  • Syntheses of 3',4'-dihydroxy-5,6,7- and 5,7,8-trioxygenated 3',4'-dihydroxy flavones having alkoxy groups and their inhibitory activities against arachidonate 5-lipoxygenase

    Arachidonate 5-lipoxygenase plays a pivotal role in the biosynthesis of leukotrienes. Cirsiliol (3',4',5-trihydroxy-6,7-dimethoxyflavone), a selective inhibitor of the enzyme, was derivatized by introducing alkyl groups of various chain lengths at positions 5, 6, 7, and 8 of the A ring of the flavone skeleton. Modification of the positions 5 and 6 with an alkyl group of 5-10 carbons markedly decreased
    花生四烯酸5-脂氧合酶在白三烯的生物合成中起关键作用。通过在A环的5、6、7和8位上引入各种链长的烷基,可以衍生化酶的选择性抑制剂Cirsiliol(3',4',5-三羟基-6,7-二甲氧基黄酮)黄酮骨架。用5-10个碳的烷基修饰位置5和6,将5-脂氧合酶抑制作用的IC50值明显降低至10 nM。如用5-或6-己氧基氧基衍生物测试,显示了对5-脂氧合酶的相对选择性的抑制。抑制12-脂氧合酶需要这些化合物的浓度更高,而环氧合酶则没有被抑制。修饰7和8位不会增加大多数黄酮类化合物的抑制作用。
  • Studies of the Selective O-Alkylation and Dealkylation of Flavonoids. XXII. A Convenient Method for Synthesizing 3,5,7-Trihydroxy-6-methoxyflavones.

    The demethylation of 3, 4-dioxygenated 6-methoxy-2-isopropoxyacetophenones was studied and it was found that 4-benzyloxy-6-hydroxy-3-methoxy-2-isopropoxyacetophenone was easily obtained from 4-benzyloxy-3, 6-dimethoxy-2-isopropoxyacetophenone by selective demethylation with anhydrous aluminum bromide-sodium iodide in acetonitrile. The acetophenone was converted into 7-benzyloxy-3-hydroxy-6-methoxy-5-isopropoxyflavones by cyclization followed by oxidation with dimethyldioxirane. The isopropoxy group in the flavones was selectively cleaved with anhydrous aluminum chloride via the corresponding tosylates to give 7-benzyloxy-3, 5-dihydroxy-6-methoxyflavones, which were converted into the desired 3, 5, 7-trihydroxy-6-methoxyflavones by hydrogenolysis. The process was suitable as a general method for synthesizing 3, 5, 7-trihydroxy-6-methoxyflavones and five flavones were synthesized. We also examined the 13C-NMR spectra of twelve kinds of 3, 5, 6, 7-tetraoxygenated 4'-methoxyflavones and revised the proposed structure of a natural flavone.
    研究了3, 4-二氧化6-甲氧基-2-异丙氧基苯乙酮的脱甲基反应,发现4-苄氧基-6-羟基-3-甲氧基-2-异丙氧基苯乙酮很容易由4-苄氧基-3, 6-二甲氧基得到4-苄氧基-6-羟基-3-甲氧基-2-异丙氧基苯乙酮-2-异丙氧基苯乙酮,用无水溴化铝-碘化钠在乙腈中选择性脱甲基。通过环化然后用二甲基二环氧乙烷氧化将苯乙酮转化为7-苄氧基-3-羟基-6-甲氧基-5-异丙氧基黄酮。用无水氯化铝通过相应的甲苯磺酸盐选择性裂解黄酮中的异丙氧基,得到7-苄氧基-3,5-二羟基-6-甲氧基黄酮,将其转化为所需的3,5,7-三羟基-6-甲氧基黄酮通过氢解作用。该工艺适合作为合成3,5,7-三羟基-6-甲氧基黄酮的通用方法,并合成了5种黄酮。我们还检查了 12 种 3,5,6,7-四氧化 4'-甲氧基黄酮的 13C-NMR 谱,并修改了天然黄酮的提议结构。
