( ) epigallocatechin gallate

(-)-Epigallocatechin Gallate (EGCG) 属于茶类黄酮天然产物，可抑制 EGFR 信号传导，抑制 GLUD 1/2。(-)-Epigallocatechin Gallate 具有抗氧化、抗炎和抗肿瘤活性。(-)-Epigallocatechin Gallate 可以通过激活细胞色素 c 氧化酶来诱导氧化磷酸化。

MST-312 (Telomerase Inhibitor IX) 是绿茶表没食子儿茶素没食子酸酯 (EGCG) 的衍生物。MST-312 是 telomerase 抑制剂，可用于肿瘤的研究，如多发性骨髓瘤 (MM)。

Eicosapentaenoyl Chloride (Eicosapentaenoic acid Chloride; EPA Chloride) 是二十碳五烯酸的衍生物，用于合成脂肪酸缀合物，以提高生物活性化合物如 (–)-表没食子儿茶素没食子酸酯和水杨酸的亲脂性和细胞渗透性。

(-)-Epigallocatechin-3-(3''-O-methyl) gallate ((-)-EGCG-3''-O-ME) 是从茶叶中分离出的一种天然产物，具有很强的抗氧化、细胞毒性和抗菌活性，可增强蚀刻漂洗粘合剂与牙本质的粘合稳定性。

3-O-(E)-p-coumaroyl tormentic acid may be promising lead compound for developing an effective drug for treatment of leukemia, it induces apoptotic cell death in human leukemia (HL60) via mainly mitochondrial pathway by, at least in part, Topo I inhibition. 3-O-trans-p-coumaroyltormentic acid shows cytotoxicity against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15) in vitro, the IC50 values of 13.72, 14.29,14.61, 14.04 uM, respectively. 3beta-O-cis-p-Coumaroyltormentic acid, and 3beta-O-trans-p-coumaroyltormentic acid are weakly selective for vancomycin-resistant Enterococcus (VRE) compared with eukaryotic cells, with an MIC of 59.4microg/mL and a 50% inhibitory concentration (IC50) of 72.0microg/mL for monkey kidney epithelial (MA104) cells. A mixture of 3-O-cis-p-coumaroyltormentic acid and 3-O-trans-p-coumaroyltormentic acid shows an inhibitory effect comparable to (-)-epigallocatechin gallate (EGCG) of green tea on the activation of Epstein-Barr virus early antigen (EBV-EA) induced by 12-O-tetradeca--noylphorbol-13-acetate (TPA).
