Definitions

  • the present invention relates to a class of compounds or pharmaceutically acceptable salts thereof having cGAS inhibitory or antagonistic effects, and their use in the preparation of drugs for treating diseases related to abnormal cGAS expression.
  • the present invention relates to compounds represented by formula (I) and pharmaceutically acceptable salts thereof, and research on cGAS activation contributing to pathology and/or symptoms and/or conditions, diseases or disorders of subjects.
  • cGAS dsDNA receptor cyclic guanosine monophosphate-adenylate synthetase
  • cGAS dsDNA receptor cyclic guanosine monophosphate-adenylate synthetase
  • cGAMP binds to the interferon gene stimulator protein (STING) dimer on the endoplasmic reticulum and activates STING, which is then further recruited and activated by TANK binding kinase 1 (TBK1), causing downstream interferon regulatory factor 3 (IRF3) to be phosphorylated.
  • IRF3 interferon regulatory factor 3
  • Phosphorylated IRF3 forms dimers and transfers to the nucleus to induce the expression of type I interferon (IFN-I) genes.
  • STING activates nuclear factor ⁇ kinase I ⁇ , thereby phosphorylating NF- ⁇ B.
  • Phosphorylated NF- ⁇ B enters the cell nucleus and induces the expression of proinflammatory factors such as IL-6, TNF ⁇ , and IL-1 ⁇ .
  • the cGAS-STING pathway is an important component of maintaining the homeostasis of the host's innate immune system.
  • cGAS when cGAS is overactivated by highly immunogenic dsDNA, it can trigger a series of inflammatory or autoimmune diseases closely related to IFN-I release, such as rheumatoid arthritis, sepsis, acute pancreatitis, and systemic lupus erythematosus. Therefore, the development of novel and highly active cGAS inhibitors to inhibit excessive immune activation can bring good benefits to patients with inflammatory or autoimmune diseases.

Description

1,5-萘啶类cGAS抑制剂及其用途 技术领域
本发明涉及一类具有cGAS抑制或拮抗作用的化合物或其药学上可接受的盐,及其在制备治疗cGAS异常表达相关疾病的药物中的应用。具体地,本发明涉及式(I)所示的化合物及其药学上可接受的盐,及其在cGAS活化促成病理学和/或症状和/或受试者的病症、疾病或障碍的研究。
背景技术
dsDNA感受器环鸟苷酸-腺苷酸合成酶(cGAS)是一类广泛分布于固有免疫细胞和正常组织细胞胞质内的信号转导型模式识别受体,可感知来源于病原体、核或线粒体的dsDNA、mtDNA,并激活下游的炎症反应。当dsDNA被识别后,会诱发cGAS的催化中心发生构象改变,cGAS催化底物GTP和ATP,连接形成环状二核苷酸cGAMP(cyclic GMP-AMP)。接着,cGAMP与内质网上的干扰素基因刺激蛋白(STING)二聚体结合并激活STING,随后进一步招募并激活TANK结合激酶1(TBK1),使下游干扰素调节因子3(IRF3)发生磷酸化。磷酸化的IRF3形成二聚体并转移到细胞核中诱导I型干扰素(IFN-I)基因的表达。此外,STING激活核因子κ激酶Iκκ从而使NF-κB磷酸化,磷酸化的NF-κB进入细胞核诱导促炎因子如IL-6、TNFα、IL-1β表达。
cGAS–STING通路是维持宿主天然免疫系统稳态的重要组成部分。然而,当cGAS被高免疫原性dsDNA过度激活后会引发一系列与IFN-I释放密切相关的炎症或者自身免疫性疾病,如类风湿关节炎、脓毒症、急性胰腺炎和系统性红斑狼疮等。因此,开发结构新颖的高活性的cGAS抑制剂来抑制免疫过度激活,可以为炎症或者自身免疫性疾病患者带来良好收益。

当一个取代基的键可以交叉连接到一个环上的两个以上原子时,这种取代基可以与这个环上的任意原子相键合,例如,结构单元表示其取代基R可在环己基或者环己二烯上的任意一个位置发生取代。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
当所列举的连接基团没有指明其连接方向,其连接方向是任意的。
除非另有规定,当某一基团具有一个或多个可连接位点时,该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的,且可连接位点存在H原子时,则连接化学键时,该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键直形虚线键或波浪线表示。
