Dietary supplementation with ipriflavone decreases hepatic iron stores in wild type mice.

ABSTRACT: Hepcidin, a peptide produced in the liver, decreases intestinal iron absorption and macrophage iron release by causing degradation of the iron exporter, ferroportin. Because its levels are inappropriately low in patients with iron overload syndromes, hepcidin is a potential drug target. We previously conducted a chemical screen that revealed ipriflavone, an orally available small molecule, as a potent inducer of hepcidin expression. To evaluate ipriflavone's effect on iron homeostasis, we placed groups of 5-week old wild type or thalassemia intermedia (Hbb(Th3+/-)) mice on a soy-free, iron-sufficient diet, AIN-93G containing 220mg iron and 0-750mgipriflavone/kg of food for 50days. Ipriflavone 500mg/kg significantly reduced liver iron stores and intestinal ferroportin expression in WT mice,
