Definitions

  • the present application relates to the field of medical chemistry, and more particularly to aminopyrazolopyrimidine compounds, processes for their preparation, pharmaceutical compositions containing the compounds, and their use in the treatment of Trk kinase mediated diseases.
  • NTRK/TRK Tropomyosin receptor kinase
  • Trk family consists mainly of three members, NTRK1/TrkA, NTRK2/TrkB and NTRK3/TrkC.
  • the intact Trk kinase includes three parts: the extracellular region, the transmembrane region, and the intracellular region.
  • the extracellular domain of the Trk kinase when bound to the corresponding ligand, is capable of causing a change in the conformation of the kinase to form a dimer.
  • Trk kinase undergoes autophosphorylation to activate its own kinase activity, which further activates downstream signal transduction pathways (such as MAPK, AKT, PKC, etc.) to produce corresponding biological functions; NGF (nerve growth factor) In combination with TrkA, BDNF (derived neurotrophic factor) binds to TrkB, and NT3 (neurotrophin 3) binds to TrkC.
  • Trk kinase plays an important physiological role in the development of nerves, including the growth and function maintenance of neuronal axons, the development of memory, and the protection of neurons from injury.
  • Trk signaling pathway is also strongly correlated with the occurrence and development of tumors.
  • Activated Trk signaling proteins are found in neuroblastoma, prostate cancer and breast cancer.
  • the discovery of various Trk fusion proteins in recent years has further demonstrated its biological function of promoting tumorigenesis. The earliest TPM3-TrkA fusion protein was found in colon cancer cells with an incidence of approximately 1.5% in clinical patients tested.
  • Trk fusion proteins such as CD74-NTRK1, MPRIP-NTRK1, QKI-NTRK2, ETV6, were found in different types of clinical tumor patients such as lung cancer, head and neck cancer, breast cancer, thyroid cancer, and glioma. -NTRK3, BTB1-NTRK3, etc. These different NTRK fusion proteins are themselves in a highly activated kinase activity state without ligand binding, thereby enabling continuous phosphorylation of downstream signaling pathways, inducing cell proliferation, and promoting tumorigenesis and progression. Therefore, in recent years, Trk fusion proteins have become an effective anti-cancer target and research hotspot.
  • WO2010048314, WO2012116217, WO2010033941 and the like disclose Trk kinase inhibitors having different mother nucleus.

Etna, Annals of Oncology 2016, 27(5), 920-926), and the search for new Trk kinase inhibitors are expected to address the issue of tumor resistance caused by NTRK mutations.

本申请要求向中华人民共和国国家知识产权局于2016年10月28日提交的第201610970314.3号和于2017年01月21日第201710044000.5号中国发明专利申请的权益,在此将它们的全部内容以援引的方式整体并入本文中。
技术领域
本申请涉及医药化学领域,更具体地,涉及氨基吡唑并嘧啶化合物、其制备方法、含有该化合物的药物组合物、以及其在治疗Trk激酶介导的疾病中的用途。
背景技术
NTRK/TRK(Tropomyosin receptor kinase)为神经营养因子酪氨酸激酶受体,隶属于受体酪氨酸激酶家族。Trk家族主要包括3个成员,NTRK1/TrkA,NTRK2/TrkB和NTRK3/TrkC。完整的Trk激酶包括胞外区、跨膜区和胞内区三个部分。Trk激酶的胞外区与相应的配体结合之后,能够引起激酶构型变化,形成二聚体。Trk激酶的胞内区发生自体磷酸化从而激活自身的激酶活性,进而进一步激活下游的信号转导通路(如MAPK,AKT,PKC等),产生相应的生物学功能;其中NGF(神经生长因子)结合TrkA,BDNF(衍生的神经营养因子)结合TrkB,以及NT3(神经营养因子3)结合TrkC。
Trk激酶在神经的发育过程中发挥重要的生理功能,包括神经元轴突的生长与功能维持、记忆的发生发展以及保护神经元免受伤害等等。同时,大量的研究表明Trk信号转导通路的活化与肿瘤的发生发展也有很强的相关性,在神经细胞瘤、前列腺癌、乳腺癌等中都发现了活化的Trk信号蛋白。近几年来多种Trk融合蛋白的发现,更显示了其促进肿瘤发生的生物学功能。最早的TPM3-TrkA融合蛋白是在结肠癌细胞中发现的,在检测的临床病人中约有1.5%的发生率。后来在不同类型的临床肿瘤病人样本如肺癌,头颈癌、乳腺癌、甲状腺癌、神经胶质瘤等中发现了不同类型的Trk融合蛋白,如CD74-NTRK1,MPRIP-NTRK1,QKI-NTRK2,ETV6-NTRK3,BTB1-NTRK3等。这些不同的NTRK融合蛋白在不需要配体结合的情况下,自身处于高度活化的激酶活性状态,因而能够持续性的磷酸化下游的信号途径,诱导细胞增殖,促进肿瘤的发生、发展。因此,近几年来,Trk融合蛋白已经成为一个有效的抗癌靶点和研究热点,例如WO2010048314、WO2012116217、WO2010033941等均公开了具有不同母核的Trk激酶抑制剂。此外,持续给药后出现的靶标突变是肿瘤产生耐药性 的重要原因,近期临床上已经出现了NTRK突变的病例,如NTRK1 G595R和G667C的突变(Russo M等.Cancer Discovery,2016,6(1),36-44)、NTRK3 G623R的突变(Drilon A.等Annals of Oncology 2016,27(5),920-926),而寻找新的Trk激酶抑制剂有望解决NTRK突变引起的肿瘤耐药性问题。

药代动力学实验
雄性SD大鼠来源于北京维通利华实验动物技术有限公司,将大鼠分组,每组3只,分别单次灌胃给予待测样品的混悬液(5mg/kg)。动物在实验前禁食过夜,禁食时间从给药前10小时至给药后4小时。给药后0.25、0.5、1、2、4、6、8、和24小时采血。使用小动物麻醉机经异氟烷麻醉后通过眼底静脉丛取0.3mL全血,放于肝素抗凝管中。样品于4℃以4000rpm离心5min,血浆转移至离心管中,并放于-80℃保存直到分析。血浆中样品使用蛋白质沉淀法萃取,萃取液通过LC/MS/MS分析。
