Abstract
In this work, two new Cu-based complexes (Complex 1 = Cu2(dcbpy)2·(H2O)2]·2H2O and Complex 2 = Cu5(dpa)2·(H2O)6]·12.4H2O) were synthesized by hydrothermal method. X-ray single crystal diffraction was used to determine the structure of complexes and characterized them by PXRD, infrared, thermogravimetric analysis, XPS, etc. The binding ability of the complexes to DNA was studied by UV and fluorescence spectroscopy, and both complexes showed good binding ability with binding constants of 0.0584 and 0.0311 M−1 respectively. The capability of the complexes to cleave DNA was assessed through gel electrophoresis, and both were found to be effective in cutting DNA. In addition, flow cytometry, inverted microscopy and morphological studies have also proved that the complexes can induce apoptosis. Molecular simulation docking calculations revealed that the bonding energies of the two complexes were −7.71 and −5.25 kcal/mol respectively. In all experiments, complex 1 exhibited better performance. In all experiments, complex 1 showed better performance. It provides potential candidate materials for the development of novel Cu-based complex anticancer drugs.
期刊介绍:
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
