Two Cu(Ⅱ) complexes of [Cu(2,6-DPC)(Hnta)(H_2O)]·H_2O(2,6-DPC = 2,6-pyridinedicarboxylic-carboxylate, Hnta = nicotinic acid) and [Cu_2(2,4-D)_4(Hnta)_2](2,4-D = 2,4-dichlorophenoxyacetic-carboxylate) were synthesized and successfully obtained as single crystals in this paper. The supramolecular structures of the complexes from zero to three dimensions and the weak intermolecular force in the crystal were analyzed. The single-crystal structures of the complexes were further analyzed by Hirshfeld surface analysis. The competition capacity of the complexes about calf thymus DNA(ct-DNA) was also analyzed by fluorescence spectroscopy. The ability of complexes to cleave the plasmid DNA(pBR322-DNA) was determined by gel electrophoresis assay. And at last, the complexes' cytotoxic activities were reviewed for four kinds of cancer cell lines(HeLa, MCF-7, HepG, SKOV-3), showing that the coordination polymer has anti-tumor activity and cytotoxicity. 相似文献

合成了一个喹啉-2-羧酸根锰配位聚合物{[Mn(Qina)_2(Bpp)]·2/3H_2O}_n,(Qina=2-quinolinecarboxylic-carboxylate,Bpp=4,4′-trimethylenedipyridine)并制得其单晶。运用元素分析、红外光谱和X射线单晶衍射等方式表征了配合物结构。晶体结构分析表明,每一个Mn(Ⅱ)被2个Qina分子螯合并通过Bpp配体桥联而形成一维线性结构;一维分子链通过分子链间的C-H…π及π…π作用构筑得配合物三维超分子结构。分别利用溴化乙锭荧光光谱法、琼脂糖凝胶电泳法研究了配合物对小牛胸腺DNA及质粒DNA的结合活性及切割活性。配合物表现出了一定的DNA结合力与切割活性。并利用MMT比色法,测试了配合物对Hela,MCF-7肿瘤细胞株的体外毒性,配合物表现出了一定的体外细胞毒性。 相似文献
