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.
本发明涉及用于抑制非酶交联(蛋白质老化)的组合物和方法。因此,本发明揭示了一种组合物,其包括:一种能够通过与目标蛋白质的早期糖基化产物的羰基部分反应来抑制目标蛋白质的先进糖基化终产物形成的药剂。适宜的药剂包含一个活性的含氮基团,如一个肼基团。特定的药剂包括氨基胍衍生物。该方法包括将目标蛋白质与该组合物接触。本发明可预见的工业和治疗应用包括食品变质和动物蛋白质老化的治疗。
