Definitions

  • the present invention relates to an aromatic vinyl compound, its preparation method, intermediate, pharmaceutical composition and application thereof.
  • PD-1 programmed death 1
  • programmed death receptor 1 is an important immunosuppressive molecule. It is a member of the CD28 superfamily and was originally cloned from the apoptotic mouse T cell hybridoma 2B4.11. Immunomodulation targeting PD-1 is of great significance in anti-tumor, anti-infection, anti-autoimmune diseases and organ transplantation survival. Its ligand PD-L1 can also be used as a target, and the corresponding antibody can also play the same role.
  • PD-1/PD-L1 plays a negative immunoregulatory role.
  • PD-1 on the cell surface is coupled to PD-L1, it can lead to Tyr phosphorylation of the immunoreceptor tyrosine-based switch motif (ITSM) domain in the cytoplasmic region of T cells, and then Phosphorylated Tyr recruits the phosphatases protein tyrosinase 2 and protein tyrosinase 1, which block not only the activation of extracellular signal-regulated kinases, but also phosphatidylinositol 3-kinase (PI3K) and Activation of serine-threonine protein kinase (Akt) ultimately inhibits T lymphocyte proliferation and the secretion of related cytokines.
  • IRS immunoreceptor tyrosine-based switch motif
  • PD-1/PD-L1 signaling inhibits T cell activation and proliferation, and at the same time, the secretion of cytokines interleukin 2 (IL2), interferon gamma and IL-10 is also reduced (Eur.J.Immunol., 2002 , 32(3), 634-643.).
  • IL2 interleukin 2
  • IL-10 interferon gamma
  • PD-1/PD-L1 signaling is also similar to T cells in the immune function of B cells.
  • the cytoplasmic region of PD-1 binds with protein tyrosinase 2
  • the tyrosinase at the site acts to ultimately block the activation of B cells.
  • PD-1/PD-L1 The role of immunonegative regulator PD-1/PD-L1 in tumor immune escape has attracted more and more attention.
  • a large number of studies have confirmed that PD-L1 on the surface of tumor cells in the tumor microenvironment is increased, and at the same time, it binds to PD-1 on activated T cells and transmits negative regulatory signals, resulting in tumor antigen-specific T cells apoptosis or immune incompetence. This inhibits the immune response, which in turn promotes the escape of tumor cells.
  • PD-1/PD-L1 antibody inhibitors include BMS's Nivolumab (2014), Merck's Lambrolizumab (2014) and Roche's Atezolizumab (2016).
  • the PD-1/PD-L1 antibody inhibitors under development include Cure Tech's Pidilizumab, GSK's AMP-224 and AstraZeneca's MEDI-4736.

  • small molecule compounds can cross the cell membrane and act on intracellular targets, so they have a wide range of applications.
  • chemically modified small molecules often have good bioavailability and compliance, effectively avoiding the decomposition and inactivation of enzymes in the digestive tract.
  • the research on small molecules is also quite mature in various aspects such as production process, dosage form design and administration method.
  • the technical problem solved by the present invention is to provide a vinyl aromatic compound completely different from the prior art, its preparation method, intermediate, pharmaceutical composition and application thereof.

