Definitions

  • the present invention relates to the field of small molecule drugs. Specifically, the present invention provides a small molecule compound that can be used to treat diseases related to the PD-1/PD-L1 signaling pathway.
  • the immune system plays a vital role in controlling and curing many diseases, such as various cancers and diseases caused by viruses.
  • cancer cells can often evade or suppress the immune system through some means, thereby reproducing rapidly.
  • One way is to change the activation and inhibitory molecules expressed on immune cells. Blocking suppression of immune checkpoints, like PD-1, proved to be a very effective method of suppressing cancer cells.
  • PD-1 is programmed cell death protein-1, also known as CD279. It is mainly expressed in activated T cells and B cells, and its function is to inhibit cell activation. This is a normal homeostasis mechanism of the immune system. Because excessive T/B cell activation can cause autoimmune diseases, PD- 1 is a protective wall for our human body.
  • PD-1 is a type I transmembrane glycoprotein composed of 268 amino acids. Its structure mainly includes the variable region of the extra-immunoglobulin, the hydrophobic transmembrane region and the intracellular region.
  • the intracellular region contains two phosphorylation sites, which are located in the immunoreceptor tyrosine suppression motif and the immunoreceptor tyrosine switching motif, which also proves that PD-1 can reversely regulate T cell receptor-mediated signal.
  • PD-1 has two ligands, PD-L1 and PD-L2, which are different in expression.
  • PD-L1 is up-regulated and expressed in a variety of tumor cells. It binds to PD-1 on T cells, inhibits T cell proliferation and activation, makes T cells in a state of inactivation, and finally induces immune escape.
  • PD-1/PD-L1 plays a reverse immunomodulatory role.
  • PD-1 binds to PD-L1, it can cause the tyrosine polyphosphorylation of the tyrosine conversion motif domain of the immunoreceptor of T cells, and the phosphorylated tyrosine can bind to the phosphatase protein tyrosinase 2 and protein tyrosinase 1.
  • This can block the activation of extracellular signal-regulated kinases, and also block the activation of phosphoinositide 3-kinase (PI3K) and serine-threonine protein kinase (Akt), thereby inhibiting the proliferation of T lymphocytes and the breakdown of related cytokines.
  • PI3K phosphoinositide 3-kinase
  • Akt serine-threonine protein kinase
  • PD-1/PD-L1 signal inhibits T cell activation and proliferation, it can also secrete the cytokines interleukin 2, interferon gamma and IL-10.
  • PD-1/PD-L1 signals have similar immune functions to B cells.
  • the cytoplasmic region of PD-1 interacts with tyrosinase containing protein tyrosinase 2 binding sites. Cataminase acts to hinder the activation of B cells.
  • Immunotherapy based on PD-1/PD-L1 is a new generation of immunotherapy that has attracted much attention.
  • PD-1/PD-L1 inhibitors have strong anti-tumor activity against a variety of tumors.
  • the PD-1/PD-L1 antibody inhibitors currently on the market include BMS’s Ninolumab, Merck’s Lambrolizumab and Roche’s Atezolizumab.
  • BMS Ninolumab
  • Merck s Lambrolizumab
  • Roche Roche’s Atezolizumab.
  • there are many PD-1/PD-L1 antibody inhibitors under development including CureTech’s Pidilizumab, GSK’s AMP-224 and AstraZeneca’s MEDI-4736.
  • tumor immunotherapy is considered to be a new generation of revolution in cancer treatment after targeted therapy.
  • the PD-1 monoclonal antibody currently on the market and under development has its own shortcomings, including only injections, not oral, unstable in the body, easy to be decomposed by proteases, easy to produce immune cross-reactions, purification is more difficult and production The cost is high. Therefore, small molecule inhibitors of PD-1/PD-L1 interaction are a better choice for tumor immunotherapy.
  • the purpose of the present invention is to provide a novel small molecule inhibitor of PD-1/PD-L1 interaction.

Description

含氮杂环类化合物,及其制备方法、药物组合物和应用 技术领域
本发明涉及小分子药物领域,具体地,本发明提供了一种可以用于治疗与PD-1/PD-L1信号通路有关的疾病的小分子化合物。
发明背景
免疫系统对控制及根治很多疾病起着至关重要的作用,像各种癌症、病毒引起的疾病等。但癌症细胞经常能通过一些途径躲避或抑制免疫系统,从而快速繁殖。其中一个方式就是改变免疫细胞上表达的激活和抑制分子。阻断抑制免疫检查点,像PD-1,证明是一个非常有效的抑制癌细胞的方法。
PD-1是程序性细胞死亡蛋白-1,也称之为CD279。它主要在激活的T细胞和B细胞中表达,功能是抑制细胞的激活,这是免疫系统的一种正常的自稳机制,因为过度的T/B细胞激活会引起自身免疫病,所以PD-1是我们人体的一道保护墙。PD-1是由268个氨基酸组成的I型跨膜糖蛋白,它的结构主要包括外免疫球蛋白可变区、疏水跨膜区以及胞内区。胞内区包含两个磷酸化位点,分别位于免疫受体酷氨酸抑制基序和免疫受体酷氨酸转换基序,这也证明PD-1能够反向调节T细胞受体介导的信号。PD-1有两个配体,PD-L1和PD-L2,它们在表达方式上不同。PD-L1在多种肿瘤细胞中均有上调表达,它与T细胞上的PD-1结合,抑制T细胞增殖和活化,使T细胞处于失活状态,最终诱导免疫逃逸。
PD-1/PD-L1发挥着反向免疫调节作用。当PD-1与PD-L1结合后,可致使T细胞的免疫受体酷氨酸转换基序结构域的酪氨酸多磷酸化,磷酸化的酪氨酸可结合磷酸酶蛋白酪氨酸酶2和蛋白酪氨酸酶1。这样即可阻碍细胞外信号调节激酶的活化,还可阻断磷脂肌醇3-激酶(PI3K)和丝氨酸-苏氨蛋白激酶(Akt)的激活,从而抑制T淋巴细胞增殖和相关细胞因子的分沁。PD-1/PD-L1信号抑制T细胞活化和增殖的同时,还可使细胞因子白细胞介素2、干扰素γ和IL-10的分泌。此外,PD-1/PD-L1信号对B细胞也有类似的免疫功能,当PD-1与B细胞抗原受体结合后,PD-1细胞质区与含有蛋白酪氨酸酶2结合位点的酪氨酸酶发生作用,从而阻碍B细胞的活化。
基于PD-1/PD-L1的免疫疗法是新一代备受关注的免疫疗法。最近几年,一系列令人惊喜的研究结果证实PD-1/PD-L1抑制剂对多种肿瘤具有强大的抗肿瘤活性。目前已经上市的PD-1/PD-L1抗体抑制剂有BMS的Ninolumab、Merck的Lambrolizumab以及Roche的Atezolizumab。除此之外还有很多在研的PD-1/PD-L1抗体抑制剂,包括Cure Tech的Pidilizumab、GSK的AMP-224和AstraZeneca的MEDI-4736。
虽然肿瘤免疫治疗被认为是靶向治疗后癌症治疗的新一代革命。但是目前上市和在研的PD-1单抗药有其自身的缺陷,包括只能注射给药,不能口服,在体内不稳定,易被蛋白酶分解,易产生免疫交叉反应,纯化比较困难且生产成本高等。所以PD-1/PD-L1相互作用的小分子抑制剂是肿瘤免疫治疗的更好选择。
综上所述,本领域迫切需要开发新型PD-1/PD-L1相互作用的小分子抑制剂。
