(-)-Epigallocatechin (also known as EGC; Epigallocatechin; L-Epigallocatechin) is a naturally occurring polyphenol and flavonoid extractied from green tea, which shows multiple bioactivity. (-)-Epigallocatechin 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 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 |
(-)-Epigallocatechin (EGC) is a strong in vitro inhibitor of the development of amyloid cystatin I66Q amyloid fibrils. According to computational study, (-)-epigallocatechin stabilizes the molecule in its original state instead of causing aggregation to reroute into disordered, amorphous aggregates, which prevents the production of amyloid cysteine protease fibrils [1]. The population of cancer stem cell-like cluster of differentiation 44 (CD44)-positive cells was decreased by combination therapy with curcumin and EGCG. Curcumin and (-)-epigallocatechin (EGC) significantly suppressed STAT3 phosphorylation and retained the STAT3-NFkB connection, as demonstrated by Western blot and immunoprecipitation study [2]. (-)-Epigallocatechin (EGC) effectively removes Enterococcus faecalis biofilms, with MIC and MBC values of 5 μg/mL and 20 μg/mL, respectively. Enterococcus faecalis produces hydroxyl radicals when exposed to (-)-epigallocatechin. the DIP-protected E addition. faecalis through the antibacterial actions of EGCG. Enterococcus faecalis virulence genes are significantly downregulated at sub-MIC levels by (-)-epigallocatechin [3].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.16 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% 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 25.0 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: ≥ 2.5 mg/mL (8.16 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 25.0 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.
