Definitions

  • the invention relates to the field of medicinal chemistry, and in particular to a pyridazine compound and its preparation method and use.
  • Cytokines play an important role in regulating immunity and inflammation.
  • Janus kinase is an intracellular non-receptor tyrosine kinase that mediates the transmission of various cytokine signals from extracellular to the nucleus.
  • the JAK kinase family is divided into four subtypes: JAK1, JAK2, JAK3 and TYK2. Each subtype mediates different types of cytokine signaling pathways.
  • JAK1, JAK2 and TYK2 are expressed in cells of various tissues in the human body, and JAK3 is mainly expressed in cells of various hematopoietic tissues.
  • JAK family members are composed of four JAK homology regions (JH), including a catalytically activated kinase domain (JH1), a catalytically inactive kinase-like domain (JH2), and a SH2-like domain (JH3) and four FERM domains (JH4-7).
  • JH2 domain is the most special structure. It is highly similar to the amino acid sequence of the JH1 domain. However, due to the lack of several key amino acids, it does not have phosphatase activity and therefore cannot exert catalytic activity. Therefore, It is called a kinase-like domain and plays a role in regulating catalytic activity.
  • the JAK protein coupled to the intracellular receptor is phosphorylated.
  • the activated JAK then phosphorylates the receptor.
  • the phosphorylated tyrosine site can serve as a SH2-containing structure.
  • the binding site of the protein in the SH2 domain so the signal transducer and activator of transcription (STAT) with the SH2 domain can be recruited to the receptor and phosphorylated by JAKs, and the phosphorylated STAT is formed through dimerization
  • the dimer is then transferred to the nucleus to combine with the target gene and promote its transcription, thereby regulating the growth, activation, differentiation and other functions of various cells.
  • TYK2 is the earliest discovered subtype of the JAK family. Multiple cytokine signaling pathways that require TYK2 have been discovered, including interleukin (IL) and interferon (IFN) with different subtypes. In these signaling pathways, TYK2 is coupled to transmembrane cytokine receptor proteins including IFNAR1, IL-12R ⁇ 1, IL-10R2 and IL-13R ⁇ 1, and is coupled to another receptor chain formed by JAK1 or JAK2 through heterogeneous Dimerization forms different cytokine receptor complexes, providing binding sites required for STAT binding. Different cytokines, including IFN- ⁇ , IL-6, IL-12 and IL-23, activate specific downstream STAT proteins by utilizing different cytokine receptor complexes.
  • cytokines activate helper T cells Th17, Th1, B cells or myeloid cells through the TYK2-mediated signaling pathway, including systemic lupus erythematosus, psoriasis, lupus nephritis, Sjogren's disease, Crohn's disease, systemic sclerosis, etc. Function in autoimmune diseases and chronic inflammatory diseases. Some studies show TYK2 deletion mutations can effectively inhibit the occurrence of immune diseases such as allergies, autoimmunity, and inflammation. For example, IL-23 plays a crucial role in the development of psoriasis.
  • IL-23 activates Th17 cells to secrete IL-17 and other cytokines, inducing keratinocytes to differentiate, divide and secrete IL-23. , further stimulates verification and keratinocyte proliferation to produce psoriasis.
  • TYK2 and JAK2 jointly mediate the downstream signaling pathway of IL-23. Inhibiting JAK2 can lead to anemia and other blood-related side effects. Therefore, targeting TYK2 to inhibit the IL-23 signaling pathway is a good strategy for the treatment of psoriasis.
  • the ATP-binding sites of the entire kinome members often have a high degree of homology, among which TYK2 has higher similarity with the ATP-binding sites of other members of the JAK family.
  • the full JAK family kinase inhibitors currently approved by the FDA, including tofacitinib, can act on the ATP-binding pocket of TYK2 and can also bind well to JAK1, 2, and 3 subtypes.
  • JAK1, JAK2 and JAK3 can act on the ATP-binding pocket of TYK2 and can also bind well to JAK1, 2, and 3 subtypes.
  • JAK2 activity is related to red blood cell differentiation and lipid metabolism processes
  • the above-mentioned adverse reactions such as anemia are believed to be related to Tofacitinib's insufficient selectivity for JAK2, which is caused by the drug's non-selective inhibition. Therefore, ATP-competitive TYK2 inhibitors have severe side effects that severely limit their clinical use. Finding a small molecule inhibitor with a new binding mode and highly selective specificity for TYK2 can effectively improve the therapeutic window of the drug, thereby improving its clinical use.

