The interaction between glutathione-containing dinitrosyl iron complexes and superoxide radicals has been studied under the conditions of superoxide radical generation in mitochondria and in a model system xanthine-xanthine oxidase. It has been shown that both superoxide radical and hydroxyl radical are involved in the destruction of dinitrosyl iron complexes. At the same time, iron contained in dinitrosyl iron complex, apparently, does not catalyze the decomposition of hydrogen peroxide with the formation of hydroxyl radical. It has been found that dinitrosyl iron complexes with different anion ligands inhibit effectively the formation of phenoxyl probucol radical in a hemin-H2O2 a system. In this process, different components of the dinitrosyl iron complexes take part in the antioxidant action of these complexes. |
