Abstract

A new CuII complex Cunaphvalphen naphval = Schiff base derived from 2hydroxy1naphthaldehyde and lvaline phen = 110phenanthroline has been synthesized and characterized by physicochemical methods The crystal structure of the complex showed that there are four independent molecular structures in the crystallographic asymmetric unit and each of them shows a distorted squarepyramidal CuN3O2 coordination geometry In the crystal the π − π stacking and intermolecular hydrogen bonds form a 2D network The interactions between the CuII complex and calf thymus DNA CTDNA have been studied by spectroscopic methods as well as viscosity and thermal denaturation measurements The results indicate that the CuII complex binds to CTDNA in an intercalative mode The cleavage reaction on pBR322 plasmid DNA has been investigated by agarose gel electrophoresis in the absence and presence of mercaptopropionic acid The CuII complex exhibits an efficient DNA cleavage activity
