产品说明

一般描述

(−)-表没食子儿茶素没食子酸酯(来源于绿茶)是绿茶中的主要生物活性成分,占儿茶素总含量的50-80%。它的化学结构类似于表儿茶素没食子酸酯(ECG)——没食子酸和表没食子儿茶素形成的酯类物质。

应用

(-)-表没食子儿茶素没食子酸酯已被用于:

  • 作为小鼠TRAMP转移性前列腺细胞系的抗肿瘤剂,用于细胞增殖试验、凋亡检测和改良型Boyden-chamber试验
  • 通过死亡相关蛋白激酶-2途径诱导急性髓细胞白血病细胞死亡,用于细胞活力、细胞周期和凋亡分析
  • 作为小鼠前破骨细胞系RAW264.7的破骨细胞分化的抑制剂
  • 促进成肌细胞分化

包装

50 mg in poly bottle

生化/生理作用

(-)-表没食子儿茶素没食子酸酯 (EGCG)是一种抗氧化多酚类黄酮化合物,它通过抑制端粒酶和DNA甲基转移酶活性而发挥抗肿瘤作用。EGCG可抑制基质金属蛋白酶-2(MMP-2)、MMP-9的表达并降低肿瘤的侵袭能力。EGCG可阻断表皮生长因子(EGF)受体和人表皮生长因子受体-2(HER-2)的活化。EGCG可增加骨矿物质密度并减少骨吸收。EGCG通过抑制核因子κ-B受体活化因子配体(RANKL)诱导的核因子 κ B(NF-κB)转录活性,进而抑制破骨细胞生成。EGCG可减少骨骼肌萎缩。EGCG具有抗衰老性,可增加成肌细胞分化。EGCG可抑制脂肪酸合成酶和谷氨酸脱氢酶活性。

  • 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

包装

100 mg in poly bottle

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。

324880Sigma-Aldrich(–)-Epigallocatechin Gallate-CAS 989-51-5-CalbiochemOne of the main polyphenolic constituents of green tea that exhibits potent antitumor, anti-inflammatory, and antioxidant properties.941.52元/10 MG;   展开

产品说明

一般描述

One of the main polyphenolic constituents of green tea that possesses potent antitumor, anti-inflammatory, and antioxidant properties. EGCG has been shown to inhibit PMA-induced skin thickening, activation of protein kinase C, activation of ornithine decarboxylase, and activation of interleukin-1α mRNA and protein expression. Has also been shown to inhibit inducible nitric oxide synthase (iNOS) gene expression and enzyme activity and to inhibit the peroxynitrite-mediated formation of 8-oxodeoxyguanosine and 3-nitrotyrosine. Also strongly and directly inhibits telomerase. Acts as a selective and noncompetitive inhibitor of HAT activities (IC50 = 30, 50, 60 and 70 µM for p300, CBP, PCAF and TIP60) with minimal effects on HDAC, SIRT and HMTase.
One of the main polyphenolic constituents of green tea that exhibits potent antitumor, anti-inflammatory, and antioxidant properties. Arrests cell cycling at G0/G1 phase and induces apoptosis in a dose-dependent manner. Shown to inhibit PMA-induced skin thickening and to activate of protein kinase C. Also activates ornithine decarboxylase and interleukin-1α mRNA and protein expression. Acts as an inhibitor of inducible nitric oxide synthase (iNOS) gene expression and enzyme activity. Also blocks peroxynitrite-mediated formation of 8-oxodeoxyguanosine and 3-nitrotyrosine. Strongly and directly inhibits telomerase in cell-free systems and in cancer cell lines. An inhibitor of Dnmt1 (IC50 = 210-470 nM). Acts as a selective and noncompetitive inhibitor of HAT activities (IC50 = 30, 50, 60 and 70 µM for p300, CBP, PCAF and TIP60) with minimal effects on HDAC, SIRT and HMTase.
