摘要:
The present invention is based on the discovery of a metabolic pathway in which a specific kinase converts fructose-lysine into fructose-lysine-3-phosphate in an ATP dependent reaction. Fructose-lysine-3-phosphate (FL3P) is then broken down to form free lysine, inorganic phosphate and 3-deoxyglucosone (3DG), the latter being a reactive protein modifying agent. 3DG can be detoxified by reduction to 3-deoxyfructose (3DF), or it can react with endogenous proteins to form advanced glycation end-product modified proteins (AGE-proteins), which are believed to be a cause of diabetic complications. Disclosed is a class of compounds which inhibit the action of FL3P kinase in the above-mentioned pathway. Also disclosed are therapeutic methods of using such inhibitors to reduce formation of AGE-proteins and thereby lessen, reduce and delay diabetic complications, as well as methods for assessing a diabetic's risk of developing complications and for determining the efficacy of the disclosed inhibitor therapy by measuring the ratio of 3DG to 3DF in a biological sample following an oral dose of a fructose-lysine-containing food product.
摘要:
The invention relates to compounds and methods for inhibiting production and function of 3-deoxyglucosone and other alpha-dicarbonyl sugars in skin, by way of fructosamine-3-kinase inhibition, thereby treating or prevention various diseases, disorders or conditions. Additionally, the invention relates to treatment of various diseases, disorders or conditions associated with or mediated by oxidative stress since 3DG induces ROS and AGEs, which are associated with the inflammatory response caused by oxidative stress.
摘要:
Compositions are disclosed which have as a component thereof an inhibitor of the enzymatic production of 3-deoxyglucosone (3DG) from fructoselysine and/or an inactivator of 3DG, and which are useful for the treatment or prophylaxis of a condition or disease state that is alleviated by inhibiting such 3DG production. Methods of using such compositions, e.g., for improving the appearance, texture and/or elasticity of aging skin, are also disclosed.
