权利人:SELCUK UNIV; ANADOLU UNIV
摘要:The present invention relates to a method for the synthesis of isorhamnetin metabolite from the quercetin molecule and the isorhamnetin metabolite synthesized by this method. In this method, isorhamnetin is synthesised from quercetin molecule by microbial transformation of Aspergillus flavus. The method of the present invention provides the synthesis of isorhamnetin with 18.20% yield in a short time and at low cost.

标题 :Methods and compositions for enhancing collagen and proteoglycan 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; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.

权利人:NITROMED INC
摘要:The invention describes novel nitrosated and/or nitrosylated pyruvate compounds and pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitrosated and/or nitrosylated pyruvate compound, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel compositions comprising at least one pyruvate compound and at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one pyruvate compound, that is optionally nitrosated and/or nitrosylated, and, optionally, at least one nitric oxide donor and/or at least one therapeutic agent. The invention also provides methods for treating diseases resulting from oxidative stress, diabetes, reperfusion injury following ischemia, preservation of tissues, organs, organ parts and/or limbs.

权利人:NESTEC SA
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.

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 during periods of negative energy balance, or energy deficit. The methods include administering to an individual suffering from energy deficit a composition comprising protein in an amount from about 15 g to about 30 g during a time period selected from the group consisting of during exercise, post-exercise, and combinations thereof. The methods also include administering to an individual suffering from energy deficit a composition comprising protein during a time period selected from the group consisting of during exercise, post-exercise, and combinations thereof, wherein the protein is administered in a dose that is higher than doses typically recommended for individuals experiencing energy balance.
