deferoxamine
An iron-chelating agent that binds free iron in a stable complex, preventing it from engaging in chemical reactions. Deferoxamine chelates iron from intra-lysosomal ferritin and siderin forming ferrioxamine, a water-soluble chelate excreted by the kidneys and in the feces via the bile. This agent does not readily bind iron from transferrin, hemoglobin, myoglobin or cytochrome.
