(E/Z)-Eltrombopag-C 4 is a mixture complex of E-Eltrombopag and Z-Eltrombopag, with C labeled. Z-Eltrombopag is an orally active thrombopoietin receptor nonpeptide agonist. Eltrombopag owns thrombopoietic activity, and has been used to research low blood platelet counts with chronic immune thrombocytopenia. Eltrombopag can be used for the research of cardiovascular. Eltrombopag also has highly inhibitory effects against multidrug resistant Staphylococcus aureus. Eltrombopag can induce apoptosis in hepatocellular carcinomab (HCC) as well[1][2][3][4][5].
