Patent

CA 2210257

The present invention relates to compositions and methods for inhibiting nonenzymatic cross-linking (protein aging). Accordingly, a composition is disclosed which comprises a dioone bis[hydrazone] capable of inhibiting the formation of advanced glycosylation endproducts of target proteins by reacting with the carbonyl moiety of the early glycosylation product of such target proteins formed by their initial glycosylation. The method comprises contacting the target protein with the composition. Both industrial and therapeutic applications for the invention are envisioned, as food spoilage and animal protein aging can be treated.

La présente invention a pour objet des compositions et des procédés pour inhiber la réticulation nonenzymatique (vieillissement des protéines). Par conséquent, une composition est décrite qui comprend un dione bis(hydrazone) permettant d'inhiber la formation de produits finaux de la glycosylation avancée de protéines cibles en réagissant avec la fraction carbonyle du produit de la glycosylation précoce de ces protéines cibles formés par leur glycosylation initiale. Le procédé consiste à placer la protéine cible en contact avec la composition. Les applications industrielles et thérapeutiques sont prises en compte; les gaspillages alimentaires et le vieillissement des protéines animales en sont des exemples.
