Background

VIT-2763, an oral ferroportin inhibitor, inhibits hepcidin binding to ferroportin and blocks iron efflux. VIT-2763 has the potential in the treatment of β-thalassemia[1].

VIT-2763 dose dependently reduces the fluorescence polarization signal, indicating that VIT-2763 displaces TMR-hepcidin from ferroportin (IC50 of 24 ± 13 nM)[1].VIT-2763 induces BLA reporter gene activity with an average EC50 of 140 ± 50 nM, as a consequence of increasing intracellular iron concentrations caused by blocked iron export in HEK293 cells[1].VIT-2763 (100 nM) triggers ubiquitination and subsequent internalization and degradation of ferroportin[1]. Cell Viability Assay[1]. Cell Line: J774 cells.

VIT-2763 (30, 100 mg/kg, orally twice daily for 36 days) decreases serum iron and prevented liver iron loading in Hbbth3/+ mice[1].VIT-2763 did not change the total liver iron[1].VIT-2763 (30, 100 mg/kg, orally twice daily for 36 days) significantly corrects anemia and improved RBC parameters in Hbbth3/+ mice. VIT-2763 decreases the percentage of ROS-positive RBCs in Hbbth3/+ mice from 67% to 30%[1].VIT-2763 decreases apoptosis and extends the life span of RBCs in Hbbth3/+ mice[1]. Animal Model: Hbbth3/+ mice[1].
