Definitions

  • the invention belongs to the technical field of chemical medicine, and relates to a novel carbazole amide derivative having the ROR ⁇ t regulating activity of the general formula I and a preparation method thereof, and to the use of the compound for treating a disease related to ROR ⁇ t.
  • RORs Retinoic acid recetor-related orphan receptors
  • NF1R Retinoic acid recetor-related orphan receptors
  • the RORs subfamily mainly includes three members, ROR ⁇ , ROR ⁇ , and ROR ⁇ .
  • ROR ⁇ 1 and ROR ⁇ t also known as ROR ⁇ 2
  • ROR ⁇ 1 is distributed in skeletal muscle, thymus, testis, pancreas, prostate, heart and liver
  • ROR ⁇ t is only expressed in certain immune cells.
  • Th17 cells are a type of helper T cells that produce IL-17 and other pro-inflammatory cytokines. Th17 cells play a key role in many mouse autoimmune disease models, such as experimental allergic encephalomyelitis (EAE) and collagen-induced arthritis (CIA) animal models. In addition, IL-17 levels can be detected in some human autoimmune diseases including rheumatoid arthritis (RA), multiple sclerosis (MS), psoriasis (Psoriasis) and inflammatory bowel disease (IBD). Improvement. The number of Th17 cells found in tissues and peripheral blood samples of patients with autoimmune diseases increased. Therefore, Th17 cells or the cytokine IL-17 produced by them are closely related to the pathogenesis of inflammation and autoimmune diseases.
  • RA rheumatoid arthritis
  • MS multiple sclerosis
  • Psoriasis psoriasis
  • IBD inflammatory bowel disease
  • Cosentyx (Secukinumab/AIN457), a monoclonal antibody developed by Novartis that specifically blocks IL-17 treatment of psoriasis, has been approved by the FDA, which is the first in the market for psoriasis.
  • a drug that acts on IL-17 This also highlights the importance of the IL-17 signaling pathway in inflammatory diseases and demonstrates the potential for treatment of inflammatory diseases by affecting the IL-17 signaling pathway through ROR ⁇ t inhibitors.
  • ROR ⁇ t can be used as a new target for the treatment of autoimmune diseases. It is important to look for ROR ⁇ t small molecule modulators and use them in the treatment of ROR ⁇ t-mediated inflammation and autoimmune diseases.
  • Tumor immunotherapy is to control and kill tumor cells by modulating the immune system of the body, enhancing the anti-tumor immunity of the tumor microenvironment. Its target is the human immune system rather than directly targeting the tumor. Tumor immunotherapy has received much attention in recent years and is the focus of cancer treatment. It has been reported that it has demonstrated strong anti-tumor activity in the treatment of some tumor types such as melanoma and non-small cell lung cancer, and the tumor immunotherapy monoclonal antibody has been approved by the US FDA. Because of its excellent efficacy and innovation, tumor immunotherapy was named the most important scientific breakthrough of the year by Science magazine in 2013. Tumor immunotherapy is expected to become an innovation in the field of cancer treatment after surgery, chemotherapy, radiotherapy and targeted therapy.
  • Th17 cells are widely present in tumor tissues, however, nothing is known about the function of Th17 in tumor tissues.
  • Professor Dong Chen published an article in "Immunity", which mainly analyzed that Th17 cells can promote cytotoxic T cell activation and exert tumor immune function. It is found that mice with IL-17A deficiency are more prone to pulmonary melanoma (1) Cancer, if T cell therapy is used in mice, treatment with T cells secreting IL-17A can effectively prevent tumorigenesis. More importantly, with the help of IL-17A, Th17 cells show more than Th1 cells.
  • Th17 cell therapy can also effectively activate tumor-specific CD8 + T cells, of which CD8 + T cells are essential cells for anti-tumor
  • studies have shown that Th17 cells can call trees The blast cells enter the tumor tissue and allow CD8 ⁇ + dendritic cells to accumulate in the tumor tissue.
  • Th17 cells activate the tumor cell chemokine CCL20.
  • Th17 cells can effectively promote tumor-specific CD8 + T Cellular activity, these new findings broaden the horizon for tumor immunotherapy.
  • ROR ⁇ t is expressed in certain immune cells. It is reported that Th17 cells specifically express ROR ⁇ t and ROR ⁇ Activation of Th promotes the differentiation of Th17 cells and produces the pro-inflammatory cytokine IL-17. Therefore, it is theoretically possible to increase the differentiation of Th17 cells by activating ROR ⁇ t, thereby promoting the activity of tumor-specific CD8 + T cells and exerting tumor immune function.
  • ROR ⁇ t can be a potential target for tumor immunotherapy, and the search for small molecule ROR ⁇ t agonists and their use in virological infections and cancer treatment will be of great significance.

