摘要

合成了一种含有中性四齿nssn型配体的单核铜(II)配合物,其分子式为[Cu II(l1)Cl] clo4(1)],并以纯形式分离得到[其中l1˭1,3-二(3-吡啶基甲基硫)丙烷]。采用理化、光谱学、电导率等方法对绿铜配合物进行了表征。这些实验数据与所提出的复合物结构吻合良好。络合物(1)对小牛胸腺DNA和牛血清白蛋白的生物活性已经进行了系统的研究,并且从光谱研究中观察到铜(II)络合物1与小牛胸腺DNA的凹槽结合行为。

Synthesis and characterization of mononuclear copper(II) complex of tetradentate N2S2 donor set and the study of DNA and bovine serum albumin binding
One mononuclear copper(II) complex, containing neutral tetradentate NSSN-type ligands, of formulation [Cu II(L 1)Cl]ClO 4 (1), was synthesized and isolated in pure form [where L 1˭ 1,3-bis(3-pyridylmethylthio)propane]. Green-colored copper(II) complex was characterized by physicochemical, spectroscopic methods and conductivity measurement. These experimental data matched well with the proposed structure of the complex. Biological activity of the complex (1) toward calf thymus DNA and bovine serum albumin has been examined systematically and groove-binding behavior of the Copper(II) complex 1 with calf thymus DNA has been observed from the spectral study.
