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.

标 题 :Methods and compositions for enhancing collagen, proteoglycan, and glutathione synthesis in the skin
发明人：NIMNI MARCEL; HAN BO
权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids or hydrolyzed whey protein; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid or a lipoic acid analogue or derivative. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.
