  α-Glucosidase inhibition of 6-hydroxyflavones. Part 3: Synthesis and evaluation of 2,3,4-trihydroxybenzoyl-containing flavonoid analogs and 6-aminoflavones as α-glucosidase inhibitors

  摘要：

  The SAR studies suggested that the C-ring of baicalein (1) was not necessary for the activity, and validated the importance of 2,3,4-trihydroxybenzoyl structure of 1. Thus, a series of 2,3,4-trihydroxybenzoyi-containing flavonoid analogs were investigated for the alpha-glucosidase inhibitory activity. The results indicated that 5,6,7-trihydroxy-2-phenyl-4-quinolone (2) and 5,6,7-trihydroxyflavanone (4) showed the comparable activity to 1, while 3,5,6,7-tetrahydroxyflavone (7), 5,6,7-trihydroxyisoflavone (8), and 6-hydroxygenistein (9) showed moderate alpha-glucosidase inhibitory activity. In addition, it was found that 6-amino-5,7-dihydroxyflavone (16) was a more potent and specific rat intestinal alpha-glucosidase inhibitor than 1, and showed the comparable activity to acarbose. This is the first report on mammalian intestinal alpha-glucosidase inhibitory activity of 6-aminoflavones. Kinetic studies revealed that 16 inhibited both sucrose- and maltose-hydrolyzing activities of rat intestinal alpha-glucosidase uncompetitively/ (C) 2004 Elsevier Ltd. All rights reserved.

  Amyloids are known to be modified by natural polyphenols via amination. This study investigates the oxidative coupling mechanisms between polyphenols and N-nucleophiles, using in vitro and in silico approaches. It is shown that polyphenols with a pyrogallol substructure and an electron-withdrawing group at the C4a-position are most effective. These insights can play a crucial role in drug design against

  已知淀粉样蛋白可通过胺化作用被天然多酚修饰。本研究采用体外和计算机方法研究了多酚和N -亲核试剂之间的氧化偶联机制。结果表明，具有连苯三酚亚结构和 C4a 位吸电子基团的多酚最有效。这些见解可以在抗淀粉样蛋白生成的药物设计中发挥至关重要的作用。
