摘要
合成了新的双核铜(Ⅱ)配合物:[Cu2(DMSO)2(ODPA)4]·2DMSO(其中,DMSO=二甲基亚砜,ODPA=N-邻苯二甲酰甘氨酸)。通过X-射线单晶衍射测定了该配合物的结构。配合物晶体属于三斜晶系,空间群P1,晶胞参数:a=1.036 1(2)nm,b=1.127 3(2)nm,c=1.212 6(2)nm,α=84.084(2)°,β=81.765(3)°,γ=82.163(2)°;晶胞体积V=1.383 6(4)nm3,晶胞结构基元数Z=1,D c=1.508 g·cm-3,最后的残差因子:R=0.075 0,wR2=0.192 7。用紫外和荧光光谱等方法研究了配合物与DNA的相互作用。结果表明,配合物以部分插入方式与DNA作用,凝胶电泳实验结果表明,该配合物能够切割pBR322 DNA成FormⅡ。
A new copper(n) complex [Cuz(DMSO)z(ODPA)4]·2DMSO (DMSO=dimethyl sulfoxide, ODPA=N- Phthaloylglycinate) was synthesized and characterized by single-crystal X-ray diffraction. The complex crystallizes in the triclinic system, space group Pi, with cell parameters: a=10.361(2) nm, b=11.273(2) nm, c=12.126(2) nm, β=81.765(3)°, cell volume; V=1 383.6(4) nm3, number of molecules inside the cell: Z=I, Do=1.508 g.cm-3, the final R=0.075 0 and wR2=0.192 7. The interaction of the complex with DNA was studied by UV spectroscopy, EtBr fluoescent probe and DNA cleavage. The results indicate that the complex could interact with DNA by partial intercalative mode. The agarose gel electrophoresis studies revealed that the complex can cleave pBR322 DNA to Form 11.
