   <abstract xml:lang="ru">
    <p>В работе рассматривается влияние растительного тритерпеноида бетулина и его производного бетулоновой кислоты на митохондрии печени крыс. Установлено, что бетулоновая кислота и, в меньшей степени, бетулин активируют митохондриальное дыхание в состояниях 2 и 4 и ингибируют дыхание, стимулированное ADP и ДНФ. В этом случае эффект бетулоновой кислоты приводит к значительному снижению дыхательного контроля и коэффициента АДФ/О, а также к снижению мембранного потенциала. Эффекты обоих соединений были наиболее выражены в случае использования сукцината как субстрата дыхания. Установлено, что действие указанных агентов на функциональные показатели органелл обусловлено как протонофорным эффектом бетулоновой кислоты, так и ингибированием комплексов дыхательной цепи обоими соединениями. Оба агента также достоверно усиливали генерацию H2O2 в митохондриях, окисляющих сукцинат, в то время как бетулоновая кислота оказывала антиоксидантное действие в присутствии НАД-зависимых субстратов. Было также обнаружено, что бетулин индуцирует митохондриальную агрегацию. Бетулоновая кислота гораздо менее эффективно индуцировала агрегацию митохондрий. Обсуждаются возможные механизмы влияния бетулина и бетулоновой кислоты на функционирование митохондрий печени крысы.</p>

    <p>The effect of plant triterpenoid betulin and its derivative betulonic acid on rat mitochondria is considered. It was found that betulonic acid and, to a lesser extent, betulin activate mitochondrial respiration in states 2 and 4 and inhibit respiration stimulated by ADP and DNP. In this case, the effect of betulonic acid leads to a significant decrease in respiratory control and the ADP/O coefficient, as well as to a decrease in membrane potential. The effects of both compounds were most pronounced when succinate was used as a respiratory substrate. It was established that the effect of these agents on the functional parameters of organelles is due to both the protonophore effect of betulonic acid and the inhibition of respiratory chain complexes by both compounds. Both agents also significantly enhanced the generation of H2O2 in succinate oxidizing mitochondria, while betulonic acid exerted an antioxidant effect in the presence of NAD-dependent substrates. It was also found that betulin induces mitochondrial aggregation. Betulonic acid was much less effective in this case. Possible mechanisms of the effect of betulin and betulonic acid on the functioning of rat liver mitochondria are discussed.</p>
