Epigallocatechin 3-O-(3-O-methyl)gallate

Description:

Epigallocatechin 3-O-(3-O-methyl)gallate (CAS 83104-87-4) is a polyphenolic compound derived from green tea, specifically a methylated form of epigallocatechin gallate (EGCG). It is characterized by its complex structure, which includes multiple hydroxyl groups contributing to its antioxidant properties. This compound exhibits significant biological activities, including anti-inflammatory, anti-cancer, and cardioprotective effects, largely attributed to its ability to scavenge free radicals and modulate various signaling pathways. Epigallocatechin 3-O-(3-O-methyl)gallate is soluble in organic solvents and has limited solubility in water, which can influence its bioavailability and efficacy in biological systems. Its stability can be affected by factors such as pH and temperature, making it important to consider these conditions in research and application. Overall, this compound represents a valuable area of study in the context of health benefits associated with polyphenols found in tea and other plant sources.

(-)-EGCG-3''-O-ME

CAS: 83104-87-4

(-)-EGCG-3''-O-ME is a methylated derivative of epigallocatechin (EGCg) that has been shown to have hepatoprotective properties. (-)-EGCG-3''-O-ME inhibits the growth of bacterial cells by binding to the proton pump in the bacterial cell membrane and preventing the transport of protons across the membrane, which leads to an accumulation of hydrogen ions inside the bacterial cell. (-)-EGGCg also inhibits alcohol-induced liver injury and is an antioxidant. (-)-EGGCg has been shown to have anti-obesity effects on mice fed a high fat diet, as well as lowering blood pressure in rats. (-)-EGCg can be detected by analytical methods such as gas chromatography or high performance liquid chromatography (HPLC).