Description

一种哒嗪类化合物及其制备方法及用途 技术领域
本发明涉及药物化学领域,具体涉及一种哒嗪类化合物及其制备方法及用途。
背景技术
细胞因子在调节免疫及炎症的过程中发挥了重要的作用。Janus激酶(JAK)是一种胞内非受体型酪氨酸激酶,介导各种细胞因子的信号从细胞外传递到细胞核的过程。JAK激酶家族分为JAK1、JAK2、JAK3和TYK2四种亚型,各亚型分别介导不同类型的细胞因子信号通路。JAK1、JAK2和TYK2在人体各组织细胞中均有表达,JAK3主要表达于各造血组织细胞中。
JAK家族成员都由四个JAK同源区域(JAK homology regions,JH)组成,其中包括一个催化激活激酶结构域(JH1),一个无催化活性的类激酶结构域(JH2),一个类SH2结构域(JH3)以及四个FERM结构域(JH4-7)。其中JH2结构域是最为特别的一个结构,其与JH1结构域的氨基酸序列具有高度的相似性,但是由于缺少了几个关键的氨基酸其并不具有磷酸酶活性,因此不能发挥催化活性,也因此被称为类激酶结构域,并发挥调节催化活性的作用。
当细胞因子与跨膜受体结合后,与胞内受体偶联的JAK蛋白被磷酸化,活化后的JAK进而使受体被磷酸化,磷酸化的酪氨酸位点可作为含有SH2结构域的蛋白的结合位点,因此具有SH2结构域的激活转录激活蛋白(signal transducer and activator of transcription,STAT)可以被募集到受体上并被JAKs磷酸化,磷酸化的STAT通过二聚化形成二聚体后转移到细胞核内与靶基因相结合并促进其转录,进而调控多种细胞的生长、活化、分化等多种功能。
TYK2是JAK家族最早发现的一个亚型,目前已经发现多条需要TYK2参与传导的细胞因子信号通路,其中包括具有不同亚型的白介素(IL)和干扰素(IFN)。在这些信号通路中TYK2与跨膜的细胞因子受体蛋白包括IFNAR1,IL-12Rβ1,IL-10R2以及IL-13Rα1相耦联,并与另一条由JAK1或JAK2耦联形成的受体链通过异二聚化形成不同的细胞因子受体复合体,提供STAT结合所需要的的结合位点。不同的细胞因子包括IFN-α、IL-6、IL-12和IL-23等通过利用不同的细胞因子受体复合体,激活下游特定的STAT蛋白。一些细胞因子通过TYK2介导的信号通路使辅助T细胞Th17,Th1,B细胞或骨髓细胞在包括系统性红斑狼疮,银屑病,狼疮性肾炎,干燥症,克罗恩病,系统性硬化等自身免疫疾病和慢性炎性疾病中发挥功能。一些研究表明 TYK2缺失突变能有效抑制过敏,自身免疫和炎症等免疫性疾病的发生。例如,IL-23在银屑病的发生发展过程中起着至关重要的作用。最新研究表明银屑病的发病机理是内源性未知抗原激活抗原递呈细胞APC分泌IL-23,IL-23激活Th17细胞分泌IL-17等细胞因子,诱发角质细胞分化分裂和分泌IL-23,进一步刺激验证和角质细胞增殖产生银屑病。TYK2和JAK2共同介导IL-23的下游信号通路,抑制JAK2会导致贫血和其他血液相关副作用,因此靶向TYK2是抑制IL-23信号通路是治疗银屑病的良好策略。
全激酶组成员的ATP结合位点往往都具有高度的同源性,其中TYK2与JAK家族其他成员的ATP结合位点具有更高的相似性。目前FDA所批准上市的全JAK家族激酶抑制剂包括Tofacitinib等都能够作用于TYK2的ATP结合口袋,同时与JAK1,2,3亚型也能够很好的发生结合。虽然这些抑制剂对JAK1,JAK2和JAK3等其他亚型活性的抑制增强了其疗效,但是也导致了较为严重的副作用,这些不良反应包括感染、结核、肿瘤、贫血、肝损伤及胆固醇增加等。由于JAK2活性与红细胞分化及脂代谢过程相关,上述贫血等不良反应被认为可能与Tofacitinib对JAK2选择性不足有关,是该药物非选择性抑制引起的。因此,ATP竞争型的TYK2抑制剂由于其严重的副作用使得它们在临床上的使用受到了严重的限制。找到一种具有新的结合模式,能够具有TYK2高度选择特异性的小分子抑制剂能够有效提高药物的治疗窗口,从而提高其在临床上的使用。

