Deferitrin is an iron chelator and a derivative of desferrithiocin that binds iron in a 2:1 (ligand:iron) ratio.1,2 It inhibits the proliferation of L1210 murine leukemia cells (IC50 = 17 µM).3 Deferitrin (150 µmol/kg) induces iron excretion in iron-overloaded C. apella monkeys and beagle dogs with an iron clearing efficiency (ICE) of 14.5 and 9.3%, respectively.2 It reduces fecal and urine iron levels by 607 and 357 µg/kg in C. apella monkeys and beagle dogs, respectively.
