Abstract:

Non-enzymatic accumulation of advanced glycation end-products (AGE) is to some extent a physiologic consequence of tissue aging. On the other hand, circulating AGE and tissue deposits mark the course of diabetes mellitus as well as a variety of other vascular or degenerative diseases. AGE generation is paralleled by oxidative damage and lipid peroxidation within target tissue, with features of inflammation through the involvement of monocytes/macrophages expressing receptors for glycated macromolecules. Over the past 15 years, a wealth of data concerning the pharmacology of AGE have been gathered through animal and human investigations, targeting their likely contribution to the progression of diabetic and non-diabetic vascular damage. Several agents have been shown to interfere with the formation of AGE or AGE precursors, bind to tissue receptors, or promote breakdown of deposits. The first and most studied inhibitor, aminoguanidine, has shown extensive beneficial effects in experimental models of diabetic vascular damage, recently entering phase I–III clinical investigation. Newer anti-AGE agents include pyridoxamine and the so-called ‘amadorins’, cross-link breakers, AGE binders and receptor antagonists.
