Definitions

  • This application belongs to the field of medical technology, and relates to benzene piperidine derivatives with ROR ⁇ t inhibitory activity.
  • Autoimmune diseases are mainly caused by the disorder of the immune system, especially the dysfunction of T cells, which causes the immune system to recognize abnormally and attack its own tissues or antigens.
  • Other inflammatory diseases such as allergic diseases, are mainly caused by the overreaction of the immune system to foreign antigens.
  • IL-17 cells especially Th17 cells
  • psoriasis commonly known as cowhide Moss
  • multiple sclerosis etc.
  • Th17 cells also have important pathological effects in some allergic diseases, especially neutrophil-enriched asthma (Chang et al., 2017).
  • IL-17 and Th17 cells expressing IL-17 are enriched in the tumor tissues of a variety of cancer patients (these cancers include colon cancer, lung cancer, liver cancer, breast cancer, ovarian cancer, pancreatic cancer, prostate cancer Cancer, melanoma, etc.) and may have tumor-promoting or anti-tumor effects under different conditions (Asadzadeh et al., 2017). Therefore, some inhibitors or agonists against IL-17 or Th17 cells will not only be possible to treat the above-mentioned autoimmune diseases or allergic diseases, but also be used in the clinical treatment of cancer.
  • Th17 cells are the third type of helper CD4-positive T cells after Th1 and Th2 cells discovered by Professor Dong Chen and Professor Weaver in 2005.
  • Th17 cells mainly express interleukin ((IL))-17 and IL-17F (Harrington et al., 2005; Park et al., 2005), among which IL-17 is considered to be the most important effector cytokine of Th17 cells.
  • IL-17 interleukin
  • Th17 cells can directly or indirectly recruit immune cells such as neutrophils and macrophages by secreting chemokines and cytokines to resist infection by extracellular bacteria and fungi, and by regulating the mucosal barrier Integrity has an important function in the body's mucosal immunity.
  • Abnormal and persistent Th17 cell activation can cause persistent inflammation in related tissues and organs, causing a variety of autoimmune diseases and affecting the disease progression of a variety of tumors (Asadzadeh et al., 2017).
  • Th17 cells are mainly controlled by a key primary transcription factor ROR ⁇ t, which directly regulates the expression of cytokines including IL-17 and IL-17F by binding to the sites of Th17 cell-related genes (Ivanov et al., 2006; Yang et al., 2008).
  • ROR ⁇ t also known as ROR ⁇ 2, is one of the two spliced forms of orphan receptor ROR ⁇ , ROR ⁇ 1 and ROR ⁇ 2.
  • ROR ⁇ 1 is expressed in muscle, liver, kidney and thymus tissues, while ROR ⁇ t is mainly expressed in immune cells. .
  • benzene piperidine derivatives can target ROR ⁇ t, inhibit the activity of ROR ⁇ t, the differentiation and development of Th17 cells and the expression of IL-17, and can be used to treat related autoimmune diseases, inflammatory diseases or cancers.

Description

苯甲烯哌啶衍生物及其制备方法、中间体和用途 技术领域
本申请属于医药技术领域,涉及具有RORγt抑制活性的苯甲烯哌啶衍生物。
背景技术
自身免疫性疾病主要是由于免疫系统的失调,特别是T细胞的功能紊乱,导致免疫系统异常识别、攻击自身组织或抗原造成的。其它一些炎症性疾病,譬如过敏性疾病,主要是由于免疫系统对外来抗原的过度反应造成的。过去10多年来的研究表明,表达IL-17的细胞,特别是Th17细胞的过度反应能导致多种人类自身免疫性疾病,其中包括类风湿关节炎、强直性脊柱炎、银屑病(俗称牛皮藓)、多发性硬化症等(Dong,2014)。此外,有研究表明,Th17细胞在一些过敏性疾病中,特别是中性粒细胞富集型哮喘,也具有重要的病理作用(Chang et al.,2017)。有意思的是,研究还发现IL-17和表达IL-17的Th17细胞在多种癌症病人的肿瘤组织里富集(这些癌症包括结肠癌、肺癌、肝癌、乳腺癌、卵巢癌、胰腺癌、前列腺癌、黑色素瘤等)并可能在不同的条件下具有促进肿瘤或抗肿瘤等的作用(Asadzadeh et al.,2017)。因此,针对IL-17或Th17细胞的一些抑制剂或激动剂将不仅有可能用于治疗上述自身免疫性疾病或过敏性疾病,还可用于癌症的临床治疗。
Th17细胞是由董晨教授和Weaver教授等人在2005年发现的继Th1和Th2细胞之后的第三类辅助性CD4阳性T细胞。Th17细胞主要表达白细胞介素((IL))-17和IL-17F(Harrington et al.,2005;Park et al.,2005),其中IL-17被认为是Th17细胞最主要的效应细胞因子。在正常情况下,Th17细胞能够通过分泌趋化因子和细胞因子以直接或间接的方式招募中性粒细胞、巨噬细胞等免疫细胞,抵御胞外细菌和真菌的感染,并通过调控黏膜屏障的完整性,在人体的粘膜免疫中具有重要的功能。而异常的、持续性的Th17细胞激活,则能导致相关组织和器官发生持续性的炎症反应,造成多种自身免疫性疾病并影响多种肿瘤的疾病进程(Asadzadeh et al.,2017)。
Th17细胞的分化和发育主要受一个关键的首要转录因子RORγt控制,RORγt主要通过结合到Th17细胞相关基因的位点直接调控包括IL-17和IL-17F等细胞因子的表达(Ivanov et al.,2006;Yang et al.,2008)。RORγt,也称为RORγ2,是孤儿受体RORγ的两个拼接体形式RORγ1和RORγ2之一,其中RORγ1在肌肉组合、肝脏、肾脏和胸腺组织中有一定的表达,而RORγt主要在免疫细胞中表达。研究发现,RORγt的基因缺陷,或者用小分子阻断RORγt的功能,能够导致Th17细胞的发育受阻和IL-17的表达缺陷,并对多种小鼠自身免疫性疾病模型产生抗性(不敏感),这些疾病包括小鼠实验性自身免疫性脑脊髓炎(EAE)、关节炎、银屑样皮肤炎症等(Lai and Dong,2016)。近年来,已经有多个针对IL-17和IL-17受体的单克隆药物在多种人类自身免疫性疾病的临床实验中表现出良好的治疗效果,并且被欧、美、日等国家和地区批准用于治疗中度到重度银屑病、银屑样关节病、强直性脊柱炎等慢性炎症(Lai and Dong,2016)。但是,由于单克隆抗体药物价格高昂,市场 上急需价格低廉、疗效显著且能惠及大众病人的替代药物,因此,IL-17上游的关键转录因子RORγt也成为了治疗Th17相关疾病的一个重要热门药物靶点。

