Cell experiment [1]:

Cell lines

Human and rat neural progenitor cells (NPCs)

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

0, 1, 2, 5 and 10 μM; 24 or 48 hrs


(-)-Epigallocatechin Gallate (EGCG) altered human and rat NPC development in vitro. EGCG affected migration distance, migration pattern and nuclear density of NPCs growing as neurospheres. EGCG exerted these functional impairments by binding to the extracellular matrix (ECM) glycoprotein laminin, preventing its binding to β1-integrin subunits, thereby prohibiting cell adhesion and resulting in altered glia alignment and decreased number of migrating young neurons.

Animal experiment [2]:

Animal models

A rat model of partial bladder outlet obstruction (pBOO)-induced bladder injury

Dosage form

4.5 mg/kg/day; i.p.; 2 days or 30 days


EGCG attenuated bladder inflammation caused by pBOO at the 48th hr. At the 30th day, EGCG attenuated endoplasmic reticulum (ER) stress-related apoptosis. In addition, EGCG improved bladder compliance, contractile frequency and inflammation at the 30th day.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

EGCG prevents cardiac mitochondrial metabolism and apoptosis in CS-exposed rats and exhibits enduring cardio protection at mitochondrial level, where it shelters the activities of TCA cycle enzymes and antioxidant enzymes from CS exposure with concomitant decrease in lipid peroxidation and increase in GSH level, inhibits apoptosis through a series of cellular events, including inhibition of the release of cytochrome c into cytosol, activation of pro-caspase-3, down-regulation of Bax and up-regulation of Bcl-2, and reverses the ultra structural apoptotic alternations of mitochondria and nucleus.
2. The reconstructed skin micronucleus assay in EpiDerm™: reduction of false-positive results - a mechanistic study with epigallocatechin gallate. Mutat Res. 2013 Oct 9;757(2):148-57. doi: 10.1016/j.mrgentox.2013.08.001. Epub 2013 Aug 27.
EGCG, which causes positive results in in vitro mammalian genotoxicity assays via oxidative stress and negative results in in vivo MN studies, was used to assess the effect of cell differentiation status on MN induction and significantly induced the expression of genotoxic response related genes in NHEKs after 12h. The Oxidative stress probably caused by EGCG can be eliminated by EpiDermTM under in vitro experimental conditions.
3. Assessment of DNA damage and lipid peroxidation in diabetic mice: effects of propolis and epigallocatechin gallate (EGCG). Mutat Res. 2013 Sep 18;757(1):36-44. doi: 10.1016/j.mrgentox.2013.04.022. Epub 2013 Jul 13.
EGCG, a strong antioxidant with possible anti-obesity and anti-diabetic effects, was administered intraperitoneally to alloxan-induced diabetic mice at doses of 50mg/kg body weight for a period of 7 days resulting in a significant increase of body weight and haematological/immunological blood parameters, 100% survival, a significant decrease of lipid peroxidation in liver, kidney and brain tissue, and remarkably reduced DNA damage in peripheral lymphocytes. Due to the demonstrated beneficial effects against diabetes and the associated consequences of free-radical formation in kidney, liver, spleen and brain tissues, EGCG could be used as a dietary supplement potentially contributing to nutritional strategies for the prevention and treatment of diabetes mellitus.
4. Epigallocatechin-gallate (EGCG) regulates autophagy in human retinal pigment epithelial cells: a potential role for reducing UVB light-induced retinal damage. Biochem Biophys Res Commun. 2013 Sep 6;438(4):739-45. doi: 10.1016/j.bbrc.2013.07.097. Epub 2013 Jul 31.
EGCG is involved in UVB irradiation-induced autophagy in RPE cells, where the treatment of EGCG significantly reduced the formation of LC3-II and autohagosomes and remarkably relieved UVB irradiation-induced toxicity to RPE cells in an autophagy-dependent manner, and is a potential therapeutic reagent that could be incorporated into the treatment of pathological conditions associated with abnormal autophagy.
5. Green tea epigallocatechin gallate binds to and inhibits respiratory complexes in swelling but not normal rat hepatic mitochondria. Biochem Biophys Res Commun. 2014 Jan 17;443(3):1097-104. doi: 10.1016/j.bbrc.2013.12.110. Epub 2013 Dec 31.
EGCG, which is hepatotoxic to humans and animals, barely affected oxidative phosphorylation at 7.5-100 μΜ in normal mitochondria of rats liver but remarkably inhibited RCCs in mitochondria undergoing Ca(2+) overload-induced MPT only if IM integrity was compromised. EGCG promotes Ca(2+) overload-induced MPT after moderate MPT has already commenced and worsens pre-existing mitochondria abnormalities triggering hepatotoxicity since it only targets hepatic RCCs in swelling mitochondrial other than normal mitochondrial.
