Deferoxamine is a bacterial siderophore produced by the actinobacteria Streptomyces pilosus. It has medical applications as a chelating agent used to remove excess iron from the body. The mesylate salt of DFO-B is commercially available. Deferoxamine acts by binding free iron in the bloodstream and enhancing its elimination in the urine. By removing excess iron, the agent reduces the damage done to various organs and tissues, such as the liver. A recent study also shows that it speeds healing of nerve damage (and minimizes the extent of recent nerve trauma). Deferoxamine may modulate expression and release of inflammatory mediators by specific cell types.
