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

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

Animal Model:NOD/SCID mice (transplanted with human FL CD34+cells)[1]
-
Dosage:0.3, 1, and 3 mg/kg
-
Administration:P.o.; daily for 14 days
-
Result:Dose-dependently increased the number of human platelets, resulting in approximately a 2.7‐fold increase at 1 mg/kg/d and a 3.0-fold increase at 3 mg/kg/d on day 14 after the start of administration.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.83 mg/mL (1.21 mM); Clear solution
This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
