Abstract:
The complex [Cu4(phen)4(H2O)2]·(pyri)·3H2O(where phen=1,10-phenanthroline and pyri=3,5-pyridine dicarboxylic acid)has been synthesized and characterized. IR spectra, elemental analysis and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure of the complex. The binding of the complex with HC-DNA (HeLa cells DNA, which was extracted by ourselves) was investigated by fluorescence spectrum. Gel electrophoresis assay demonstrates the ability of the complex to cleave the extracted HC-DNA. Additionally, the complex exhibited a significant cytotoxic specificity and cancer cell inhibitory rate. The apoptotic tests indicate that the complex have an apoptotic effect on HeLa cells.
