產品描述
(-)-表沒食子兒茶素沒食子酸酯((-)-Epigallocatechin
Gallate, EGCG),CAS NO. 989-51-5,是從綠茶中提取純化的一種成分,是兒茶素類化合物中最有效的活性成分,具有最強的抗氧化、抗癌、抗突變和抗血管生成活性,已被用于多種腫瘤包括肝癌、胃癌、皮膚癌、乳腺癌和結腸癌等的化學預防研究中,也對許多病毒包括HCV、HIV-1、HSV-1、HSV-2、腺病毒等有抑制作用。EGCG屬于一種天然的多酚黃酮類抗生素,能夠抑制端粒酶(telomerase)和DNA甲基轉移酶(DNA methyltransferase),阻止EGF受體和HER-2受體的激活,也能抑制脂肪酸合成酶和谷氨酸脫氫酶的活性。是一種β-分泌酶抑制劑(IC50=1.6μM),能抑制淀粉樣蛋白的組裝,抑制由蛋白如Aβ,α-突觸核蛋白和亨廷頓蛋白介導的淀粉樣纖維的形成。能抑制細胞生長和選擇性誘導A431和人胰腺癌細胞的凋亡。也是DNMT1抑制劑。

intraperitoneally injected EGCG in diabetic mice: involvement of oxidative
stress, inflammation and apoptosis. Sci Rep. 2017 Jan 18;7:40617. PMID:
28098182
體內研究:
動物模型(Animal Model):Male Swiss albino mice weighing 25–30?g
藥物配制(Preparation):Teavigo, a highly purified extract containing 94% EGCG,
dissolved in saline
注射劑量(Dosages):Mice were randomly divided into 4 groups
8 mice each except group 4 in which 15 mice were used: Group 1 received
saline served as normal control. Group 2 received a single dose of STZ
(150?mg/kg, i.p) used as diabetic control.Group
3 received EGCG (100?mg/kg, i.p) dissolved in saline for 4 days. Group
4 received STZ as in group 2 then the diabetic animals were injected after
48?hrs with EGCG as in group 3. After 48?hrs of STZ injection, animals with
blood glucose level ≥200?mg/dl were selected as diabetic animals.
給藥途徑(Administration):Intraperitoneal (i.p.) injection

體內研究:
動物模型(Animal Model):Eight-week-old male mice that was successfully induced as diabetic
mice.
藥物配制(Preparation):EGCG dissolved in normal saline
注射劑量(Dosages):The diabetic mice and age-matched
controls were treated daily by subcutaneously injected EGCG (100?mg/kg≥98%, dissolved in normal saline) or normal saline daily, for a total
period of 24 weeks. Blood glucose was recorded on days 0, 28, 56, 84, 112,
140, and 168, after diabetes onset.
給藥途徑(Administration):Subcutaneous (s.c.) injection
