Abstract

Effects of methyltriclosan, a biodegradation product of the antimicrobial agent triclosan, on the functional parameters of rat liver mitochondria were studied. It was found that methyltriclosan inhibits the activity of complexes II and IV of the respiratory chain. This causes a decrease in the rate of oxygen consumption by mitochondria in states 3 and 3UDNP. Methyltriclosan was shown to increase the rate of hydrogen peroxide production by rat liver mitochondria. In addition, methyltriclosan induces permeabilization of both mitochondrial membranes and the liposome membranes. Methyltriclosan, in contrast to triclosan, has a milder effect on organelles and their membranes. Possible mechanisms of methyltriclosan effects on mitochondria and liposomes are discussed.

甲基三氯生对离体大鼠肝线粒体功能及脂质体膜通透性的影响
研究了抗菌药物三氯生的生物降解产物甲基三氯生对大鼠肝脏线粒体功能参数的影响。发现甲基三氯生抑制呼吸链复合体II和IV的活性。这导致线粒体在状态3和3UDNP下的耗氧量下降。甲基三氯生被证明可以增加大鼠肝脏线粒体过氧化氢的生成速率。此外,甲基三氯生诱导线粒体膜和脂质体膜的通透性。与三氯生相比,甲基三氯生对细胞器及其膜的影响较轻。讨论了甲基三氯生影响线粒体和脂质体的可能机制。

期刊介绍: Biochemistry (Moscow), Supplement Series A: Membrane and Cell Biology   is an international peer reviewed journal that publishes original articles on physical, chemical, and molecular mechanisms that underlie basic properties of biological membranes and mediate membrane-related cellular functions. The primary topics of the journal are membrane structure, mechanisms of membrane transport, bioenergetics and photobiology, intracellular signaling as well as membrane aspects of cell biology, immunology, and medicine. The journal is multidisciplinary and gives preference to those articles that employ a variety of experimental approaches, basically in biophysics but also in biochemistry, cytology, and molecular biology. The journal publishes articles that strive for unveiling membrane and cellular functions through innovative theoretical models and computer simulations.
