ABSTRACT:
A new and useful fluorescent chromophore has been isolated and identified which has been observed in proteins exposed to glucose over time, and whose fluorescent properties closely resemble those of the polypeptide after it undergoes advanced glycosylation. The chromophore has been structurally identified and named 2-furoyl-4(5)-(2-furanyl)-1H-imidazole, and is believed to be one of the end products of extended nonenzymatic polypeptide glycosylation, which results in the state known as nonenzymatic browning (NEB). The measurement of this chromophore makes possible both qualitative and quantitative assessment of the degree of aging. Diagnostic and test kits are also disclosed.