技术领域
本发明涉及一种芳香乙烯类化合物、其制备方法、中间体、药物组合物及其应用。
背景技术
PD-1(programmed death 1)程序性死亡受体1,是一种重要的免疫抑制分子。其为CD28超家族成员,最初是从凋亡的小鼠T细胞杂交瘤2B4.11克隆出来。以PD-1为靶点的免疫调节对抗肿瘤、抗感染、抗自身免疫性疾病及器官移植存活等均有重要的意义。其配体PD-L1也可作为靶点,相应的抗体也可以起到相同的作用。
PD-1/PD-L1发挥着负性免疫调节作用。当细胞表面的PD-1与PD-L1耦联后,可导致T细胞胞质区的免疫受体酪氨酸转换基序(Immunoreceptor Tyrosine-based Swith motifs,ITSM)结构域的Tyr磷酸化,然后磷酸化的Tyr即可募集磷酸酶蛋白酪氨酸酶2和蛋白酪氨酸酶1,不仅可阻滞细胞外信号调节激酶的活化,还可阻断磷脂酰肌醇3-激酶(PI3K)和丝氨酸-苏氨酸蛋白激酶(Akt)的激活,最终抑制T淋巴细胞增殖和相关细胞因子的分泌。PD-1/PD-L1信号可抑制T细胞活化和增殖,与此同时,细胞因子白细胞介素2(IL2)、干扰素γ和IL-10的分泌也减少(Eur.J.Immunol.,2002,32(3),634-643.)。另外,PD-1/PD-L1信号对B细胞免疫功能也类似于T细胞,当PD-1与B细胞抗原受体发生交联后,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,最终阻滞B细胞的活化。免疫负性调节分子PD-1/PD-L1在肿瘤免疫逃逸中的作用越来越引起人们的重视。大量研究证实,肿瘤微环境中的肿瘤细胞表面PD-L1增高,同时与活化的T细胞上的PD-1结合,传递负性调控信号,导致肿瘤抗原特异性T细胞的凋亡或免疫无能,从而抑制免疫反应,进而促使肿瘤细胞的逃逸。
目前已经上市的PD-1/PD-L1抗体抑制剂有BMS的Nivolumab(2014)、Merck的Lambrolizumab(2014)和罗氏的Atezolizumab(2016)。在研的PD-1/PD-L1抗体抑制剂有Cure Tech的Pidilizumab、GSK的AMP-224和阿斯利康MEDI-4736。以上这些都是生 物大分子,而小分子PD-1/PD-L1抑制剂目前还处于前期研发阶段,Curis多肽类的PD-L1小分子抑制剂AC-170(WO2012168944,WO2015033299,WO2015033301,WO2015036927,WO2015044900)刚进入临床I期,BMS苄基苯基醚类的小分子PD-1/PD-L1抑制剂(WO2015034820,WO2015160641,WO2017066227,WO2018009505,WO2018044963,WO2018118848)还在临床前研究阶段,Incyte也做了一系列的小分子PD-1/PD-L1抑制剂(WO2017070089,WO2017087777,WO2017106634,WO2017112730,WO2017192961,WO2017205464,WO2017222976,WO2018013789,WO2018044783,WO2018119221,WO2018119224,WO2018119263,WO2018219266,WO2018119286)还处在临床前研究。相较于生物大分子,小分子化合物能够穿过细胞膜作用于细胞内靶点,所以应用范围广泛。其次,小分子经化学修饰后往往具有良好的生物利用度和依从性,有效避免消化肠道中酶类的分解失活。最后,在生产工艺、剂型设计和给药方式等多种层面,小分子的研究也颇为成熟。
目前现有技术中还未出现联苯类化合物作为小分子PD-1/PD-L1抑制剂成功上市的报道,该现状亟待解决。

