产品详情

Avatrombopag (AKR-501) hydrochloride 是一种口服活性的非肽血小板生成素受体 (TPO receptor) 激动剂 (EC₅₀=3.3 nM)。Avatrombopag hydrochloride 可模拟TPO 的生物活性。Avatrombopag hydrochloride 通过激活细胞内信号传导系统来增加血小板的产生，并促进造血前体细胞产生血小板和巨核细胞。Avatrombopag hydrochloride 是细胞色素 P450 (CYP) 2C9 和 CYP3A 的底物。

生物活性

Avatrombopag (AKR-501) hydrochloride is an orally active, nonpeptide thrombopoietin (TPO) receptor agonist (EC 50 =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.

体外研究(In Vitro)

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.
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.
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.

体内研究(In Vivo)

Avatrombopag hydrochloride (0.3-3 mg/kg; p.o.; daily for 14 days) increases the number of human platelets in NOD/SCID mice transplanted with human FL CD34 cells. has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model:

产品使用指南

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
