Abstract
The present invention relates to compositions and methods for inhibiting protein aging. Accordingly, a composition is disclosed which comprises an agent or compound capable of inhibiting the formation of advanced glycosylation end products 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 may contain an active nitrogen-containing group, such as a hydrazine group. Particular agents comprise aminoguanidine, .alpha.-hydrazinohistidine and mixtures thereof. 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 tre This invention was made in part with government support under Grant Number PHS AM 19655 awarded by the National Institutes of Health. The government has certain rights in the invention.
