Definitions

  • the present invention relates to novel peptide inhibitors of the interleukin-23 receptor and their use in treating or preventing a variety of diseases and conditions, including inflammatory bowel disease, Crohn's disease and psoriasis.
  • the interleukin-23 (IL-23) cytokine has been implicated as playing a critical role in the pathogenesis of autoimmune diseases such as multiple sclerosis, asthma, rheumatoid arthritis, psoriasis, and inflammatory bowel disease (IBD).
  • IBD inflammatory bowel disease
  • IL-23R is expressed on a variety of adaptive and innate immune cells, including Th17 cells, ⁇ T cells, natural killer (NK) cells, dendritic cells, macrophages, and innate lymphocytes, which are abundant in the intestine.
  • IL-23R gene expression and protein levels were found to be elevated in patients with IBD.
  • TNF tumor necrosis factor
  • the produced IL-23 is enriched in the intestine, where it plays a key role in regulating the balance between tolerance and immunity through T cell-dependent and T cell-independent enteritis pathways, through its effects on helper T cell 1 (Th1) and Th17-related cytokines and inhibition of regulatory T cell responses in the intestine, which favor inflammation.
  • polymorphism of the IL-23 receptor (IL-23R) has been associated with susceptibility to inflammatory bowel disease (IBD), further establishing the key role of the IL-23 pathway in intestinal homeostasis.
  • Psoriasis is a chronic skin disease that affects 2% to 3% of the general population and has been shown to be mediated by the body's T cell inflammatory response mechanism.
  • IL-23 is one of several interleukins that is considered a key player in the pathogenesis of psoriasis, and is said to maintain chronic autoimmune inflammation through induction of interleukin-17, regulation of memory T cells, and activation of macrophages.
  • the expression of IL-23 and IL-23R has been shown to be increased in tissues of psoriasis patients, and antibodies that neutralize IL-23 show IL-23-dependent inhibition of psoriasis development in animal models of psoriasis.
  • IL-23 is a heterodimer composed of a unique p19 subunit and the p40 subunit of IL-12, which is a helper T cell 1 (TH1) development cytokine involved in the production of interferon- ⁇ (IFN- ⁇ ).
  • T cell 1 helper T cell 1
  • IFN- ⁇ interferon- ⁇
  • both IL-23 and IL-12 contain the p40 subunit, they have different phenotypic properties.
  • IL-12-deficient animals are susceptible to inflammatory autoimmune diseases, while IL-23-deficient animals are resistant, presumably because the number of CD4+T cells producing IL-6, IL-17 and TNF in the CNS of IL-23-deficient animals is reduced.
  • IL-23 binds to IL-23R, a heterodimeric receptor composed of IL-12R ⁇ 1 and IL-23R subunits.
  • IL-23 binding to IL-23R activates Jak-stat signaling molecules, Jak2, Tyk2, as well as Stat1, Stat3, Stat4, and Stat5, although activation of Stat4 is substantially weaker and forms a different DNA-bound Stat complex in response to IL-23 than IL-12.
  • IL-23R constitutively binds to Jak2 and to Stat3 in a ligand-dependent manner.
  • IL-23 preferentially acts on memory CD4(+) T cells.
  • Therapeutic moieties that inhibit the IL-23 pathway have been identified for the treatment of IL-23-related diseases.
  • a large number of antibodies that bind to IL-23 or IL-23R have been identified, including ustekinumab (a humanized antibody that binds IL-23) that has been approved for the treatment of psoriasis.
  • Peptide inhibitors that bind to IL-23R and inhibit the binding of IL-23 to IL-23R have recently been identified.
  • the present invention discloses a novel peptide inhibitor of interleukin-23 receptor, its stereoisomers or pharmaceutically acceptable salts or solvates, or pharmaceutical compositions containing them, and use of the peptide inhibitor in treating or preventing diseases or conditions including inflammatory bowel disease, Crohn's disease and psoriasis.
  • the peptide compound of the present invention has protein stability, is stable to plasma proteases, epithelial proteases, gastric and intestinal proteases, lung surface proteases, intracellular proteases, etc.; has specific targeting to IL-23; has a long plasma half-life, and has good pharmacokinetic and pharmacodynamic properties.

