一般描述

(−)-儿茶素没食子酸酯属于多酚类化合物,是绿茶中的儿茶素在热处理时发生差向异构化时形成的。它是一种天然的黄烷醇儿茶素,含有没食子酰部分。

应用

(−)-儿茶素没食子酸酯用于:
  • 检测含有没食子酰部分的儿茶素在抑制人类免疫缺陷病毒-1(HIV-1)整合酶活性方面的效力
  • 分析 Pseudopiptadenia contorta 和商用白坚木栲胶在单纯疱疹病毒 1 型株中的抗氧化和抗病毒特性(耐阿昔洛韦)
  • 研究多酚对人类精子生物化学的影响以及其在配子保存中使用的相关限制

生化/生理作用

(−)-儿茶素没食子酸酯可抑制大鼠脂肪细胞吸收葡萄糖。据报道,它还具有抗氧化特性,并能够降低血浆胆固醇水平。(−)-儿茶素没食子酸酯表现出了改变抗生素抗药性药剂的效力。
绿茶的抗氧化成分。在μM级浓度下,它能够抑制VEGF诱导的酪氨酸磷酸化。它还可以抑制芳香化酶活性,这种酶将雄激素转化为雌激素,并被认为在乳腺癌的病因中发挥作用。
