摘要:
[Zn(L)(CH3OH)(3)] (H2L = N-(1-phenyl-3-methyl-4-propenylidene-5-pyrazolone)-salicylidene hydrazide) has been synthesized by the reaction of zinc nitrate and ligand H2L. The complex crystallizes in orthorhombic system, space group Pbca with a = 5.888(15), b = 14.564(14), c = 22.20(2) angstrom, V= 5137(8) angstrom(3), Z = 8 and F(000) = 2184. The ligand serves as a negative bivalent tridentate chelating agent to coordinate with the central zinc(II) atom. DNA-binding was studied by UV-Vis spectral analysis and ethidium bromide (EB) displacement experiments. The results showed that the DNA-binding constant of the complex is 5.1 X 10(4) M-1. Antitumor activity of [Zn(L)(CH3OH)(3)] and the ligand have been investigated by MTT assay, which indicated that the complex has better cytotoxicity to Eca-109 and HeLa than free ligand.
