Definitions

  • the present invention relates to the technical field of chemical medicine, and in particular to a HPK1 kinase inhibitor and a preparation method and application thereof.
  • Hematopoietic progenitor kinase 1 is a hematopoietic system-specific serine/threonine protein kinase that belongs to the MAP4K family of mammalian STE20-related protein kinases. HPK1 is mainly expressed in hematopoietic tissues and cells. A large number of research results have shown that HPK1 is involved in a variety of cellular events, including mitogen-activated protein kinase signaling, nuclear factor- ⁇ B signaling, cytokine signaling, cell proliferation and apoptosis, T cell receptor/B cell receptor signaling, and T/B/dendritic cell-mediated immune responses.
  • HPK1 is a potential target for tumor immunotherapy.
  • Sawasdikosol et al. reported that destroying the HPK1 gene of T cells and DC cells helps inhibit the growth of lung cancer cells.
  • HPK1 can be used as a new target for anti-tumor immunotherapy (Sawasdikosol S, Zha R, Yang B, Burakoff S. HPK1 as a novel target for cancer immunotherapy. Immunol Res. 2012 Dec; 54(1-3): 262-5.).
  • HPK1 kinase is a key negative feedback regulator of TCR signaling, which will destroy the stability of the TCR signaling complex. Inhibition of HPK1 can enhance T cell activity.
  • HPK1 can serve as an attractive drug target for improving immunotherapy response (for example, Si, J., Shi, X., Sun, S., Zou, B., & Liao, X.. (2020).
  • Hematopoietic progenitor kinase 1 (hpk1) mediates t cell dysfunction and is a druggable target for t cell-based immunotherapies. Cancer Cell, 38 (4).).
  • HPK1 kinase plays a key role in disease treatment, especially cancer treatment, and the discovery of small molecule inhibitors of HPK1 kinase is currently an urgent need.
  • the present invention discloses a compound and a preparation method and application thereof, which can regulate (e.g., inhibit) HPK1 kinase activity and can be used to treat a variety of HPK1-related diseases including autoimmune diseases, inflammatory diseases, and tumors.

Description

一种HPK1激酶抑制剂及其制备方法和应用 技术领域
本发明涉及化学医药技术领域,具体涉及一种HPK1激酶抑制剂及其制备方法和应用。
背景技术
造血祖细胞激酶1(hematopoietic progenitor kinase 1,HPK1,又名MAP4K1)是造血系统特异性丝氨酸/苏氨酸蛋白激酶,属于哺乳动物STE20相关蛋白激酶的MAP4K家族。HPK1主要在造血组织和细胞中表达。大量研究结果表明,HPK1参与多种细胞事件,包括促分裂原活化蛋白激酶信号传导、核因子-κB信号传导、细胞因子信号传导、细胞增殖和凋亡、T细胞受体/B细胞受体信号和T/B/树突状细胞介导的免疫反应,在免疫中具有多种作用,并与自身免疫性疾病、癌症和炎症反应的发病机制有关(例如Zhang Q,Ding S,Zhang H.Interactions between hematopoietic progenitor kinase 1and its adaptor proteins(Review).Mol Med Rep.2017 Nov;16(5):6472-6482.中所述)。
临床研究表明,HPK1是一种潜在的肿瘤免疫治疗靶点,例如Sawasdikosol等人报道了破坏T细胞和DC细胞的HPK1基因有助于抑制肺癌细胞的生长,HPK1可作为抗肿瘤免疫治疗的新靶点(Sawasdikosol S,Zha R,Yang B,Burakoff S.HPK1as a novel target for cancer immunotherapy.Immunol Res.2012 Dec;54(1-3):262-5.)。此外,据报道,HPK1激酶是TCR信号的关键负反馈调节因子,会破坏TCR信号复合体的稳定性,抑制HPK1可增强T细胞活性,因此,HPK1可作为改善免疫治疗反应的有吸引力的药物靶标(例如Si,J.,Shi,X.,Sun,S.,Zou,B.,&Liao,X..(2020).Hematopoietic progenitor kinase1(hpk1)mediates t cell dysfunction and is a druggable target for t cell-based immunotherapies.Cancer Cell,38(4).中所述)。
可见,HPK1激酶在疾病治疗特别是癌症治疗中具有关键作用,HPK1激酶小分子抑制剂的发现是目前的迫切需求。
