Definitions

  • the present disclosure belongs to the field of medicine, and relates to a nitrogen-containing heterocyclic derivative, a preparation method thereof and its application in medicine.
  • the present disclosure relates to the nitrogen-containing heterocyclic derivatives represented by the general formula (I), their preparation methods and pharmaceutical compositions containing the derivatives, as well as their use as TYK2 inhibitors and their preparation for treatment/ Or use in medicines for the prevention of inflammatory or autoimmune diseases.
  • Cytokine signaling plays a key role in controlling immune cell growth, differentiation, function, and communication.
  • the actions of receptor-bound Janus kinases (JAKs) and signal transducers and activators of transcription (STATs) mediate multiple cytokine signaling pathways (Cooper, GS et al., "Recent insights in the epidemiology of autoimmune diseases). :improved prevalence estimates and understanding of clustering of diseases” J. Autoimmun. 2009, 33: 197-207; Schwartz DM et al., “JAK inhibition as a therapeutic strategy for immune and inflammatory diseases” Nat Rev Drug Discov. 2017,17 :78; Schwartz DM et al., "Type I/II cytokines, JAKs, and new strategies for treating autoimmune diseases” Nat Rev Rheumatol. 2016, 12:25-36).
  • JAKs are a family of non-receptor tyrosine kinases (JAK1, JAK2, JAK3 and TYK2) associated with the intracellular domain of cell surface cytokine receptors. Upon stimulation and oligomerization of these receptors, JAK molecules are activated and phosphorylate receptor tyrosine residues to serve as docking sites for subsequent recruitment and phosphorylation of STAT proteins. Phosphorylated STAT proteins, in turn, dimerize, translocate to the nucleus and activate transcription of genes that mediate cytokine-induced responses.
  • JAK1, JAK2, JAK3 and TYK2 non-receptor tyrosine kinases
  • JAK/STAT pathways are tightly regulated, and dysfunctional JAK/STAT activity has been shown to be a hallmark of many immune and autoimmune diseases, inflammatory diseases, and cellular transformation (Schwartz DM et al., "JAK inhibition as a therapeutic strategy for immunity and inflammatory diseases” Nat Rev Drug Discov. 2017, 17:78).
  • Tyrosine kinase 2 (TYK2), the first identified member of the JAK family, is a component of various cytokine pathways leading to STAT-dependent gene transcription and cytokine-specific functional responses, including the interleukin 12/-23 family (IL-12/IL-23, with a common p40 subunit), the type I interferon (IFN) family, and the IL-6 and IL-10 families (Schwartz DM et al., "Type I/II cytokines, JAKs, and new strategies for treating autoimmune diseases” Nat Rev Rheumatol. 2016, 12:25-36). TYK2-mediated cytokine signaling plays a key role in the pathogenesis of autoimmune and inflammatory diseases.
  • IL-23 (a heterodimer containing p40 and p19 subunits) is essential for the differentiation and proliferation of T helper cells 17 (Th17), which are critically involved in several autoimmune diseases (Aggarwal, S et al., "Interleukin-23 promotes a distinct CD4 T cell activation state characterized by the production of interleukin-17" J Biol Chem. 2003, 278:1910-1914).
  • IL-12 composed of p40 and a unique p35 subunit, plays an important role in regulating Th1 development and IFN- ⁇ secretion by these cells (Metzger DW at al., "Interleukin-12 acts as an adjuvant for humoral immunity through interferon-gamma-dependent and-independent mechanisms” Eur J Immunol. 1997, 27:1958-65).
  • IL-12 and IL-23 play a role in various inflammatory diseases [such as psoriasis/psoriasis (Ps), lupus, inflammatory bowel disease (IBD), multiple sclerosis (MS), rheumatoid arthritis (RA)], etc.
