表现出较好的抗癌活性(IC50<2.22 μmol/L). 斑马鱼卵的急性毒性实验表明, 带有长烷氧基链的组装体12的毒性较低; 斑马鱼体内肿瘤实验表明, 组装体12在生物体内对A549(人肺癌细胞)有较好的抗癌作用. 研究表明, 组装体与DNA作用的主要方式是插入作用.

Abstract:

A series of ruthenium(Ⅱ) rectangular macrocyclic assemblies(4—12) was synthesized by half-sandwich ruthenium(Ⅱ)(Ru1Ru3) and 1,3-diimidazolebenzene ligands(13). The composition and structure of assemblies 4—12 were determined by nuclear magnetic resonance spectroscopy, high resolution mass spectroscopy, elemental analysis and single crystal X-ray diffraction. The toxicity of these ruthenium(Ⅱ) assemblies 4—12 to four human tumor cell lines was studied by MTT experiments, and it was found that the oxalic and benzoquinone ruthenium assemblies 4—9 exhibited little cytotoxic activity against the tumor cell lines(IC50>100 μmol/L), except that naphthoquinone ruthenium assemblies 10—12 showed good cytotoxic activity against all tested tumor cell lines(IC50<2.22 μmol/L). The acute toxicity experiment of zebrafish eggs showed that the toxicity of the assembly 12 was lower, and the tumor experiment in the zebrafish showed that the assembly 12 had a better anti-cancer effect in the organism. The results showed that the main interaction between Ru assembly and DNA was insertion.

Key words: Half-sandwich ruthenium(Ⅱ), Ruthenium(II) rectangular macrocyclic assembly, Anti-cancer activity
