Zilurgisertib fumarate (INB-000928 fumarate) is a potent and selective inhibitor of Activin Receptor-Like Kinase 2 (ALK2/ACVR1). It significantly inhibits ALK2 kinase activity (IC50 = 15 nM) and downregulates BMP-6-induced SMAD1/5 phosphorylation (IC50 = 63 nM). By blocking ALK2-mediated signaling, Zilurgisertib suppresses the production of hepcidin in hepatocytes (IC50 = 20 nM), thereby modulating iron metabolism. In preclinical studies, Zilurgisertib demonstrates the potential to improve anemia in cancer-induced models by effectively increasing hemoglobin levels.

| Targets&IC50 | ALK2:15 nM, Smad1/5:63 nM, Hepcidin production:20 nM |
| In vitro | Zilurgisertib fumarate inhibits ALK2 kinase activity (IC50 = 15 nM) and suppresses BMP-6-induced SMAD1/5 phosphorylation (IC50 = 63 nM). In Huh-7 cells, it potently reduces BMP-6-stimulated hepcidin production with an IC50 of 20 nM [2]. |
| In vivo | Systemic administration of Zilurgisertib fumarate improves anemia in mouse models of cancer-induced anemia. It effectively increases hemoglobin (Hb) levels and red blood cell (RBC) counts, demonstrating its potential to restore iron homeostasis in chronic disease environments [2]. |
