title: Synthesis, structural characterization and antitumor activity evaluations of copper complex with tetraazamacrocyclic ligand.
abstract: Cu (II) complex with 1,4,7,10-tetrakis(2-cyanoethyl-)-1,4,7,10-tetraazacyclododecane was prepared and characterized by X-ray diffraction. Four nitrogen atoms of macrocyclic ligand and oxygen atom of water molecule defined a tetragonal pyramidal polyhedron surrounding the central copper atom. Preliminary pharmacological tests showed that it had antitumor activity against P388 and BEL-7404 cell lines in vitro. Also it exhibited perturbation effects to K562 tumor cell lines at G0-G1 stage and further studies showed that it can cleave supercoiled DNA (pBR 322) to nicked and linear DNA in aerobic condition.
