Kou, Huizhi published the artcileA new macrocyclic heterobinuclear Cu(II)-Zn(II) complex: synthesis, crystal structure, phosphate hydrolysis, and DNA binding studies, Recommanded Product: N1,N2-Dibenzylethane-1,2-diamine, the publication is Journal of Coordination Chemistry (2019), 72(10), 1683-1696, database is CAplus.
A new macrocyclic heterobinuclear Cu(II)-Zn(II) complex was synthesized and characterized by elemental anal., FTIR, ES-MS, and single-crystal x-ray diffraction. Five-coordinate geometry for the new complex is proposed. The Cu…Zn distance bridged by two phenolic oxygens and a acetate ligand is 2.9508 ?. The phosphate ester hydrolysis activity and the DNA binding ability of the complex were studied. The present complex has an efficient catalytic activity of phosphoester bond cleavage. The catalytic rate constant kcat for the hydrolysis of 4-nitrophenyl phosphate disodium salt hexahydrate (pNPP) by the synthesized complex is 2.69 ¡Á 10-4 s-1 and 105 times faster than the spontaneous hydrolysis of the phosphate monoester. The complex shows a good binding ability to calf thymus (CT-DNA) and the corresponding binding constant is 1.9 ¡Á 105 M-1. The linear Stern-Volmer quenching constant obtained by the fluorescent spectroscopic is 6.3 ¡Á 104 M-1.