Description

白介素-23受体的肽抑制剂制备及其用途 技术领域
本发明涉及白介素-23受体的新型肽抑制剂及其治疗或预防多种疾病和病症的用途,所述疾病和病症包括炎症性肠病、克罗恩病和银屑病。
背景技术
白介素-23(IL-23)细胞因子已被认为在诸如多发性硬化、哮喘、类风湿性关节炎、银屑病和炎症性肠病(IBD)等自身免疫性疾病的发病机理中发挥决定性作用。急性和慢性IBD小鼠的模型研究显示IL-23R和下游效应细胞因子在疾病发病机制中起主要作用。IL-23R在多种适应性免疫细胞和固有免疫细胞上表达,所述细胞包括Th17细胞、γδT细胞、自然杀伤(NK)细胞、树突细胞、巨噬细胞和固有淋巴细胞,这些细胞在肠中大量存在。在肠粘膜表面,发现IL-23R基因表达和蛋白水平在IBD患者中升高。研究认为IL-23通过促进产生IL-6、IL-17和肿瘤坏死因子(TNF)的病原性CD4+T细胞群体的发展来介导该作用。
产生的IL-23在肠中富集,其通过对辅助性T细胞1(Th1)和Th17相关细胞因子的作用以及抑制肠中的调节性T细胞应答(其利于炎症),通过T细胞依赖性和T细胞非依赖性的肠炎通路在调节耐受性和免疫性之间的平衡中发挥关键作用。另外,IL-23受体(IL-23R)的多形现象已与炎性肠病(IBD)的易感性相关,进一步确立了IL-23路径在肠稳态中的关键作用。
银屑病为一种影响2%至3%总人群的慢性皮肤病,已表明其由身体T细胞发炎反应机制介导。IL-23是数种白细胞介素之一,被认为是银屑病发病机理的关键角色,据称其经由诱导白介素-17、调节记忆T细胞,以及活化巨噬细胞来维持慢性自身免疫性炎症。已表明IL-23和IL-23R的表达在银屑病患者组织中增加,并且中和IL-23的抗体显示银屑病动物模型中银屑病发展的IL-23依赖性抑制。
IL-23是由独特的p19亚基和IL-12的p40亚基组成的异二聚体,其是参与产生干扰素-γ(IFN-γ)的辅助性T细胞1(TH1)发展细胞因子。尽管IL-23和IL-12均含有p40亚基,但是它们具有不同的表型特性。例如,IL-12缺陷型动物易患炎症性自身免疫性疾病,而IL-23缺陷型动物具有抗性,据推测是因为IL-23缺陷型动物的CNS中产IL-6、IL-17和TNF的CD4+T细胞数减少。IL-23与IL-23R结合,所述IL-23R是由IL-12Rβ1和IL-23R亚基组成的异二聚体受体。IL-23与IL-23R的结合激活Jak-stat信号转导分子,Jak2、Tyk2以及Stat1、Stat3、Stat4和Stat5,尽管Stat4的激活实质上较弱,并且在对IL-23应答时相比于IL-12形成不同的DNA结合Stat复合物。IL-23R与Jak2组成性地结合,并且以配体依赖的方式与Stat3结合。相比于主要作用于初始CD4(+)T细胞的IL-12,IL-23优先作用于记忆性CD4(+)T细胞。
已鉴别出抑制IL-23路径的治疗部分,用于治疗IL-23相关疾病。已鉴定了与IL-23或IL-23R结合的大量抗体,包括已被批准用于治疗银屑病的乌司奴单抗(ustekinumab)(结合IL-23的人源化抗体)。最近已经鉴定了与IL-23R结合并抑制IL-23与IL-23R结合的多肽抑制剂。用乌司奴单抗和布雷奴单抗(briakinumab)(其靶向常见的p40亚基)以及tildrakizumab、guselkumab、MEDI2070和BI-655066(其靶向IL-23的独特p19亚基)进行的克罗恩病或银屑病的临床试验突出了IL-23信号转导的阻断在治疗人炎症性疾病中的潜能。虽然这些发现是有前景的,但是关于鉴定优先靶向肠中IL-23通路的稳定且选择性药剂仍具有挑战性,所述药剂可以用于治疗肠炎(包括克罗恩病、溃疡性结肠炎和相关病症)。
因此本领域仍然需要靶向IL-23通路的新疗法,其可以用来治疗和预防IL-23相关的疾病,包括与自身免疫相关的疾病。此外,特异性靶向来自肠腔侧IL-23R的化合物和方法可以为IBD患者提供治疗益处。本发明通过提供结合IL-23R以抑制与IL-23结合和信号转导并适于口服使用的新型肽抑制剂来解决这些需求。