  • Ps psoriasis/psoriasis
  • IBD inflammatory bowel disease
  • MS multiple sclerosis
  • RA rheumatoid arthritis
  • IFN- ⁇ , - ⁇ , - ⁇ , - ⁇ , - ⁇ , etc. members of the type I IFN family (IFN- ⁇ , - ⁇ , - ⁇ , - ⁇ , etc.) acting through the heterodimeric IFN receptor (IFNAR) are important mediators of innate and adaptive immunity, At the same time, it can also activate various elements in the immune response and enhance the expression and release of self-antigens, and become a key player in the expansion of autoimmune diseases (Lionel B.I. et al., "Regulation of type I interferon responses” Nat Rev Immunol. 2014 , 14:36–49; John C.H.
  • type I IFN in the pathogenesis of systemic lupus erythematosus (SLE) has been experimentally demonstrated, and the absence of IFNAR in a lupus-susceptible NZB mouse model largely reduces disease severity and disease mortality (Santiago- Raber ML et al., “Type-I interferon receptor deficiency reducers lupus-like disease in NZB mice” J Exp Med. 2003, 197:777-88).
  • PBMCs peripheral blood mononuclear cells
  • TYK2 inactivated or chemically inhibited in vivo were found to exhibit disease resistance in experimental autoimmune disease models such as psoriasis, multiple sclerosis, and inflammatory bowel disease (Michael P.S.
  • TYK2 SNP mutations have also been reported to be associated with SLE in Nordic, British and Chinese Han populations.
  • Genome-wide association studies found that several active loss-of-function variants of TYK2 were significantly associated with resistance to inflammatory diseases, including multiple sclerosis, psoriasis, Crohn's disease, lupus, and rheumatoid arthritis, further suggesting that TYK2 Has an important role in a wide range of autoimmune diseases.
  • Psoriasis Area and Severity Index scores decreased by more than 75% (PASI 75) in most patients and by more than 90% (PASI 90) in some patients (Kim P. et al., “Phase 2 Trial of Selective Tyrosine Kinase 2 Inhibition in Psoriasis”N Engl J Med.2018,379:1313-1321), which further illustrates the effectiveness and potential of TYK2 as a target in the field of autoimmune disease treatment.
  • TYK2 inhibitors include WO2014074661A1, WO2020086616A1, WO2020092196A1, WO2020156311A1 and the like.

含氮杂环类衍生物、其制备方法及其在医药上的应用 技术领域
本公开属于医药领域,涉及一种含氮杂环类衍生物、其制备方法及其在医药上的应用。特别地,本公开涉及通式(I)所示的含氮杂环类衍生物、其制备方法及含有该衍生物的药物组合物,以及其作为TYK2抑制剂的用途和在制备用于治疗/或预防炎性疾病或自身免疫性疾病的药物中的用途。
