(-)-Epigallocatechin Gallate

(-)-Epigallocatechin Gallate
(-)-Epigallocatechin Gallate (EGCG) is a phenolic antioxidant polyphenol flavonoid found in plants such as green and black tea, which inhibits telomerase and DNA methyltransferase, blocks the activation of EGF receptors and HER-2 receptors, inhibits cellular oxidation, and prevents free radical damage to cells.

Product Introduction

Bioactivity
Description
(-)-Epigallocatechin Gallate (EGCG) is a phenolic antioxidant polyphenol flavonoid found in plants such as green and black tea, which inhibits telomerase and DNA methyltransferase, blocks the activation of EGF receptors and HER-2 receptors, inhibits cellular oxidation, and prevents free radical damage to cells.
In vivo
Epigallocatechol Gallate (5 and 20 mg/kg, p.o.) inhibits the growth of tumor in the subcutaneous orthotopic transplant model[4].
Cell Research
LoVo, SW480, HCT-8, and HT-29 cells are seeded in 96-well plates at a concentration of 5×103?cells; each cell line is totally seeded in the 12 wells. Complete medium is added to the wells, up to 200 μL; the medium contains 0 μg/mL, 10 μg/mL, 20 μg/mL, and 35 μg/mL of epigallocatechol gallate. The inhibition rate=[1 - (absorbance of Epigallocatechol Gallate group - absorbance of control group)/(absorbance of control group - absorbance of blank control group)] × 100.
AliasEpigallocatechol Gallate, EGCG

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
