Definitions

  • the present invention relates to a 2-acylaminothiazole derivative, and more particularly to a 2-acylaminothiazole derivative which can be used as a thrombopoietin receptor agonist.
  • the invention further relates to a process for the preparation of the 2-acylaminothiazole derivatives, to pharmaceutical compositions and to their use in the treatment of diseases mediated by thrombopoietin.
  • the thrombopoietin (TPO) receptor is a member of the thrombopoietin growth factor receptor family. This receptor family is characterized by a common extracellular structure, including the N-terminal portion of a similar C residue and the WSXWS signature near the transmembrane region. Expression of the TPO receptor is restricted to spleen, bone marrow, fetal liver and human megakaryocytes, platelets, CD34+ cells. These evidences suggest that TPO receptors play a role in hematopoiesis.
  • Platelets are very important in physiological hemostasis and pathological thrombosis. It is constantly produced by megakaryocytes in the body. Megakaryocytes are cells that produce polyploid cells by nucleus mitosis in the nucleus, without nuclear division of cell division. When the number of platelets is reduced, the rate of mitosis in the nucleus increases, forming more polyploid megakaryocytes, which may increase by a factor of three. Conversely, when the platelet count is increased, the rate of mitosis in the nucleus is reduced, the formation of polyploid megakaryocytes is reduced, and the number of megakaryocytes may be reduced by 50%.
  • TPO has been shown to play a major humoral regulation in the case of thrombocytopenia. Some studies have shown that TPO can increase platelet count and increase platelet volume.
  • TPO affects megakaryocytes in the following ways: (1) it increases the size and number of megakaryocytes; (2) it increases the DNA content of polyploid megakaryocyte morphology; (3) Increase nuclear mitosis in megakaryocytes; (4) it increases megakaryocyte maturation; (5) it produces a certain percentage of acetylcholinesterase-positive precursor cells in the bone marrow.
  • TPO is also used in the diagnosis and treatment of various blood diseases. Potential applications, such as diseases caused primarily by platelet defects. To this end, researchers have developed a series of compounds targeting thrombopoietin receptors, and it is expected to prevent or treat diseases or conditions caused by platelet defects or reduction by promoting platelet production.
  • WO 2005/014561, WO 2009/017098 and WO 2007/004038 disclose the use of a 2-aminothiazole derivative for the treatment of thrombocytopenia.
  • the above compounds all exhibit varying degrees of pharmacological activity to prevent thrombocytopenia, their activity has not reached a satisfactory level.
  • some of the drugs that have been approved for marketing have also shown a certain degree of side effects, which hinder the wide clinical application of these drugs.
  • TPO sexual immune thrombocytopenia
  • eltrombopag and lusutrombopag target TPD receptors in targeted severe aplastic anemia and chronic primary It plays a role in the treatment of sexual immune thrombocytopenia (ITP) (Ali et al; Blood Coagulation & Fibrinolysis, 27(1), 4-52, (2016)).
  • ITP sexual immune thrombocytopenia
  • Eltrombopab is well tolerated by humans, it has severe hepatotoxic side effects, which greatly limits its clinical application. Therefore, finding a more effective TPO receptor agonist with fewer side effects has urgent clinical needs and important significance.
  • the inventors of the present invention have intensively studied to obtain a novel 2-acylaminothiazole derivative in which the 5-position carbon of the novel 2-acylaminothiazole derivative is substituted with a cyclic nitrogen-containing group. As a result, it was found that the compound of the present invention has very excellent TPO receptor agonistic activity while exhibiting excellent metabolic stability of liver microsomal P450 oxidase.