背景技术
细胞因子信号传导在控制免疫细胞的生长、分化、功能和交流中起关键作用。受体结合的Janus激酶(JAKs)以及信号转导和转录激活因子(STATs)的作用介导了多种细胞因子信号转导途径(Cooper,GS et al.,“Recent insights in the epidemiology of autoimmune diseases:improved prevalence estimates and understanding of clustering of diseases”J.Autoimmun.2009,33:197-207;Schwartz DM et al.,“JAK inhibition as a therapeutic strategy for immune and inflammatory diseases”Nat Rev Drug Discov.2017,17:78;Schwartz DM et al.,“Type I/II cytokines,JAKs,and new strategies for treating autoimmune diseases”Nat Rev Rheumatol.2016,12:25-36)。
JAK是与细胞表面细胞因子受体的胞内域相关的非受体酪氨酸激酶家族(JAK1、JAK2、JAK3和TYK2)。在刺激和寡聚这些受体后,JAK分子被激活并使受体酪氨酸残基磷酸化以充当停靠位点,以用于随后的STAT蛋白募集和磷酸化。反过来,磷酸化的STAT蛋白则二聚化,转运至细胞核并激活介导细胞因子诱导的应答的基因的转录。这些细胞因子介导的JAK/STAT通路受到严格调控,功能异常的JAK/STAT活性已被证明是许多免疫和自身免疫性疾病,炎性疾病以及细胞转化的标志(Schwartz DM et al.,“JAK inhibition as a therapeutic strategy for immune and inflammatory diseases”Nat Rev Drug Discov.2017,17:78)。
酪氨酸激酶2(TYK2)是JAK家族中第一个被鉴定的成员,各种细胞因子途径的组成部分,导致STAT依赖的基因转录和细胞因子的特定功能响应,包括白介素12/-23家族(IL-12/IL-23,具有共同的p40亚基),I型干扰素(IFN)家族以及IL-6和IL-10家族(Schwartz DM et al.,“Type I/II cytokines,JAKs,and new strategies for treating autoimmune diseases”Nat Rev Rheumatol.2016,12:25-36)。TYK2介导的细胞因子信号传导在自身免疫性疾病和炎性疾病的发病机制中起着关键作用。具体而言,IL-23(含有p40和p19亚基的异二聚体)对于T辅助细胞17(Th17)的分化和增殖至关重要,这些T辅助细胞是几种自身免疫性疾病的关键参与者(Aggarwal,S et al.,“Interleukin-23 promotes a distinct CD4 T cell activation state characterized by the production of interleukin-17”J Biol Chem.2003,278:1910-1914)。 由p40和独特的p35亚基组成的IL-12在调节Th1发育和这些细胞的IFN-γ分泌中起着重要的作用(Metzger DW at al.,“Interleukin-12 acts as an adjuvant for humoral immunity through interferon-gamma-dependent and-independent mechanisms”Eur J Immunol.1997,27:1958-65)。通过介导Th1/Th17反应,IL-12和IL-23在多种炎性疾病[如银屑病/牛皮癣(Ps)、狼疮、炎症性肠病(IBD)、多发性硬化症(MS)、类风湿性关节炎(RA)]中起重要作用等(Michele WL T et al.,“IL-12 and IL-23 cytokines:from discovery to targeted therapies for immune-mediated inflammatory diseases”Nat Med.2015,21:719–729;Andrew L.C et al.,“IL-23:One cytokine in control of autoimmunity”Eur.J.Immunol.2012,42:2263–2273;Craig A.M et al.,“Divergent Pro-and Anti-inflammatory Roles for IL-23 and IL-12 in Joint Autoimmune Inflammation”J.Exp.Med.2003,198:1951-1957)。例如,在小鼠模型中,发现IL-12和IL-23的共同亚基P40或共有受体IL23R阻断或缺失可保护小鼠免受各种自身免疫性疾病(银屑病/牛皮癣、狼疮、炎症性肠病、多发性硬化症、类风湿性关节炎等)的侵害(Kyttaris VC et al.,“Cutting edge:IL-23 receptor deficiency prevents the development of lupus nephritis in C57BL/6-lpr/lpr mice”J Immunol.2010,184:4605-9;Paulina K et al.,“IL-12 protects from psoriasiform skin inflammation”Nat Commun.2016,7:13466;Hong K et al.,“IL-12,independently of IFN-gamma,plays a crucial role in the pathogenesis of a murine psoriasis-like skin disorder”J Immunol.1999,162:7480-91)。