以下通过具体试验例证明本发明的有益效果。
试验例1、化合物与激酶TYK2的JH2结构域结合实验
本发明利用体外生化实验评价了化合物对TYK2激酶的结合能力,具体实验步骤如下:
本发明所使用的人源TYK2类激酶结构域(575-869氨基酸)的表达通过昆虫细胞-杆状病毒表达系统(Bac-to-Bac Expression System)获得,具体实验步骤根据Invitrogen公司的操作手册进行。经过病毒感染66小时的Sf-9昆虫细胞在离心后使用加入蛋白酶抑制剂的质量比2.5:1的Buffer A溶液(50mM Hepes,pH 7.7,500mM NaCl,25mM imidazole,5%(v/v)glycerol,0.1%Triton X-100,0.5mM TCEP)进行溶解,超声破碎后9500rpm转速4℃离心30分钟收取上清液利用AKTA Explorer-100系统进行蛋白纯化。在将上清液通过镍亲和吸附柱的吸附洗脱(50mM Hepes,pH 7.7,500mM NaCl,350mM Imidazole,5%(v/v)glycerol,0.5mM TCEP)后再经过体积排阻色谱进行进一步纯化(50mM Hepes,pH 7.7,500mM NaCl,1mM MnCl2,5%(v/v)glycerol,0.5mM TCEP),并利用SDS-PAGE,动态光散射,液相色谱质谱等方法进行分析验证。
本发明通过均相时间分辨荧光法(HTRF)对化合物与纯化获得的激酶TYK2的JH2结构域的结合能力进行了检测。在10μL带有His标签的人源TYK2类激酶区重组蛋白中加入含有26nM荧光素标记探针和0.2nM抗6×His-terbium标记的抗体的反应体系溶液(20mM Hepes pH 7.5,150mM NaCl,10mM MgCl2,2mM DTT,50μg/mL BSA,and 0.015%Brij 35),使探针的终浓度为0.5nM,再加入不同浓度梯度的化合物,室温下孵育一小时,使用酶标仪检测HTRF信号。通过设置一组不加蛋白的对照组及一组不加化合物的对照组作为对照进行计算,得出化合物竞争性结合激酶TYK2的JH2结构域的IC50值(表1)。BMS-986165作为阳性对照。
表1.化合物竞争性结合激酶TYK2的JH2结构域的IC50

上述结果说明本发明化合物具有很好的TYK2JH2蛋白亲和力,并且一些化合物相较于阳性药BMS-986165具有更好的结合能力。
试验例2、化合物对JAK1激酶的JH2结构域结合实验
实验方案参照化合物与激酶TYK2的JH2结构域结合实验,通过HTRF实验评价化合物与JAK激酶家族成员JAK1的JH2结构域的结合能力。
本发明通过均相时间分辨荧光法(HTRF)对化合物与纯化获得的激酶JAK1的JH2结构域的结合能力进行了检测。在5μL带有His标签的人源JAK1假激酶区重组蛋白中加入含有5μL抗体,1000rpm离心30秒,再加入,再加入5μL探针,1000rpm离心30秒不同浓度梯度的化合物,室温下孵育一小时,4℃过夜后使用酶标仪检测HTRF信号。通过设置一组不加蛋白的对照组及一组不加化合物的对照组作为对照进行计算,得出化合物竞争性结合激酶JAK1的JH2结构域的IC50值(表2)。BMS-986165作为阳性对照。
表2.化合物竞争性结合激酶JAK1的JH2结构域的IC50

上述结果说明本发明化合物对JAK1JH2蛋白没有亲和作用,相较于阳性药BMS-986165具有更好的激酶选择性。
试验例3、IFN-α刺激人外周血单核细胞导致pSTAT5水平上调试验
按规定流程对健康捐献者进行取血,并经过ficoll梯度离心的方法获得外周血单核细胞(PBMCs)并进行培养。将外周血单核细胞铺入96孔板,加入不同浓度梯度的化合物,在37℃培养60分钟后再加入20ng/mL的IFN-α进行刺激,在37℃培养15分钟。以每孔1μL往每孔中加入PE耦联的抗CD3抗体进行染色并在4℃培养30分钟。将细胞转移至96孔深孔板中,以每孔1mL加入固定液,剧烈震荡混匀,在37℃水浴加热10分钟。600g转速旋转离心5分钟后用PBS洗涤细胞两次。以每孔1mL加入Perm III在4℃孵育30分钟。离心,使用分选流式细胞洗涤液(PBS,0.2%BSA,1mM EDTA)进行洗涤,加入Alexa Fluor 647耦联的pSTAT5(pY694)抗体在室温下孵育40分钟。使用分选流式细胞洗涤液洗涤两次后上样。在流式细胞仪上设门 选中CD3+细胞群后通过中位荧光强度(MFI)量化pSTAT5水平,结果如表3所示。
表3.IFN-α刺激人外周血单核细胞导致pSTAT5水平上调试验结果
上述结果说明本发明化合物能够有效抑制IFN-α刺激引起的人PBMC中TYK2信号通路的传导,并且与阳性药BMS-986165有相似的活性。
综上,本发明化合物对TYK2有良好的抑制作用,且具有良好的激酶选择性,可用于治疗与TYK2激酶功能障碍相关的疾病,如癌症、骨病、炎性疾病、免疫疾病、神经系统疾病、代谢性疾病、呼吸性疾病和心脏病等病症。本发明化合物可用于制备TYK2抑制剂以及治疗与TYK2激酶功能障碍相关的疾病的药物,具有良好的应用前景。
