| Abstract: | A method is suggested for quantitative assessment of the anti-/prooxidant activity of d-metal cations by their effect of the rate of the reduction of nitrotetrazolium blue to formazan in a system generating the superoxide radical anion in the presence of reduced nicotinamide adenine dinucleotide (NADH2). The effect of the acidity of the medium on the anti/prooxidant activity of cations, as well as correlations between the ionization potentials, ionic radii, and antioxidant properties of cations are analyzed. |
