摘要:The Green Tea Polyphenol Catechin-3-Gallate (Cg) And Epicatechin-3-Gallate (Ecg) Were Synthesized Enantioselectively Via A Sharpless Hydroxylation Reaction Followed By A Diastereoselective Cyclization. Their Potencies To Inhibit The Proteasome Activity Were Measured. The Unnatural Enantiomers Were Found To Be Equally Potent To The Natural Compounds. (C) 2004 Elsevier Ltd,All Rights Reserved.

标 题 :Flavonoid compounds capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells, relative synthesis and their use
发明人：PORTA AMALIA
摘要:The invention relates to flavonoids compounds of formula (I) and (II) capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells. Such compounds are molecules of plant origin or synthetic. The invention also describes a method to identify, purify and chemically synthesize such flavonoid compounds and test their efficacy through their capacity to stimulate the transcription of stress genes and as a consequence, to interact with biological membranes with alteration of their relative physical state. Such compounds and corresponding pharmaceutically acceptable derivatives and/or salts have applications in the areas of pharmaceuticals, more specifically in cosmetics and dermatology, for all those afections related to an alteration of the expression of stress genes.

摘要:A method for synthesizing a biocompatible, water-soluble oligo/polyflavanoid, includes polymerizing an optionally substituted flavanoid with a polymerization agent in the presence of a biocompatible polymerization solubilizer, thereby producing the biocompatible, soluble oligo/polyflavanoid. Also included is a biocompatible, soluble, oligo/polyflavanoid or a pharmaceutically acceptable salt, solvate, or complex thereof. Also included are methods of treating a subject for cancer, cardiac damage, viral infection, and obesity.

摘要:The present disclosure provides methods for enhancing muscle protein synthesis in an individual in need of same. Specifically, the present disclosure provides methods for enhancing muscle protein synthesis by enhancing myofibrillar muscle protein synthesis. The method includes administering to the individual a mixed macronutrient composition having (i) an amount of whey protein that is not capable of enhancing myofibrillar protein synthesis when ingested by itself and (ii) free leucine. The composition comprises at least about 5.0 g total leucine per dose.
