Alteon is developing new classes of drugs that have shown the potential to reverse or slow down diseases of aging and complications of diabetes. These compounds appear to have an impact on a fundamental pathological process caused by the progressive formation of protein-carbohydrate complexes called Advanced Glycation End-products (A.G.E.s). The formation and crosslinking of A.G.E.s lead to a loss of flexibility and function in body tissues and organs and have been shown to be a causative factor in many age-related diseases and diabetic complications. Alteon has created a library of novel classes of compounds targeting the A.G.E. pathway.