实施例1人源RORγt(hRORγt)放射性配体结合分析
通过测定受试化合物和[26,27-3H]25-羟基-胆固醇(Perkin Elmer NET674250UC)在重组人源RORγt-LBD蛋白上的配体结合位点之间的竞争来评估RORγt反向激动剂在无细胞体 系中的活性。在此放射性配体竞争性结合试验中使用的蛋白质是N-6xHis-GST-RORγt-LBD(GenBank号P51449,氨基酸265-518)。
实验方法:
测定在含有150mM NaCl、5mM MgCl 2、10%甘油、2mM CHAPS、0.5mMβ-辛基吡喃葡萄糖苷、5mM DTT和50mM HEPES缓冲液(pH7.4)的96孔SPA板中进行。将待测试的化合物在DMSO中溶解,并用相同的溶剂制备化合物的半对数(3.162×)连续稀释液。将2μL DMSO溶液与28μL 8.6nM[26,27-3H]25-羟基-胆固醇和50μL 12nM RORγt LBD混合。将板以700rpm摇动20分钟,并在室温下放置10分钟,之后加入40μL Poly-Lys YSi SPA珠(多聚赖氨酸YSi SPA,每孔50μg,PerkinElmer)。将板振荡器上孵育20分钟,然后在室温下不搅拌放置10分钟,在Microbeta(PerkinElmer)上读取SPA的氚β辐射强度。用DMSO对照获得的高信号和10μM TO901317(Sigma)对RORγt观察到的最低信号计算抑制百分比值。从剂量-反应曲线上的拐点浓度拟合计算出IC 50值。

实验方法:
动物:7-9周,17-20g雌性C57BL/6小鼠。
动物免疫:在实验的首日,将MOG35-55冻干粉溶于生理盐水中,浓度为2mg/ml,然后与4mg/ml的完全弗氏佐剂(CFA)等体积混合均匀,得到乳剂。将实验动物用2%-3%异氟烷和氧的混合气体吸入麻醉后,背部剃毛后,皮下3点注射共100μL所述乳剂:一个点在两肩中点,另外两个点位于下背部中线两侧,以诱导小鼠实验性自身免疫性脑脊髓炎(EAE)。免疫后(第0天)和免疫后48小时,小鼠腹腔注射百日咳毒素(将200ng百日咳毒素溶解到200μL PBS中)。
动物给药和临床观察:动物免疫当天视为第0天。从第1天开始,连续灌胃给药25天,每天对小鼠进行临床观察和临床评分。
临床评分按照Hooke Laboratories的临床症状评分标准(Lawrence,MA,USA):
0分:正常老鼠,无明显疾病表现
1分:尾巴无力或后肢虚弱无力
2分:尾巴无力同时后肢虚弱无力
3分:后肢完全瘫痪
4分:后肢完全瘫痪同时前肢部分瘫痪
5分:濒死状态;小鼠实验性自身免疫性脑脊髓炎(EAE)致死;人道主义处死
在小鼠实验性自身免疫性脑脊髓炎(EAE)研究中,化合物18、31、46和64以10、30或者100mg/kg的剂量,每天给药两次(B.I.D)进行测试。小鼠实验性自身免疫性脑脊髓炎(EAE)实验结果显示化合物18、31、46和64能够降低临床评分。其中针对化合物31的具体实验结果请见附图1-3所示。
