Показано, что введение N-ацетилцистеина, а также сочетанного назначения его с модуляторами биосинтеза кофермента А (D-пантенолом или D-пантетином) на фоне алюминиевого нейротоксикоза приводят к выраженному снижению продукции активных форм кислорода митохондриями, снижению наработки тиобарби-турат-реагирующих соединений, нормализации содержания глутатиона и его биосинтеза в ткани мозга. Полученные результаты указывают на высокую эффективность предшественника биосинтеза глутатиона N-ацетилцистеина в предупреждении окислительного стресса в хронической модели алюминиевого нейротоксикоза, что может быть обоснованием для его применения как модулятора редокс-статуса митохондрий при развитии нейродегенеративной патологии.</p></abstract><trans-abstract xml:lang="en"><p>Using an experimental model of aluminum neurotoxicosis, it was established that under conditions of chronic administration of aluminum chloride to rats, oxidative stress develops and inhibits the redox potential of the glutathione system in the mitochondrial and postmitochondrial fractions of the cerebral hemispheres. It was shown that the ingestion of N-acetylcysteine, as well as its combined use with coenzyme A biosynthesis precursors (D-panthenol or D-pantetin) against the background of aluminum neurotoxicosis, leads to a marked decrease in the production of reactive oxygen species by mitochondria, a decrease in the production of thiobarbituric acid reactive substances, and normalization of GSH content and its biosynthesis in brain tissue. The results indicate a high efficiency of the biosynthesis precursor of glutathione N-acetylcysteine in the prevention of oxidative stress in the chronic model of aluminum neurotoxicosis, which may be the rationale for its use as a modulator of mitochondrial redox status in the development of neurodegenerative pathology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>окислительный стресс</kwd><kwd>митохондрии</kwd><kwd>алюминиевый нейротоксикоз</kwd><kwd>глутатион</kwd><kwd>N-ацетилцистеин</kwd><kwd>производные пантотеновой кислоты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidative stress</kwd><kwd>mitochondria</kwd><kwd>aluminum neurotoxicosis</kwd><kwd>glutathione</kwd><kwd>N-acetylcysteine</kwd><kwd>pantothenic acid derivatives</kwd><kwd>coenzyme A</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lezi, E.
