In order to study the structure activity relationship of metabolites of ubiquinone, α-tocopherol and phylloquinone (Ia, b, c, IIa, b, c), 3-carboxy-2-butenyl (IIIa, b, c), 6-hydroxy-3-methyl-2-hexenyl (IVa, b, c), 4-hydroxy-3-methylbutyl (Va, b), 4-hydroxy-3-methyl-2-butenyl (VIb, c), ω-carboxyalkyl (VIIa, b, c), and ω-hydroxyalkyl (VIIIa, b) side chains were introduced into the 6-position of 2, 3-dimethoxy-5-methyl-1, 4-benzoquinone and 2, 3, 5-trimethyl-1, 4-benzoquinone, as well as the 3-position of 2-methyl-1, 4-naphthoquinone. The effects of these quinones on the membrane stability of rat-liver lysosomes and on the activity of bovine heart phosphodiesterase were investigated. A good correlation was observed between these activities of the benzoquinone derivatives (VIIa, b).
为了研究辅酶Q、α-生育酚和叶绿醌(Ia, b, c, IIa, b, c)的代谢产物结构活性关系,将3-羧基-2-丁烯基(IIIa, b, c)、6-羟基-3-甲基-2-己烯基(IVa, b, c)、4-羟基-3-甲基丁基(Va, b)、4-羟基-3-甲基-2-丁烯基(VIb, c)、ω-羧基烷基(VIIa, b, c)和ω-羟基烷基(VIIIa, b)侧链引入到2, 3-二甲氧基-5-甲基-1, 4-苯醌和2, 3, 5-三甲基-1, 4-苯醌的6-位以及2-甲基-1, 4-萘醌的3-位。研究了这些醌类化合物对大鼠肝脏溶酶体膜稳定性和牛心磷酸二酯酶活性的影响。苯醌衍生物(VIIa, b)的这些活性之间观察到了良好的相关性。