术语“药学上可接受的盐”是指本发明化合物与相对无毒的、药学上可接受的酸或碱制备得到的盐。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的药学上可接受的碱与这类化合物的中性形式接触的方式获得碱加成盐。药学上可接受的碱加成盐包括但不限于:锂盐、钠盐、钾盐、钙盐、铝盐、镁盐、锌盐、铋盐、铵盐、二乙醇胺盐。当本发明的化合物中含有相对碱性的官能团时, 可以通过在纯的溶液或合适的惰性溶剂中用足够量的药学上可接受的酸与这类化合物的中性形式接触的方式获得酸加成盐。所述的药学上可接受的酸包括无机酸,所述无机酸包括但不限于:盐酸、氢溴酸、氢碘酸、硝酸、碳酸、磷酸、亚磷酸、硫酸等。所述的药学上可接受的酸包括有机酸,所述有机酸包括但不限于:乙酸、丙酸、草酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、水杨酸、酒石酸、甲磺酸、异烟酸、酸式柠檬酸、油酸、单宁酸、泛酸、酒石酸氢、抗坏血酸、龙胆酸、富马酸、葡糖酸、糖酸、甲酸、乙磺酸、双羟萘酸(即4,4’-亚甲基-双(3-羟基-2-萘甲酸))、氨基酸(例如谷氨酸、精氨酸)等。当本发明的化合物中含有相对酸性和相对碱性的官能团时,可以被转换成碱加成盐或酸加成盐。具体可参见Berge et al.,"Pharmaceutical Salts",Journal of Pharmaceutical Science 66:1-19(1977)、或、Handbook of Pharmaceutical Salts:Properties,Selection,and Use(P.Heinrich Stahl and Camille G.Wermuth,ed.,Wiley-VCH,2002)。
术语“化合物”、“互变异构体”、“立体异构体”、“外消旋体”、“同位素衍生物”和它们的“药学上可接受的盐”可以以晶型或无定型的形式存在。术语“晶型”是指其中的离子或分子是按照一种确定的方式在三维空间作严格周期性排列,并具有间隔一定距离周期重复出现规律;因上述周期性排列的不同,可存在多种晶型,也即多晶型现象。术语“无定型”是指其中的离子或分子呈现杂乱无章的分布状态,即离子、分子间不具有周期性排列规律。
术语“立体异构体”是指顺反异构体或旋光异构体。这些立体异构体可以通过不对称合成方法或手性分离法(包括但不限于薄层色谱、旋转色谱、柱色谱、气相色谱、高压液相色谱等)分离、纯化及富集,还可以通过与其它手性化合物成键(化学结合等)或成盐(物理结合等)等方式进行手性拆分获得。

当任意变量(例如R A-1)在化合物的定义中多次出现时,该变量每一位置出现的定义与其余位置出现的定义无关,它们的含义互相独立、互不影响。因此,若某基团被1个、2个、3个、4个或5个R A-1基团取代,也就是说,该基团可能会被最多5个R A-1取代, 该位置R A-1的定义与其余位置R A-1的定义是互相独立的,可以是互不相同的,也可以是相同的。另外,取代基及/或变量的组合只有在该组合产生稳定的化合物时才被允许。
术语“烷基”是指具有指定的碳原子数的直链或支链烷基。
术语“烷氧基”是指基团-O-R X,其中,R X为如上文所定义的烷基。
术语“药用辅料”是指生产药品和调配处方时使用的赋形剂和附加剂,是除活性成分以外,包含在药物制剂中的所有物质。可参见中华人民共和国药典(2015年版)四部、或、Handbook of Pharmaceutical Excipients(Raymond C Rowe,2009 Sixth Edition)。
术语“预防”是指获得或发生疾病或障碍的风险降低。
术语“治疗”指治疗性疗法。涉及具体病症时,治疗指:(1)缓解疾病或者病症的一种或多种生物学表现,(2)干扰(a)导致或引起病症的生物级联中的一个或多个点或(b)病症的一种或多种生物学表现,(3)改善与病症相关的一种或多种症状、影响或副作用,或者与病症或其治疗相关的一种或多种症状、影响或副作用,或(4)减缓病症或者病症的一种或多种生物学表现发展。
术语“哺乳动物”包括任何哺乳动物。哺乳动物的实例包括但不限于牛、马、羊、猪、猫、狗、小鼠、大鼠、家兔、豚鼠、猴、人等,以人类为最优。
在不违背本领域常识的基础上,上述各优选条件,可任意组合,即得本发明各较佳实例。
本发明所用试剂和原料均市售可得。
本发明的积极进步效果在于:本发明芳香乙烯类化合物或其药学上可接受的盐对PD-1和PD-L1具有明显抑制作用,同时具有较佳的药物峰值浓度、药时曲线下面积和口服生物利用度,能够有效缓解或治疗癌症等相关疾病。
