Alkyldihydroxy-p-benzoquinone and related compounds were newly prepared and effects of these compounds on a respiration of rat liver intact mitochondria were examined. Structure activity relationship between the benzoquinone derivatives and effects on the mitochondrial respiration was discussed. 1. 2-Methyl-5-octyl-3, 6-dihydroxy-1, 4-benzoquinone and ardisiaquinone B showed specific inhibition of State-3 respiration. But in high concentration they inhibited both State-3 and State-4 respiration. 2. 2-Octyl-3, 5-diydroxy-1, 4-benzoquinone and ardisiaquinone A inhibited both State-3 and State-4 respiration. 3. Rapanone, maesaquinone, polygonaquinone and related compounds having longer alkyl chains did not show any effect. As the result carbon numbers of the side chain have been found to be an important factor to exhibit the activity.
新制备了烷基二羟基-p-姜黄酮及相关化合物,并研究了这些化合物对大鼠肝脏完整线粒体呼吸的影响。讨论了苯醌衍生物与线粒体呼吸影响之间的结构-活性关系。1. 2-甲基-5-辛基-3, 6-二羟基-1, 4-苯醌和阿尔迪西亚醌B对状态3呼吸表现出特异性抑制,但在高浓度下会抑制状态3和状态4呼吸。2. 2-辛基-3, 5-二羟基-1, 4-苯醌和阿尔迪西亚醌A同时抑制状态3和状态4呼吸。3. 拉帕酮、梅萨醌、Polygonum醌及相关的长烷基链化合物没有表现出任何效果。结果表明,侧链的碳数是表现活性的一个重要因素。
