  Antiproliferative and apoptosis-inducing activities of alkyl gallate and gallamide derivatives related to (−)-epigallocatechin gallate

  摘要：

  Green tea and (-)-epigallocatechin gallate (EGCG: one of the main components of green tea) are reported to have cancer-preventive activity in humans. A previous SAR study of EGCG and derivatives indicated that a galloyl group is essential for the activity. To test this hypothesis, we synthesized various alkyl gallate and gallamide derivatives and evaluated their antiproliferative effects on human leukemia HL-60 cells. Dodecyl 3,4,5-trihydroxybenzoate (6c) showed the most potent activity, being more potent than EGCG. To clarify the molecular mechanism of the antiproliferative action, we investigated the effects of 6c on various factors. Compound 6c was found to induce apoptosis mediated by endoplasmic reticulum (ER)-stress-related caspase-12. Upregulation of gadd-153, an ER-stress marker protein, was also observed. These results indicate that 6c induced apoptosis via the ER-stress-related pathway. (C) 2008 Elsevier Ltd. All rights reserved.

  The synthesis and antioxidant efficiencies of amphiphilic gallic acid derivatives are reported. To specify the impact of chemical structure on the antioxidant efficiency, several structural modifications of gallic acid were performed. The following structural features were chosen: i) introduction of hydrophobic or hydrophilic residues on the gallic acid and the type of their linkage, ii) the hydrophilic

  报道了两亲没食子酸衍生物的合成和抗氧化剂效率。为了说明化学结构对抗氧化剂效率的影响，对没食子酸进行了几种结构修饰。选择了以下结构特征：i）在没食子酸上引入疏水或亲水残基以及它们的连接类型，ii）整个分子的亲水性和/或亲脂性。所制备的不同系列的理化研究表明，该多酚的抗氧化效率明显取决于与亲水和疏水部分的连接性质。始终需要推挽效应，酯或酰胺键似乎很适合提高抗氧化剂的效率。第二，观察到在所施加的氧化条件下，亲水性和/或亲脂性极大地影响了没食子酸衍生物的抗氧化活性。获得的结果与极性悖论相符，疏水性衍生物抑制了水相中的氧化，而亲水性产品则无效。
