The present invention relates to compositions and methods for inhibiting nonenzymatic cross-linking (protein aging). Accordingly, a composition is disclosed which comprises ;an agent 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. Suitable agents contain an active nitrogen-containing group, such as a hydrazine group. Particular agents comprise aminoguanidine derivatives. 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.
本发明涉及抑制非酶交联(蛋白质老化)的组合物和方法。因此,本发明公开了一种组合物,该组合物包括:能够通过与目标蛋白质由初始糖基化形成的早期糖基化产物的羰基反应,抑制目标蛋白质的晚期糖基化终产物的形成的制剂。合适的药剂含有活性含氮基团,如肼基团。该方法包括将目标蛋白质与组合物接触。本发明既可用于工业,也可用于治疗,因为食品变质和动物蛋白老化均可得到治疗。
