megakaryocytes

Avatrombopag (YM477) 是一种新型口服血小板生成素 (TPO) 受体激动剂，可激活 TPO 受体并增加巨核细胞增殖 分化和血小板生成。

Megakaryocytes platelets inducing agent being useful in treating diseases involving thrombopenia. Megakaryocytes platelets inducing agent is an inducing agent for megakaryocytes and or platelets from pluripotent stem cells.

Avatrombopag hydrochloride (AKR-501) is an orally active, nonpeptide agonist of the thrombopoietin (TPO) receptor with an EC 50 of 3.3 nM. It effectively mimics the biological activities of TPO, stimulating platelet production by activating the intracellular signaling system and facilitating the generation of platelets and megakaryocytes from hemopoietic precursor cells. Additionally, Avatrombopag hydrochloride serves as a substrate for cytochrome P450 (CYP) 2C9 and CYP3A.

Pipobroman (Vercyte) 是一种烷基化剂，是哌嗪的溴化衍生物。它通过抑制 DNA 和 RNA 聚合酶或减少嘧啶核苷酸掺入 DNA 发挥其作用。它在真性红细胞增多症和原发性血小板增多症中具有良好的临床活性，可用于癌症研究。

Totrombopag, also known LGD-4665, GSK2285921 and SB559448, is an oral thromobopoietin receptor agonist, is being developed as a new generation small molecule thrombopoietin (TPO) mimetic. It is a highly selective and potent agonist of the TPO receptor and therefore induces differentiation and proliferation of megakaryocytes. The pharmacologic characteristics indicate potential therapeutic use in thrombocytopenic patients with a variety of clinical etiologies.

Avatrombopag, also known as AKR-501, YM477, AS 1670542 or E5501, is a novel orally-active thrombopoietin (TPO) receptor agonist. AKR-501 specifically targeted the TPO receptor and stimulated megakaryocytopoiesis throughout the development and maturation of megakaryocytes just as rhTPO did. AKR-501 may be useful in the treatment of patients with thrombocytopenia. Avatrombopag was first approved in 2018.

Krds peptide is a synthetic tetrapeptide derived from lactotransferrin (residues 39 to 42) that suppresses binding of monoclonal antibody against glycoprotein IIb-IIIa on ADP-Stimulated platelets and megakaryocytes.
