Avatrombopag
Based on 5 publication(s) in Google Scholar
Avatrombopag (AKR-501) is an orally active, nonpeptide thrombopoietin (TPO) receptor agonist (EC50=3.3 nM). Avatrombopag mimics the biological activities of TPO. Avatrombopag increases platelet production by activating the intracellular signaling system, and promotes production of platelets and megakaryocytes from hemopoietic precursor cells. Avatrombopag is a substrate of cytochrome P450 (CYP) 2C9 and CYP3A.

Avatrombopag (E5501; AKR-501) specifically targets the TPO receptor and stimulated megakaryocytopoiesis throughout the development and maturation of megakaryocytes just as recombinant human TPO (rhTPO) did[1].
Avatrombopag (0-100 nM) supports the proliferation of TPO receptor expressing Ba/F3 cell in a concentration-dependent fashion. Avatrombopag (0-3 μM) induces tyrosine phosphorylation of STAT3 and STAT5, and threonine phosphorylation of ERK in the cells, as did rhTPO[1].
Avatrombopag promotes megakaryocyte colony formation from human CB CD34+ cells in a concentration-dependent fashion. The EC50 is 25 nM for Avatrombopag and the maximum activity of Avatrombopag is similar to that of rhTPO[1].
