一般說明

(−)-表没食子儿茶素没食子酸酯是绿茶中的生物活性成分,占儿茶素总量的50-80%。

應用

(−)-表没食子儿茶素没食子酸酯的应用实例:
  • 检测其作为潜在的神经保护剂,对脊髓损伤和血脊髓屏障(BSCB)渗漏的保护作用
  • 作为抗小鼠视网膜光诱导光感受器变性的有效抗氧化剂
  • 作为治疗视网膜色素变性(RP)的抗氧化药物,可减少氧化损伤和改变色素性杂合P23H大鼠的昼夜节律
  • 检测其对限制性心肌病(RCM)小鼠心室舒张功能障碍的逆转作用
  • 小鼠结直肠癌的抗癌剂

生化/生理作用

(−)-表没食子儿茶素没食子酸酯(EGCG)结构中含有8个羟基(OH),因而决定了它的高抗氧化特性。除了可作为一种有效的游离氧自由基清除剂之外,它还可用作优良的螯合剂和重要转录因子的调节剂,主要是核因子-κβ(NF-kβ)。EGCG已被证明是一种有效的抗肥胖剂,可增强能量消耗和脂肪氧化及减轻人食欲。EGCG也可在缺血和脊髓损伤的初始阶段发挥抗炎和神经保护作用。它可减少小窝蛋白-1表达,维持血脑屏障的完整性和下调促炎细胞因子水平。
