  Equol Inhibits Mushroom Tyrosinase <i>in Vitro</i> through Tight Binding

  摘要：

  与其他抑制剂（染料木素和曲酸）相比，赤藓糖醇（一种染料木素的肠道代谢物）在体外对蘑菇酪氨酸酶的抑制作用更强。我们研究了赤藓糖醇抑制酪氨酸酶的机制。用酪氨酸酶处理外消旋赤藓糖醇可产生 3ʹ-羟基赤藓糖醇。由于该产物的光学活性显示对映体过量<25%，因此该反应的立体特异性不高。通过使用抗曲醇单克隆抗体进行酶联免疫吸附试验，我们观察到曲醇与预包被的酪氨酸酶的结合具有剂量依赖性。我们的研究结果表明，等醇与酪氨酸酶形成了稳定的复合物。

• Synthesis of Various Kinds of Isoflavones, Isoflavanes, and Biphenyl-Ketones and Their 1,1-Diphenyl-2-picrylhydrazyl Radical-Scavenging Activities
  作者：Hideyuki Goto、Yoshiyasu Terao、Shuji Akai

  DOI：10.1248/cpb.57.346

  日期：——

  Forty-eight kinds of isoflavones (8), thirty-one isoflavanes (9), and forty-seven biphenyl-ketones (10, 10′) were synthesized from eleven kinds of substituted phenols (11) and six phenylacetic acids (12). Among them, seventy-five compounds are new. The radical scavenging activities of these compounds were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) at pH 6.0. We found that thirty-nine out of forty-three compounds having a catechol moiety on either the A- or the B-ring exhibited a high activity (ED50=12—54 μM) similar to that of catechin. In these cases, the remaining part of their structure seemed to have little effect on their activity. Many 6- or 8-hydroxyisoflavanes (9E—I) and their biphenyl-ketone derivatives (10E—H) also showed a high activity (ED50=<50 μM), while all of their corresponding isoflavones (8E—I) were not active at all. The 7-hydroxyisoflavanes having either an additional hydroxyl group at the C5-position (9D) or a methoxy group at the C6-position (9J) presented a high activity (ED50=26—32 μM). This study suggests that natural isoflavones have the possibilities of exhibiting antioxidant activities through the hydroxylation at the C6-, C8-, or C3′-position or the formation of the isoflavanes (9) and/or the biphenyl-ketone derivatives (10′) by metabolism or biotransformation.

  合成了四十八种异黄酮（8）、三十一种异黄烷（9）以及四十七种联苯酮（10, 10′），这些化合物是由十一种取代酚（11）和六种苯乙酸（12）合成的。其中，有七十五种化合物是新发现的。这些化合物的自由基清除活性在pH 6.0下使用1,1-二苯基-2-吡唑啉酮（DPPH）进行了评估。我们发现，在四十三种含有儿茶酚基的化合物中，三十九种在A环或B环上表现出与儿茶素相似的高活性（ED50=12—54 μM）。在这些情况下，它们结构的其他部分似乎对活性影响不大。许多6-或8-羟基异黄烷（9E—I）及其联苯酮衍生物（10E—H）也显示出高活性（ED50=<50 μM），而它们对应的异黄酮（8E—I）则完全没有活性。具有在C5位增加羟基（9D）或在C6位增加甲氧基（9J）的7-羟基异黄烷则展现出高活性（ED50=26—32 μM）。本研究表明，天然异黄酮通过在C6、C8或C3′位置的羟基化，或通过代谢或生物转化形成异黄烷（9）和/或联苯酮衍生物（10′），具有表现抗氧化活性的可能性。

  日期：2008.4

  A concise strategy is developed for the synthesis of isoflavans employing a Diels-Alder reaction between o-quinone methides and aryl-substituted enol ethers followed by reductive cleavage of the acetal group. The method is extended towards the total syntheses of equol, 3'-hydroxyequol and vestitol. (C) 2008 Elsevier Ltd. All rights reserved.
