基于钌(Ru)的复合物显示出开发抗癌药物的有希望的前景。在细胞毒性Ru配合物中,Ru芳烃配合物以在生理条件下在水中的较高溶解度而闻名。但是,需要更多信息来了解水合反应对这些金属配合物的抗癌功效的作用和影响。在此,研究了具有有效抗癌活性的Ru(II)芳烃络合物[Ru(II)(C 6 H 6)(3-MOIP)Cl] Cl(RuMOP)的水合过程,并通过紫外可见分光光度法进行了表征光谱法,11 H NMR光谱法和HPLC分析。结果表明,水溶液中的水合反应迅速发生,氯化物配体被氢取代。此外,水合过程改变了复合物在肿瘤细胞中的细胞吸收,最终影响了其抗增殖活性。亲本复合物RuMOP可以激活caspase家族蛋白和p53信号通路,与肿瘤细胞膜和死亡受体有高水平的相互作用。但是,这些细胞事件和信号传导可能被水合反应所阻断。综上所述,这些结果有助于我们理解芳烃钌配合物的抗癌作用机理,并为合理设计这类具有更好癌症治疗潜能的金属配合物提供重要信息。

We also study the luminescent properties for the ligand and compound 1, and the results suggest that title compound is very thermal stable and worthy of further study as candidate of potential photoluminescence material.

The intermolecular C H⋯O interactions extend the complex 1 into 2D networks, and the existing H-bonds further stabilized the complexes 1–2, which can be proved by TGA experiment. Furthermore, the solid-state

Two coordination polymers, [Mn(dipt)(m-BDC)3] n (1) and [Pb(mip)(1,4-NDC)] n (2) [dipt?=?2-(2,4-dichlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, mip?=?2-(3-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, m-BDC?=?isophthalic acid, 1,4-NDC?=?naphthalene-1,4-dicarboxylic acid], have been synthesized by hydrothermal reactions and characterized by elemental analysis, thermogravimetric analysis, infrared spectrum, and single-crystal X-ray diffraction. Single-crystal X-ray diffraction reveals that 1 and 2 have 1-D chain architecture. Complex 1 has a 2-D-layered structure constructed from CH center dot center dot center dot O hydrogen bonds. Complex 2 has a 2-D-layered structure constructed from NH center dot center dot center dot O hydrogen bonds and pp interactions. TG analyses suggest 1 and 2 have excellent thermal stabilities from hydrogen bonds and pp interactions. Mn(II) in 1 has trigonal bipyramidal geometry surrounded by three carboxylate oxygen atoms from three monodentate bridging m-BDC and two nitrogen atoms from one dipt. Pb(II) has [:PbN2O4] pentagonal bipyramidal geometry in 2. The luminescent properties for dipt, mip, 1, and 2 are also presented.