在人类疾病中,银屑病患者的病变皮肤中观察到高水平的IL-12和IL-23,然后在银屑病的各种治疗后水平下降(Lee E at al.,“Increased expression of interleukin 23 p19 and p40 in lesional skin of patients with psoriasis vulgaris”J Exp Med.2004,199:125-30)。此外,已证明阻断IL-12/IL-23共同亚基p40(Ustekinumab,Briakinumab等)或IL-23特异性亚基p19(Tildrakizumab,Risankizumab等)的单克隆抗体在治疗银屑病方面具有临床疗效,克罗恩氏病等(Gandhi M at al.,“Anti-p40 antibodies ustekinumab and briakinumab:blockade of interleukin-12 and interleukin-23 in the treatment of psoriasis”Semin Cutan Med Surg.2010,29:48-52;Bram V et al.,“New treatment options for inflammatory bowel diseases”J Gastroenterol.2018,53:585)。同时,通过异二聚体IFN受体(IFNAR)发挥作用的I型IFN家族成员(IFN-α、-β、-ε、-κ、-ω等)是先天免疫和适应性免疫的重要介质,同时也能激活免疫应答中的多种元件及增强自身抗原表达和释放,而成为自身免疫疾病扩增的关键参与者(Lionel B.I.et al.,“Regulation of type I interferon responses”Nat Rev Immunol.2014,14:36–49;John C.H.et al.,“Type I interferons:crucial participants in disease amplification in autoimmunity”Nat Rev Rheumatol.2010,6:40–49;Antonios P et al.,“Type I interferon–mediated autoimmune diseases:pathogenesis,diagnosis and targeted therapy”Rheumatology 2017,10:1662-1675)。I型IFN在系统性红斑狼疮(SLE)发病机理中的重要性已通过实验证实,狼疮易感NZB小鼠模型中,IFNAR的缺失很大程度上减轻了疾病严重程度及疾病致死率(Santiago-Raber ML et al., “Type-I interferon receptor deficiency reduces lupus-like disease in NZB mice”J Exp Med.2003,197:777-88)。在人类SLE患者中,在很多患者中发现了血清IFNα水平升高以及I型IFN调控基因在外周血单核细胞(PBMC)和受影响器官中的表达水平升高。此外,其他一些研究也报道I型干扰素的激活与SLE的疾病程度密切相关(Bengtsson AA et al.,“Activation of type I interferon system in systemic lupus erythematosus correlates with disease activity but not with antiretroviral antibodies”Lupus.2000,9:664-71)。
多项研究证据表明TYK2在上述自身免疫性疾病发病机理中的重要性。例如,发现体内TYK2失活或受化学抑制的啮齿动物在银屑病,多发性硬化症和炎症性肠病等实验性自身免疫疾病模型中表现出抗病力(Michael P.S.et al.,“The Interleukin-23/Interleukin-17 Axis Links Adaptive and Innate Immunity in Psoriasis”Front.Immunol.2018,10:3389;Ishizaki M et al.,“Involvement of tyrosine kinase-2 in both the IL-12/Th1 and IL-23/Th17 axes in vivo.”J Immunol.2011,187:181-9)。人群研究发现,在墨西哥Mestizo人群中,携带TYK2活性缺失变体(如rs12720356和rs34536443)的儿童和成年人SLE发生减少(Cecilia C.C.et al.,“Catalytically Impaired TYK2 Variants are Protective Against Childhood-and Adult-Onset Systemic Lupus Erythematosus in Mexicans”Scientific Reports.2019,9:12165)。