  摘要：

  合成了一系列肉桂酸衍生物，酰胺（1-12）和酯（13-22），并建立了抗氧化活性与单胺氧化酶（MAO）A和B，乙酰胆碱酯酶和丁酰胆碱酯酶（BChE）的构效关系。分析抑制活性。在合成的化合物中，化合物1-10、12-18和迷迭香酸（23）含有邻苯二酚，邻甲氧基苯酚或5-羟基吲哚部分，它们显示出有效的1,1-二苯基-2-吡啶并肼基（DPPH）自由基清除活动。化合物9-11、15、17-22显示出有效和选择性的MAO-B抑制活性。化合物20是最有效的MAO-B抑制剂。化合物18和21显示出中等的BChE抑制活性。另外，化合物18显示出有效的抗氧化剂活性和MAO-B抑制活性。在肉桂酸酰胺和酯的比较中，酰胺表现出更强的DPPH自由基清除活性，而酯显示出对MAO-B和BChE的较强抑制活性。这些结果表明，肉桂酸衍生物，例如化合物18，对香豆酸3,4-二羟基苯乙基酯，和化合物20，对香豆酸苯乙酯，可以用

• Analogues of N-hydroxycinnamoylphenalkylamides as inhibitors of human melanocyte-tyrosinase

  Melanin play a major role in human skin protection and their biosynthesis is vital. Due to their color, they contribute to the skin pigmentation. Tyrosinase is a key enzyme involved in the first stage of melanin synthesis, catalyzing the transformation of tyrosine to L-dopaquinone. The aim of the present study was to study molecules able to inhibit melanin synthesis through inhibition of tyrosinase and their potential use in treating pigmentation-related disorders. We targeted amides obtained from coupling p-hydroxycinnamic acid derivatives with phenylalkylamines. The biological activity was evaluated on human melanocytes by an assay which measures tyrosine-catalyzed L-Dopa oxidation. The most active amides were: trans-N-caffeoyltyramine, N-dihydrocaffeoyltyramine, and trans-N-dihydro-p-hydroxycinnamoyltyramine which induce complete inhibition at 0.1 mM. At the latter concentration, kojic acid, which was used as the reference inhibitor, was inactive. (C) 2006 Elsevier Ltd. All rights reserved.