Description

咔唑酰胺类衍生物或其盐及其制备方法和用途 技术领域
本发明属于化学医药技术领域,涉及具有通式I的新的具有RORγt调节活性的咔唑酰胺类衍生物及其制备方法,还涉及这类化合物治疗与RORγt有关的疾病的用途。
背景技术
视黄酸受体相关孤儿受体(retinoic acid recetor-related orphan receptors,RORs),又称为NF1R,属于配体依赖的转录因子核受体超家族的一员。RORs亚家族主要包括RORα、RORβ和RORγ这三个成员。RORγ存在两种不同的亚型:RORγ1和RORγt(也称作RORγ2),其中RORγ1分布于骨骼肌、胸腺、睾丸、胰腺、前列腺、心脏和肝脏等处,而RORγt仅表达于某些免疫细胞中。
Littman等最早报道RORγt对于初始CD4 +T细胞分化成Th17细胞是必需的。经抗原刺激的Thp细胞向Th17细胞分化过程中,在IL-6、IL-21和TGF-β等细胞因子作用下诱导表达RORγt。从RORγt缺失小鼠中分离出来的Thp细胞,向Th17细胞株分化的能力明显降低。这些都表明RORγt是促进Th17细胞分化的关键调节因子。
Th17细胞是辅助性T细胞的一种,会产生IL-17及其他促炎性细胞因子。Th17细胞在许多小鼠自身免疫性疾病模型中均发挥了关键的作用,如实验性变态反应性脑脊髓炎(EAE)和胶原诱导性关节炎(CIA)动物模型。此外,在一些人类自身免疫性疾病包括类风湿性关节炎(RA)、多发性硬化(MS)、银屑病(Psoriasis)和炎症性肠病(IBD)中,均能检测到IL-17水平的提高。自身免疫性疾病病人的组织和外周血液样本中所发现的Th17细胞数量均增多。因此,Th17细胞或其产生的细胞因子IL-17与炎症及自身免疫性疾病的发病机制有紧密联系。
2015年1月,由诺华公司开发的通过特异性阻断IL-17治疗银屑病的单克隆抗体Cosentyx(Secukinumab/AIN457),已获FDA批准上市,这是治疗银屑病类药物市场中首个作用于IL-17的药物。这也强调了IL-17信号通路在炎性疾病中的重要性,并且展示了通过RORγt抑制剂而影响IL-17信号通路而治疗炎性疾病的潜在可能性。
因此,RORγt可作为治疗自身免疫性疾病药物的新靶点,寻找RORγt小分子调节剂并将其用于RORγt介导的炎症和自身免疫性疾病的治疗将具有重要意义。
肿瘤免疫疗法是通过调动机体的免疫系统,增强肿瘤微环境抗肿瘤免疫力,从而控制和杀伤肿瘤细胞,它的靶标是人体的免疫系统而不是直接针对肿瘤。肿瘤免疫治疗近年来备受关注,是肿瘤治疗领域的焦点。据报道,目前已在一些肿瘤类型如黑色素瘤、非小细胞肺癌等的治疗中展示出了强大的抗肿瘤活性,并已有肿瘤免疫治疗单抗药物获得美国FDA批准上市。肿瘤免疫治疗由于其卓越的疗效和创新性,在2013年被《Science》杂志评为年度最重要的科学突破。肿瘤免疫治疗有望成为继手术、化疗、放疗、靶向治疗后肿瘤治疗领域的一场革新。
目前已有研究发现,Th17细胞在肿瘤组织中广泛存在,然而,关于Th17在肿瘤组织中的功能却一无所知。2009年,董晨教授在《Immunity》上发表了一篇文章,主要解析Th17细胞可促进细胞毒性T细胞激活发挥肿瘤免疫功能,研究发现,IL-17A缺陷的小鼠更易发生肺黑色素瘤(一种癌症,如果,对小鼠采取T细胞疗法,用分泌IL-17A的T细胞治疗可有效阻止肿瘤的发生,更重要的是,在IL-17A的辅助下,Th17细胞表现出比Th1细胞更强的治疗效果,更让人意外的是,使用Th17细胞治疗还可有效激活肿瘤特异性的CD8 + T细胞,其中,CD8 + T细胞是抗肿瘤的必须细胞,研究显示,Th17细胞能召集树突细胞进入肿瘤组织,并且能使得CD8α +树突细胞聚集到肿瘤组织中。此外,Th17细胞激活肿瘤组织的趋化因子CCL20。总的来说,Th17细胞可有效促进肿瘤特异性的CD8 + T细胞的活性,这些新发现为肿瘤免疫治疗拓宽了视野。RORγt表达于某些免疫细胞中。研究报道,Th17细胞特异性表达RORγt,将RORγt激活可促进Th17细胞分化,并产生促炎性细胞因子IL-17。因此,理论上可以通过激活RORγt增加Th17细胞分化,从而促进肿瘤特异性的CD8 + T细胞的活性,发挥肿瘤免疫功能。
2015年6月9日,Celgene以8250万前期款加上2250万近期付款与Lycera就对抗癌症的T细胞药物达成协议。2015年2月,Lycera宣布已经获得大量证据表明其口服RORγ激动剂能够改善T细胞的功效,可增加IL-17的产生,促进Tc细胞活化,从而刺激对癌症细胞的免疫反应,带来持久的杀死肿瘤细胞效果;2017年1月,此药物已正式进入临床一期实验;该合作充分证明了RORγt激动剂用于肿瘤免疫疗法的巨大潜力。
因此,RORγt可作为潜在的肿瘤免疫疗法的靶点,而寻找小分子RORγt激动剂并将其用于病毒学感染和癌症治疗将具有重要意义。