此外,在北欧,英国和中国汉族人群中,TYK2 SNP突变也报道与SLE相关。全基因组关联研究(GWAS)发现TYK2的几种活性缺失变体与抵抗炎症性疾病显著相关,包括多发性硬化症、银屑病、克罗恩病、狼疮和类风湿性关节炎,进一步表明TYK2在广泛的自身免疫疾病中具有重要作用。(Westra HJ et al.,“Fine-mapping and functional studies highlight potential causal variants for rheumatoid arthritis and type 1 diabetes”Nat Genet.2018,50:1366-1374;Okada Y et al.,“Genetics of rheumatoid arthritis contributes to biology and drug discovery”Nature.2014,506:376-81;Mero IL et al.,“A rare variant of the TYK2 gene is confirmed to be associated with multiple sclerosis”Eur J Hum Genet.2010,18:502-4;Peluso C et al.,“TYK2 rs34536443 polymorphism is associated with a decreased susceptibility to endometriosis-related infertility”Hum Immunol.2013,74:93-7;Gorman JA et al.,“The TYK2-P1104A autoimmune protective variant limits coordinate signals required to generate specialized T cell subsets”Front Immunol.2019,25;10:44)。由此可见,开发抑制TYK2介导的细胞因子信号传导途径作用的药物针对人类自身免疫性疾病有潜在的治疗益处。实际上,已显示出高度选择性的变构TYK2抑制剂BMS986165可有效阻断IL-12/IL-23和I型IFN信号通路,从而在多种实验性自身免疫疾病模型(银屑病、SLE和IBD)中显示出显著药效(Tokarski JS et al.,“Tyrosine Kinase 2-mediated Signal Transduction in T Lymphocytes Is Blocked by Pharmacological Stabilization of Its Pseudokinase Domain”J Biol Chem.2015,290:11061-74)。此外,2期临床试验结果报道,该药物在中度至重度斑块状银屑病患者中达到疗效主要终点,且有良好的风险效益比。在服用 BMS986165 12周后,多数患者的银屑病面积和严重指数评分下降超过75%(PASI 75),有些患者PASI评分下降超过90%(PASI 90)(Kim P.et al.,“Phase 2 Trial of Selective Tyrosine Kinase 2 Inhibition in Psoriasis”N Engl J Med.2018,379:1313-1321),进一步说明了TYK2这一靶点在自身免疫性疾病治疗领域的有效性及潜力。

KdELECT竞争结合测定法由CRO,Eurofins DiscoverX Corporation按照既定的标准协议(DiscoverX,圣地亚哥,加利福尼亚)进行。简而言之,在衍生自BL21菌株的大肠杆菌宿主中制备了激酶标记的T7噬菌体菌株。使大肠杆菌生长至对数期并用T7噬菌体感染,并在32℃摇动孵育直至裂解。将裂解物离心并过滤以除去细胞碎片。其余的激酶在HEK-293细胞中产生,随后用DNA标记以进行qPCR检测。在室温下,用生物素化的小分子配体处理链霉亲和素包被的磁珠30分钟,以生成用于激酶测定的亲和树脂。用过量的生物素封闭配体珠,并用封闭缓冲液(SeaBlock(Pierce),1%BSA,0.05%吐温20,1mM DTT)洗涤,以除去未结合的配体并减少非特异性结合。通过在1x结合缓冲液(20%SeaBlock,0.17×PBS,0.05%吐温20,6mM DTT)中结合激酶,配体亲和珠和测试化合物来组装结合反应。将测试化合物制成100%DMSO中的111倍-储备液。使用具有三个DMSO对照点的化合物3倍稀释,共11个剂量,确定Kds。用于Kd测量的所有化合物均通过声学转移(非接触式点胶)分配到100%DMSO中。然后将化合物直接稀释到测定中,以使DMSO的最终浓度为0.9%。所有反应均在聚丙烯384孔板上进行。每个终体积为0.02mL。将测定板在室温下振荡孵育1小时,并用洗涤缓冲液(1×PBS,0.05%吐温20)洗涤亲和珠。然后将珠子重悬于洗脱缓冲液(1×PBS,0.05%吐温20、0.5μM非生物素化的亲和配体)中,并在室温下振摇孵育30分钟。通过定量PCR测量洗脱液中的激酶浓度。
化合物处理:在100%最终测试浓度下,在100%DMSO中制备每种测试化合物的稀释液,3倍稀释,共11个剂量,然后在测定中稀释至1倍(最终DMSO浓度=1%)。使用化合物最高浓度=30,000nM来确定大多数Kd。如果确定的初始Kd<0.5nM(测试的最低浓度),则以从较低的最高浓度开始的系列稀释液重复进行测量。报告的Kd值为40,000nM,表明Kd被确定为>30,000nM。
