Eltrombopag is an orally bioavailable nonpeptide agonist of the thrombopoietin receptor (EC50 = 0.27 µM in a reporter assay) and an iron chelator. It increases STAT5 phosphorylation in N2C-Tpo cells when used at a concentration of 30 µM and p42/44 MAPK phosphorylation when used at 10 µM. Eltrombopag binds to the...

AZD 1152 is an orally bioavailable prodrug of AZD 1152-HQPA, a selective inhibitor of Aurora kinase B (IC50 = 0.36 nM). AZD 1152 is converted to AZD 1152-HQPA in plasma. Inhibition of Aurora B results in disruption of spindle checkpoint functions and chromosome alignment, resulting in inhibition of cytokinesis...
