Abstract

Hepcidin has emerged as the central regulatory molecule of systemic iron homeostasis. Inhibition of Hepcidin could be a strategy favorable to treating anemia of chronic disease (ACD). We report herein the synthesis and structure-activity relationships (SARs) of a series of benzisoxazole compounds as orally active Hepcidin production inhibitors. The optimization study of multi kinase inhibitor 1 led to a potent and bioavailable Hepcidin production inhibitor 38 (DS79182026), which showed serum Hepcidin lowering effects in a mouse IL-6 induced acute inflammatory model.
