   <abstract xml:lang="ru">
    <p>Динитрозильные комплексы железа (ДНКЖ) являются важными метаболитами оксида азота (NO), обладающими широким спектром биологической активности. Свойства этих комплексов определяют не только NO-лиганды, но и другие компоненты, входящие в их состав. С помощью спектроскопии ЭПР было показано, что железо в ДНКЖ может быть связано с карнозином, L-эрготионеином и аденозиндифосфатом (АДФ). Установлено, что наиболее эффективно новые варианты динитрозильных комплексов железа образуются с участием нитроксильного аниона, который является продуктом одноэлектронного восстановления NO. В модельных системах показано, что ДНКЖ связанные с карнозином и эрготионеином снижают уровень различных свободных радикалов. В частности, эти варианты ДНКЖ перехватывают супероксидный анион-радикал, который является предшественником других активных форм кислорода и азота. Вместе с тем, ДНКЖ связанные с карнозином уменьшают концентрацию органических свободных радикалов в системе содержащей нитроксильный анион, ионы железа и гидропероксид трет-бутила. С другой стороны, ДНКЖ связанные с эрготионеином и АДФ могут играть важную роль в защите митохондрий. Можно предположить, что новые варианты ДНКЖ являются компонентами антиоксидантных систем, локализованных в различных тканях организма. Также, они могут функционировать в качестве редокс-зависимых переключателей, регулирующих ответ клетки на окислительный стресс.</p>

    <p>Dinitrosyl iron complexes (DNICs) are important metabolites of nitric oxide (NO) with a wide range of biological activity. The properties of these complexes are determined not only by NO-ligands, but also by other components included in their composition. Using EPR spectroscopy, it was shown that iron in the DNICs can be bound to carnosine, L-ergothioneine and ADP. New variants of DNICs are formed with the participation of a nitroxyl anion, which is a product of one-electron reduction of NO. In model systems, DNICs associated with carnosine and ergothioneine reduce the level of various free radicals. These DNICs intercept the superoxide anion radical, which is a precursor to other reactive oxygen and nitrogen species. At the same time, carnosine-bound DNICs reduce the concentration of organic free radicals in a system containing a nitroxyl anion, iron ions and tert-butyl hydroperoxide. On the other hand, DNICs associated with ergothioneine and ADP may play an important role in the protection of mitochondria. It has been suggested that the new DNICs may be components of antioxidant systems localized in various tissues of the body, as well as redox triggers regulating the cellular response to oxidative stress.</p>
