  4'- chloroaurone的合成，结构修饰和生物学活性，它是一种海洋褐藻变种Spatoglossum的代谢产物

  摘要：

  4'-Chloroaurone（1a），是唯一从海洋来源获悉的金盏花，Spatoglossum variabile是由2-羟基苯乙酮与六个结构类似物合成的。所得产物为Z-异构体，并且通过光异构化将其转化为E-异构体。黄金的E和Z异构体表现出明显的质子和碳化学位移。但是，Z -4'-chloroaurone（1a）或它的E-异构体（2a）的光谱数据）与报告的天然产品不匹配，因此需要修改指定的结构。报道的天然产物的质子NMR光谱数据与已知的异香豆素报道的数据相符（5）。评估了合成的E和Z的金黄色元素的抗氧化和抗菌活性。所述金酮Z -2-[（3,4-二羟基苯基）亚甲基]苯并[ b ]呋喃-3-酮具有显着的抗氧化活性。有趣的是，Z-金黄色素对革兰氏阳性和革兰氏阴性细菌有活性，而相应的E-金黄色素是无活性的。

  3,4-Dihydroxychalcones as potent 5-lipoxygenase and cyclooxygenase inhibitors

  摘要：

  A novel series of 3,4-dihydroxychalcones was synthesized to evaluate their effects against 5-lipoxygenase and cyclooxygenase. Almost all compounds exhibited potent inhibitory effects on 5-lipoxygenase with antioxidative effects, and some also inhibited cyclooxygenase. The 2',5'-disubstituted 3,4-dihydroxychalcones with hydroxy or alkoxy groups exhibited optimal inhibition of cyclooxygenase. We found that 2',5'-dimethoxy-3,4-dihydroxychalcone (37; HX-0836) inhibited cyclooxygenase to the same degree as flufenamic acid and 6-lipoxygenase, more than quercetin. Finally, these active inhibitors of 5-lipoxygenase inhibited arachidonic acid-induced mouse ear edema more than phenidone.
