  • IL-17B IL-17C
  • IL-17D IL-17D
  • IL-17E IL-25
  • IL-17F IL-17A
  • IL-17A is expressed by TH17 cells and is involved in the pathogenesis of inflammation and autoimmune diseases.
  • Human IL-17A is a glycoprotein with a molecular weight of approximately 17,000 Daltons.
  • IL-17A transmits signals to the cell via the IL-17 receptor complex (IL-17RA and IL-17RC) (Wright, et al.
  • IL-17A plays an important role in severe asthma and chronic obstructive pulmonary disease (COPD), but patients usually do not respond or respond poorly to currently available drugs (Al-Ramli et al. J Allergy Clin Immunol, 2009, 123:1185-1187).
  • COPD chronic obstructive pulmonary disease
  • IL-17A levels may lead to a variety of diseases, including rheumatoid arthritis (RA), bone erosion, intraperitoneal abscess, inflammatory bowel disease, allograft rejection, psoriasis, atherosclerosis, asthma and Multiple sclerosis (Gaffen, SL et al. Arthritis Research & Therapy, 2004, 6: 240-247).
  • RA rheumatoid arthritis
  • IL-17A neutralizing antibody therapy can reduce the disease incidence and severity of autoimmune encephalomyelitis ( Komiyama Y et al. J. Immunol., 2006,177:566-573).
  • the clinical trials of IL-17A antibody have shown good results on IL-7A-mediated inflammatory diseases (including asthma, psoriasis, rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis).
  • the IL-17A antibody (Cosentyx/secukinumab from Novartis) was approved by the FDA for the treatment of psoriasis in January 2015.
  • IL-17A antibodies Although a variety of IL-17A antibodies currently exist, there are few reports on specific small molecule IL-17 inhibitors with oral bioavailability. Considering the high cost of producing antibodies and the limitation of the route of administration, the development of new IL-17A small molecule inhibitors is of great significance for the development of drugs for the treatment of IL-17A-mediated diseases.
  • the purpose of the present invention is to provide a new compound and its use in preparing IL-17A inhibitors and preparing drugs for treating IL-17A-mediated diseases.

Description

一种免疫调节剂 技术领域
本发明属于制药领域,具体涉及一种免疫调节剂及其在制备药物中的用途。
背景技术
IL-17(白细胞介素-17)是促炎性细胞因子,在诱导其他炎性细胞因子、趋化因子和粘附因子中发挥作用。IL-17家族由参与急性和慢性炎症反应的细胞因子组成,包括IL-17A(CTLA-8)、IL-17B、IL-17C、IL-17D、IL-17E(IL-25)和IL-17F。IL-17A由TH17细胞表达,其参与炎症和自身免疫性疾病的病理发生。人类IL-17A是分子量约为17000道尔顿的糖蛋白。IL-17A通过IL-17受体复合物(IL-17RA和IL-17RC)将信号传送至细胞内(Wright,et al.Journal of immunology,2008,181:2799-2805)。IL-17A的主要功能是通过促炎和嗜中性粒细胞迁移细胞因子和趋化因子(包括IL-6,G-CSF,TNF-α,IL-1,CXCL1,CCL2,CXCL2)的上调来协调局部组织炎症,以及基质金属蛋白酶来允许活化的T细胞穿透细胞外基质。有研究表明IL-17A在严重哮喘和慢性阻塞性肺疾病(COPD)中发挥重要作用,但是患者通常对目前可用的药物无响应或响应不良(Al-Ramli et al.J Allergy Clin Immunol,2009,123:1185-1187)。IL-17A水平上调可能导致多种疾病,包括类风湿性关节炎(RA)、骨侵蚀、腹膜内脓肿、炎性肠病、同种异体移植物排斥反应、牛皮癣、动脉粥样硬化、哮喘和多发性硬化症(Gaffen,SL et al.Arthritis Research&Therapy,2004,6:240-247)。
研究发现,靶向IL-17A与IL-17RA的结合是治疗IL-17A介导的自身免疫性炎性疾病的有效策略。通过IL-17A中和抗体治疗,可以降低自身免疫性脑脊髓炎的疾病发病率和严重性(Komiyama Y et al.J.Immunol.,2006,177:566-573)。已有IL-17A抗体的临床试验在IL-7A介导的炎性疾病(包括哮喘、牛皮癣、类风湿性关节炎、强直性脊柱炎和多发性硬化症)上显示出良好的结果。IL-17A抗体(Novartis的Cosentyx/secukinumab)在2015年1月已被FDA批准用于牛皮癣的治疗。
尽管目前已经存在多种IL-17A抗体,但很少有关于具有口服生物利用度的IL-17小分子特异性抑制剂的报道。考虑到产生抗体的成本较高以及给药途径的限制,开发新的IL-17A小分子抑制剂对研发治疗IL-17A介导的疾病的药物具有非常重要的意义。
发明内容
本发明的目的是提供一种新的化合物及其在制备IL-17A抑制剂、制备治疗IL-17A介导的疾病的药物中的用途。
本发明提供了式I所示的化合物、或其立体异构体、或其药学上可接受 的盐:
