(-)-Epigallocatechin Gallate (also known as EGCG; epigallocatechin-3-gallate) is a naturally occurring catechin extractied from green tea, which shows multiple bioactivity. (-)-Epigallocatechin gallate functions as a powerful antioxidant, preventing oxidative damage in healthy cells, but also as an antiangiogenic and antitumor agent and as a modulator of tumor cell response to chemotherapy. (-)-Epigallocatechin gallate shows multiple anticancer effects, such as anti-proliferation, anti-angiogenesis, transformation prevention of various cancer cells, cancer cell cycle arrest and inhibition of tumor metastasis.

ln Vitro |
In a dose-dependent manner, (-)-Epigallocatechin Gallate (EGCG, 10-60 μM) suppresses the development of WRO and FB-2 cells [1]. (-)-Epigallocatechin Gallate (10–60 μM, 0–24 h) raises the expression of p21 and p53 and decreases the phosphorylation of cyclin D1, AKT, and ERK1/2 [1]. The effects of (10–60 μM, 12 hours)-Epigallocatechin Gallate on cell motility and migration are reported [1]. According to a biochemical experiment, (-)-Epigallocatechin Gallate (0 – 20 μM, or roughly 0 – 20 minutes) suppresses GLUD1/2 and IDH1 activities in a concentration- and time-dependent manner [2]. (-)- Epigallocatechin Gallate (0-35 μg/mL, 24-72 hours) promotes cell apoptosis, reduces G0/G1 phase cell proliferation, and suppresses the proliferation of colorectal cancer cells (LoVo, SW480, HT-29, and HCT-8 cells)[3]. In osteoblasts, LPS-induced COX-2 and mPGES-1 mRNA expression as well as prostaglandin E2 synthesis are inhibited by (-)-Epigallocatechin Gallate (30 μM, 3–24 h) [4].

ln Vivo |
(-)- Epigallocatechin Gallate inhibits the growth of tumors when given intraperitoneally (5–20 mg/kg) once day for 14 days in an orthotopic transplantation paradigm [3]. (-)- The LPS-induced loss of bone mineral density (BMD) is inhibited and reduced when epigallocatechin gallate is injected into the lower gums of mice in an experimental periodontitis model at a single dose of 0.5 mg/mouse [3].

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.54 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
