Models for superoxide dismutases: characterization of mononuclear Cu(II), Fe(III), and Mn(II) complexes with 4',5'-bis(salicylideneimino)benzo-15-crown-5.
Mononuclear Cu(II), Fe(III), and Mn(II) complexes with 4',5'-bis (salicylideneimino)benzo-15-crown-5, (SALH2), were characterized by elemental analysis, IR and UV-Vis spectroscopy and tested spectrometrically as catalysts for superoxide disproportionation by utilizing xanthine-xanthine oxidase (XXO) assays. The results indicate that the examined mononuclear complexes are speculative potent superoxide dismutase mimics.