Description

2-酰氨基噻唑类衍生物及其制备方法与用途 技术领域
本发明涉及2-酰氨基噻唑类衍生物,更具体而言,涉及可用作血小板生成素受体激动剂的2-酰氨基噻唑类衍生物。本发明还涉及该2-酰氨基噻唑类衍生物的制备方法、药物组合物以及其在治疗血小板生成素所介导的疾病中的用途。
背景技术
血小板生成素(Thromboietin,TPO)受体是血小板生成素生长因子受体家族的成员之一。这个受体家族的特征是有一个共同的胞外结构,包括相似的C残基的N-末端部分和接近跨膜区的WSXWS特征结构。TPO受体的表达限制在小鼠的脾脏、骨髓、胎肝和人类的巨核细胞、血小板、CD34+细胞中。这些证据表明,TPO受体在造血过程中发挥作用。
血小板在生理性止血和病理性血栓形成方面非常重要。它是由生物体内的巨核细胞不断产生的。巨核细胞是由骨髓细胞经过核内有丝分裂,不进行细胞分裂的细胞核复制,而产生多倍体的细胞。当血小板数量的降低时,核内有丝分裂速率会增加,形成更多多倍体巨核细胞,使其数量可能会增加到3倍。相反地,当血小板计数升高时,核内有丝分裂的速率会降低,多倍体巨核细胞的形成会减少,巨核细胞的数量可能会减少50%。尽管循环血小板是如何调节核内有丝分裂速率和骨髓内巨核细胞数量的确切机理尚不清楚,但血小板生成素目前被认为是参与介导这一反馈机制的造血因子。TPO被证实在血小板减少的情况下起主要的体液调节作用。一些研究显示TPO能增加血小板计数并使血小板体积增大。更准确的说,TPO在下几个方面影响巨核细胞:(1)它能使巨核细胞的大小和数量增加;(2)它能使在多倍体的巨核细胞形态的DNA含量增加;(3)增加巨核细胞的核内有丝分裂;(4)它能增加巨核细胞成熟;(5)在骨髓中它产生一定百分比的乙酰胆碱酯酶阳性的前体细胞。
由于血小板是血液凝固所必需的,当它们的数量非常低时,患者可能存在灾难性的出血风险。TPO在各种血液疾病诊断和治疗中也有 潜在应用,比如对主要是由于血小板缺陷引起的疾病。为此,科研人员开发合成了一系列以血小板生成素受体为靶点的化合物,期望通过促进血小板的生成来预防或治疗因血小板缺陷或减少所导致的疾病或病症。
例如,WO 2005/014561、WO 2009/017098和WO 2007/004038公开了类似2-氨基噻唑衍生物治疗血小板减少症的用途。虽然上述化合物均不同程度地表现出了一定的阻止血小板减少的药理活性,但是它们的活性还不能到达足以令人满意的程度。而且,目前已经批准上市的一些药物还表现出了一定程度的副作用,这些副作用阻碍这些药物在临床上的广泛应用。例如,作为最近批准的口服用的TPO受体小分子激动剂药物,艾曲波帕(eltrombopag)和芦曲泊帕(lusutrombopag)通过TPO受体在靶向性重型再生障碍性贫血和慢性原发性免疫性血小板减少症(ITP)的治疗中发挥作用(Ali等;Blood Coagulation&Fibrinolysis,27(1),4-52,(2016))。然而,尽管艾曲波帕对人有很好的耐受性,但它有严重的肝毒性副作用,这大大限制了其在临床上的应用。因此,寻找一个更有效的且副作用更小的TPO受体激动剂在临床上有着迫切的需求和重要的意义。

试验例
试验例1
血小板生成素(Thrombopotein,TPO)是一种与产生血小板有关的糖蛋白,在调节巨核细胞生成和骨髓巨核细胞生成血小板的过程中起关键作用。体外合成TPO模拟化合物,化合物可与细胞上的TPO受体(TPOR)作用,刺激细胞的增殖和分化。通过MTS方法检测OD490值,细胞数目越多,OD值越大,从而检测化合物对细胞增殖分化的响应。信号增加达到最高水平的激动剂浓度为Emax,信号增加到50%Emax的化合物浓度为EC50。通过EC50对化合物的活性进行判断,EC50越小,化合物活性越高。
将稳定表达人TPOR的小鼠原B细胞BAF3培养于含有10%FBS的1640培养基中。检测当天,将细胞计数后,接种于多孔板中。将不同浓度待测化合物加入孔板中,使其终浓度分别为10000nM,3000nM,300nM,30nM,3nM,0.3nM,0.03nM,化合物与细胞在培养箱中共孵育24h后。用多功能全自动酶标仪检测OD 490,用GraphPad Prism5软件拟合EC50
