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.
