产品介绍
(-)-Epigallocatechin Gallate sulfate (EGCG) 是绿茶中的一种主要多酚,可抑制细胞增殖并诱导细胞凋亡。 (-)-Epigallocatechin Gallate sulfate 可抑制谷氨酸脱氢酶 1/2 (GDH1/2, GLUD1/2) 的活性。(-)-Epigallocatechin Gallate sulfate 对结直肠癌、髓性白血病、甲状腺癌等多种癌症具有有效的抗癌、抗氧化和抗炎特性。
生物活性

(-)-Epigallocatechin Gallate (EGCG) is a major polyphenol in green tea, which can inhibit cell proliferation and induce cellapoptosis. (-)-Epigallocatechin Gallate inhibits glutamate dehydrogenase 1/2 (GDH1/2, GLUD1/2) activity. (-)-Epigallocatechin Gallate has a potent anticancer, antioxidant and anti-inflammatory properties against various types of cancers such as colorectalcancer, myeloid leukemia, thyroid carcinoma[1][2][3][4].

体外研究
(In Vitro)

(-)-Epigallocatechin Gallate (EGCG, 10-60 μM) inhibits the growth of FB-2 and WRO cells in a dose-dependent manner[1].
(-)-Epigallocatechin Gallate (10-60 μM, 0-24 h) reduces cyclin D1 and phosphorylation of AKT and ERK1/2, and increases p21 and p53 expression[1].
(-)-Epigallocatechin Gallate (10-60 μM, 12 h) reduces cell motility and migration[1].
(-)-Epigallocatechin Gallate (0-20 μM, 0-20 min approximately) inhibits GLUD1/2 and IDH1 activity in a concentration and time-dependent way (biochemical assays)[2].
(-)-Epigallocatechin Gallate (0-35 μg/mL, 24-72 h) inhibits the proliferation of colorectal cancer cells (LoVo, SW480, HT-29, HCT-8 cells), increases cell apoptosis and blocks cells at the G0/G1 phase[3].
(-)-Epigallocatechin Gallate (30 μM, 3-24 h) suppresses the expression of COX-2 and mPGES-1 mRNAs, prostaglandin E2 production in LPS-induced osteoblasts[4].

Cell Proliferation Assay[1]

Western Blot Analysis[1]

Cell Line:FB-2 cells
Concentration:10, 40, 60 μM.
Incubation Time:24 h

Cell Migration Assay[1]

Cell Line:FB-2 and WRO cells (serum-starved for 48h)
Concentration:10, 40, 60 μM.
Incubation Time:12 h
Result:Reduced migration activity in FB-2 and WRO cells.

RT-PCR[4]

Cell Line:Mouse primary osteoblasts (1 ng/ml LPS-treated)
Concentration:30 μM
Incubation Time:3, 6, 12, 24 h
Result:Suppressed the LPS-induced expression of COX-2 and mPGES-1 mRNAs, prostaglandin E2 production.
体内研究

(-)-Epigallocatechin Gallate (Intragastrical administration, 5-20 mg/kg, once daily for 14 days, orthotopic transplant model) decreases tumors growth[3].
(-)-Epigallocatechin Gallate (Injected into the mouse lower gingiva, a single dose of 0.5 mg/mouse, experimental periodontitis model) decreases inhibits the LPS-induced loss of bone mineral density (BMD)[3].

Animal Model:Orthotopic transplant BALB/c nude mice model[3]
Dosage:5, 10, and 20 mg/kg, once daily for 14 days.
Administration:Intragastrical administration.

Animal Model:Model of experimental periodontitis, LPS (25 μg/mouse)[4]
Dosage:0.5 mg/mouse, a single dose.
Administration:Injected into the mouse lower gingiva
Result:Inhibited the LPS-induced loss of bone mineral density (BMD) in mice.
