What is Strong protective action of Copper(II) N-substituted sulfonamide complexes against reactive oxygen species about?
Copper(II) complexes of (3) with interesting protective properties against superoxide radicals have been prepared. The compounds have been characterized by X-ray diffraction and their chemical properties have been studied by spectroscopic methods. The crystal structure of 1 shows that the copper(II) is surrounded by two benzothiazole N atoms from the sulfonamide ligands and two O atoms from the dimethylsulfoxide molecules in a square planar arrangement. The coordination polyhedron around copper(II) in 2 and 3 is distorted square pyramidal being the metal ion linked to benzothiazole N and sulfonamidate O atoms of the ligand and to two dimethylsulfoxide O atoms. The three complexes have a strong protective action over Dsod1 mutant of Saccharomyces cerevisiae against reactive oxygen radicals derived from respiration and against those generated by hydrogen peroxide and menadione.
