Aminoguanidine bicarbonate is primarily used in research settings to study its potential therapeutic effects. It is known for its ability to inhibit the formation of advanced glycation end-products (AGEs), which are linked to complications in diabetes and aging. This makes it a subject of interest in developing treatments for diabetic complications, such as nephropathy, retinopathy, and neuropathy. Additionally, it has been explored for its antioxidant properties, which may help in reducing oxidative stress-related damage in various diseases. In laboratory studies, it is also utilized as a reagent in organic synthesis, particularly in the preparation of heterocyclic compounds. Its role in modulating nitric oxide production has further sparked interest in cardiovascular and inflammatory research.
