Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungere μL Olio di mais, mescolare e chiarire.

Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nell'aggiunta precedente, sia una soluzione limpida prima di procedere all'aggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno d'acqua calda possono essere utilizzati per facilitare la dissoluzione.

Meccanismo d'azione (Mechanism of Action)

Targets/IC₅₀/Ki	thrombopoietin receptor (TpoR)
In vitro	Eltrombopag demonstrates a half maximal effective concentration (EC50) of 0.27 μM in murine BAF3 cells transfected with the luciferase reporter gene under direction of the STAT-activated IRF-1 promoter and human TpoR (BAF3/IRF-1/hTpoR). This compound activates the receptor by association with metal ions (i.e., Zn2+) and specific amino acids within the transmembrane and juxtamembrane domains of the TpoR. It (30 μM) results in activation of STAT5 in N2C-Tpo cells, as detected with an antiphospho-STAT5 antibody on Western blots. This chemical stimulates proliferation after a 2-day incubation with an EC50 of 0.03 μM in a BrdU assay conducted in BAF3/hTpoR cells. It also induces differentiation of hematopoietic stem cells into committed megakaryocyte progenitor cells. This compound increases the differentiation of bone marrow CD34+ cells into CD41+ megakaryocytes in a dose-dependent manner with an EC50 of 0.1 μM. It inhibits N2C-Tpo cell and HEL92.1.7 cell proliferating with IC50 of 20.7 μg/mL and 2.3 μg/mL. This chemical (20 μg/mL) leads to a decreased cell division rate, a block in G(1) phase of cell cycle, and increased differentiation in human and murine leukemia cells. It (5 μg/mL) shows clear signs of differentiation, significant changes in the organization of the nuclear contents, and an increase in the cytoplasm/nucleus ratio in HL60 cells. This compound (5 μg/mL) causes an increase in CD11b, which is consistent with a premacrophage state in U937 cells, and also causes an increase in CD11b in URE cells. It leads to a reduction in free intracellular iron in leukemic cells in a dose-dependent manner in HL60 cells.
In vivo	Eltrombopag (10 mg/kg per day) increases platelet counts over twofold approximately 1 week after the last dose for one chimpanzee and approximately 1.5-fold for the other two chimpanzees. This compound (1 mg/mL) prolongs survival in mouse models of leukemia.
