Inhibitors of the Maillard reaction and AGE breakers as therapeutics for multiple diseases.

The Maillard reaction is a complex series of reactions that involve reducing-sugars and proteins, giving a multitude of end-products that are known as advanced glycation end-products (AGEs). AGEs can contribute to the pathogenesis of diabetes and neurological diseases such as Alzheimer's disease. AGEs also play a major role in vascular stiffening, atherosclerosis, osteoarthritis, inflammatory arthritis and cataracts. Thus, AGE inhibitors and AGE breakers offer a potential strategy as therapeutics for diverse diseases. Various AGE inhibitors have been developed in recent years, and their underlying mechanism is based on the attenuation of glycoxidation and/or oxidative stress by the sequestration of metal ions, reactive 1,2-dicarbonyl compounds, and reactive oxygen and reactive nitrogen species.
