Disclosed is a class of compounds which inhibit the enzymatic conversion of fructose-lysine into fructose-lysine-3-phosphate in an ATP dependent reaction in a newly discovered metabolic pathway. According to the normal functioning on this pathway, fructose-lysine-3-phosphate (FL3P) is 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 contributing cause of diabetic complications. 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.

L'invention concerne une famille de composés qui inhibent la conversion enzymatique de la fructose-lysine en fructose-lysine-3-phosphate, lors d'une réaction nécessitant de l'ATP, et ce dans une voie métabolique récemment découverte. Selon le fonctionnement normal de cette voie, la fructose-lysine-3-phosphate (FLP3) se dégrade en vue de donner un phosphate inorganique ne contenant pas de lysine et du 3-déoxyglucosone (3DG), ce dernier étant un agent réactif modificateur de protéine. Le 3DG peut être détoxifié par réduction en 3-déoxyfructose (3DF), ou il peut réagir avec des protéines endogènes en vue de former des protéines modifiées de produit terminal en phase de glycation avancée (protéines AGE), qui sont supposées contribuer aux complications diabétiques. L'invention concerne également des procédés thérapeutiques d'utilisation de ces inhibiteurs en vue de réduire la formation de protéines AGE et, par conséquent d'alléger, de réduire, et de retarder les complications diabétiques, ainsi que des procédés permettant d'évaluer le risque du diabétique de développer des complications, et permettant de déterminer l'efficacité du traitement inhibiteur objet de l'invention, en calculant le rapport 3DG/3DF dans un échantillon biologique à la suite d'une ingestion d'un produit alimentaire contenant de la fructose-lysine.
