Copper(II) complexes of diclofenac with interesting anti-inflammatory profiles have been prepared and studied by infrared and electronic spectroscopy. In the solid state and in polar and coordinating solvents, all the complexes are solvated binuclear carboxylato-bridged complexes, [Cu(L)(2)(S)](2), where L is monodeprotonatee diclofenac and S is the axially bonded solvent. The effect of the copper(II) complexes on the in vitro DNA strand breakeage was studied by agarose gel electrophoresis. Relaxation or double stranded scissions of pDNA were observed leading to the formation of linear pDNA. Treatment of pDNA with high concentrations of these compounds caused a disappearance of pDNA. For the parent drug, sodium diclofenac, no effect on the pDNA was observed. This study presents some indications that the binuclear copper(II) complexes, [Cu(L)(2)(S)](2), could have some relevance in the treatment of tumor cell lines. (EN)
