(-)-Epigallocatechin is a polyphenolic compound, which is a type of catechin, primarily found in the tea plant, Camellia sinensis. This compound is abundant in green tea leaves and is recognized for its potent antioxidant properties. The source of (-)-Epigallocatechin can be traced back to the biosynthesis pathway in plants, where it contributes to the plant's defense mechanisms against environmental stressors. The mode of action of (-)-Epigallocatechin involves the neutralization of free radicals, thereby protecting cells from oxidative damage. It scavenges reactive oxygen species (ROS) and chelates metal ions, thereby preventing the formation of reactive entities that initiate inflammation and DNA damage. This activity makes it a compound of interest in various scientific studies aiming to understand its biochemical and molecular impacts on human health. The uses and applications of (-)-Epigallocatechin are diverse, primarily studied for its potential benefits in reducing the risk of chronic diseases such as cardiovascular diseases, certain cancers, and neurodegenerative disorders. It is also explored for its anti-inflammatory, antiviral, and antimicrobial properties. Research continues to explore its role in modulating signal transduction pathways, cell cycle regulation, and apoptosis in various cell types, highlighting its significance in the field of medicinal chemistry and therapeutic development.
