در این پژوهش آثار پروپیل گالات که از فعالیت اکسیداز انتهایی پلاستید دخیل در تنفس کلروپلاستی جلوگیری می¬کند، بر کارایی فتوسیستم ii در جلبک سبز تک سلولی dunaliella salina با استفاده از اندازه¬گیری کینتیک فلوئورسنس کلروفیل a مطالعه شده است. تیمار کشتهای جلبکی با غلظتهای 1/0، 5/0، 1، 2 و 4 میلی¬مولار پروپیل گالات نشان داد که کارایی فتوسیستم ii در حضور غلظتهای تا 1 میلی¬مولار افزایش یافته...
Epigallocatechin gallate (EGCG) is the most abundant component of green tea catechins and has strong physiological activities. In this study, two novel EGCG glycosides (EGCG-G1 and EGCG-G2) were chemoselectively synthesized by a chemical modification strategy. Each of these EGCG glycosides underwent structure identification, and the structures were assigned as follows: epigallocatechin gallate-...
Background and Aims: Epigallocatechin-3-gallate (EGCG) is a polyphenolic compound from green tea, which its anticancer effects on many types of cancers have been confirmed, but the molecular mechanism by which EGCG induces apoptosis remains unknown. The aim of the present study was to investigate anti-proliferative properties and apoptotic signaling pathway of EGCG on PC3 human prostate cancer ...
objective(s) recent studies revealed the neuroprotective effects of epigallocatechin gallate (egcg) on a variety of neural injury .the purpose of this study was to determine the effects of egcg on the tissue lipid peroxidation after spinal cord injury (sci). materials and methods rats were randomly divided into four groups of 7 rats each as follows: sham-operated group, trauma group, and egcg-t...

(-)-Epigallocatechin gallate (EGCG) and (-)-epigallocatechin (EGC) are the major polyphenolic constituents in green tea. In this study, we characterized the enzymology of cytosolic catechol-O-methyltransferase (COMT)-catalyzed methylation of EGCG and EGC in humans, mice, and rats. At 1 microM, EGCG was readily methylated by liver cytosolic COMT to 4"-O-methyl-EGCG and then to 4',4"-di-O-methyl-...
Due to the anti-diabetic and antioxidant activity of green tea epigallocatechin-gallate (EGCG), this research study was conducted to evaluate, for the first time, the efficacy of chronic treatment of EGCG on alleviation of hyperalgesia in streptozotocin-diabetic (STZ-diabetic) rats. Male Wistar rats were divided into control, diabetic, EGCG-treated-control and diabetic and sodium salicylate (SS...
(-)-Epigallocatechin-3-gallate (EGCG), the major bioactive constituent in green tea, has been reported to effectively inhibit the formation and development of tumors. To maximize the effectiveness of EGCG, we attached it to nanogold particles (EGCG-pNG) in various ratios to examine in vitro cytotoxicity and in vivo anti-cancer activity. EGCG-pNG showed improved anti-cancer efficacy in B16F10 mu...
This study evaluated epigallocatechin-3-gallate (EGCG) and epigallocatechin-3-O-(3-O-methyl)-gallate (EGCG-3Me) modified etch-and-rinse adhesives (Single Bond 2, SB 2) for their antibacterial effect and bonding stability to dentin. EGCG-3Me was isolated and purified with column chromatography and preparative high performance liquid chromatography. EGCG and EGCG-3Me were incorporated separately ...
Epigallocatechin gallate (EGCG), the main polyphenolic substance in tea, exhibits well-known biological benefits. In order to improve fat solubility and bioavailability, a novel path for lipase enzymatic transesterification synthesis of acylated EGCG derivatives an ionic liquid solvent was established. The optimal reaction parameters were determined maximum conversion achieved at 98.65%. [Bmim]...
