MedKoo CAT#: 201240

CAS#: 496775-61-2 (free base)

Description: Eltrombopag is a small-molecule, nonpeptide thrombopoietin receptor agonist with megakaryopoiesis-stimulating activity. Eltrombopag binds to and stimulates the transmembrane domain of the platelet thrombopoietin receptor (TPO-R or CD110), a member of the hematopoietin receptor superfamily. Activation of TPO-R leads to the proliferation and differentiation of cells in the megakaryocytic lineage and an increase in platelet production. Eltrombopag was approved by FDA in November 20, 2008.
