Synthesis and SAR studies of 3,6-disubstituted indazole derivatives as potent hepcidin production inhibitors

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 indazole compounds as hepcidin production inhibitors. The optimization study of compound 1 led to a potent hepcidin production inhibitor 45, which showed serum hepcidin lowering effects in a mouse IL-6 induced acute inflammatory model.

Discovery of DS79182026: A potent orally active hepcidin production inhibitor

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.

Discovery of DS28120313 as a potent orally active hepcidin production inhibitor: Design and optimization of novel 4,6-disubstituted indazole derivatives

Hepcidin has emerged as the central regulatory molecule in systemic iron homeostasis, and its inhibition could be a favorable strategy for treating anemia of chronic disease (ACD). Here, we report the design, synthesis and structure-activity relationships (SAR) of a series of 4,6-disubstituted indazole compounds as hepcidin production inhibitors. The optimization study of multi-kinase inhibitor 1 led to the design of a potent and bioavailable hepcidin production inhibitor, 32 (DS28120313), which showed serum hepcidin-lowering effects in an interleukin-6-induced acute inflammatory mouse model.
