Definitions

  • the present invention provides a novel class of heterocyclic compounds which are synthesized and used, for example, as Syk (Spleen Tyrosine kinase) inhibitors and/or Syk-HDAC (Histone deacetylase, histone acetylase) Double inhibitor.
  • Syk Single Tyrosine kinase
  • Syk-HDAC Histone deacetylase, histone acetylase
  • Syk is a non-receptor protein tyrosine kinase that is expressed in a variety of cells, especially in various hematopoietic cells.
  • monocytes macrophages, mast cells, basophils, eosinophils, neutrophils, immature T cells, CD4 effector T cells, B cells, natural killer cells, dendritic cells, Both platelets and red blood cells are expressed.
  • expression of Syk was also detected in fibroblasts, osteoclasts, endothelial cells, and nerve cells.
  • Syk is also present in various tissues, such as epithelial cells of the lung, kidney, and cardiomyocytes. In 1991, Taniguchi et al.
  • Syk contains 629 amino acid residues consisting of two tandem Src homology domains (N-SH2 and C-SH2) at the N-terminus and a C-terminal kinase domain, which shares part of the protein kinase (ZAP-70)
  • the structure is a cytoplasmic protein kinase.
  • Syk is activated by binding of the SH2 region to a tyrosine-dependent immunoreceptor activation motif (ITAM).
  • ITAM tyrosine-dependent immunoreceptor activation motif
  • Spleen tyrosine kinase is involved in the signal transduction process of many cells, and has attracted extensive attention as a cell signal transduction factor, especially an immune signal transduction factor.
  • a cell signal transduction factor especially an immune signal transduction factor.
  • Recent studies have shown that Syk plays a key role in inhibiting cell division and proliferation, and its overactivation can promote malignant cell proliferation and inhibit apoptosis, especially B cells.
  • Syk also affects the secretion of certain cytokines, plays a key role in the production of cytokines in T cells and monocytes, bone resorption in osteoclasts, and phagocytosis of macrophages.
  • Syk also affects the maturation and activation of immune cells and is closely related to allergic and antibody-mediated autoimmune diseases.
  • Syk Since Syk is located upstream of the cellular signaling pathway, treatments that target it are more advantageous than drugs that inhibit a single downstream pathway. Therefore, Syk has been used as a therapeutic target for a variety of diseases, such as chronic inflammatory diseases such as rheumatoid arthritis, allergic diseases (allergic rhinitis and asthma), multiple sclerosis, and immune diseases (rheumatoid).
  • diseases such as chronic inflammatory diseases such as rheumatoid arthritis, allergic diseases (allergic rhinitis and asthma), multiple sclerosis, and immune diseases (rheumatoid).
  • HDAC histone acetyltransferase
  • the acetylation of histones reverses the acetylation of lysine residues of HAT and restores the positive charge of lysine residues, which facilitates the dissociation of DNA and histone octamers, and the relaxation of nucleosome structures, thus making various Transcription factors and co-transcription factors bind specifically to the DNA binding site and activate transcription of the gene. Due to the overexpression of HDAC in tumor cells, the deacetylation of histones is enhanced. By restoring the positive charge of histones and increasing the gravitation between DNA and histones, the relaxed nucleosomes become very tight, which is not conducive to specific Gene expression, including some tumor suppressor genes.
  • HDAC inhibitors can regulate the expression and stability of apoptosis and differentiation-related proteins by increasing histone acetylation in specific regions of chromatin, induce tumor cell cycle arrest and apoptosis, promote tumor cell autophagy, and inhibit The formation of tumor angiogenesis promotes the immunogenicity of tumor cells.
  • HDAC inhibitors not only become a targeted therapy for tumors, but also play a role in neurological diseases, inflammation, and promotion of autoimmunity.
  • HDAC inhibitors can also be used in combination with other anti-tumor compounds. Synergistic effect and inhibition of tumor growth, HDAC is responsible for the removal of acetyl groups on histones, and has a significant impact on gene expression, oncoprotein stability, cell migration, protein catabolism, and cell cycle regulation. .
  • Syk inhibitors or dual inhibitors of Syk-HDAC will be useful in the treatment of a variety of cancers and other diseases.

Abstract

本发明提供了一种作为Syk抑制剂和/或Syk-HDAC双重抑制剂的杂环化合物,具体地,本发明提供了一种如下式(I)所示的化合物,其中,各基团的定义如说明书中所述。本发明的化合物具有Syk抑制活性和/或Syk-HDAC双重抑制活性,可以用于治疗与Syk和/或HDAC活性或表达量相关的疾病。

Description

作为Syk抑制剂和/或Syk-HDAC双重抑制剂的杂环化合物 技术领域
本发明提供了一类新型杂环化合物,其合成及应用,例如,用作为Syk(Spleen tyrosine kinase,脾酪氨酸激酶)抑制剂和/或Syk-HDAC(Histone deacetylase,组蛋白乙酰化酶)双重抑制剂。
背景技术
Syk是一种非受体型蛋白酪氨酸激酶,在各种细胞中均有表达,尤其是在各类造血细胞中广泛表达。在单核细胞、巨噬细胞、肥大细胞、嗜碱性粒细胞、嗜酸性粒细胞、嗜中性粒细胞、未成熟T细胞、CD4效应T细胞、B细胞、自然杀伤细胞、树突细胞、血小板和红细胞均有表达。此外,在成纤维细胞、破骨细胞、内皮细胞和神经细胞中,也能检测到Syk的表达。Syk还存在于各种组织中,如肺、肾、心肌细胞的上皮细胞。1991年Taniguchi等从猪脾的cDNA中分离出分子量为72kDa的蛋白激酶,命名为Syk。Syk含有629个氨基酸残基,由N端的两个串联的Src同源结构域(N-SH2和C-SH2)和一个C端的激酶结构域组成,与蛋白激酶(ZAP-70)拥有部分的共同结构,均为胞质蛋白质激酶。Syk通过SH2区域与依赖酪氨酸的免疫受体活化基序(ITAM)结合而活化。
脾酪氨酸激酶参与很多细胞的信号转导过程,作为一种细胞信号转导因子,特别是免疫信号转导因子,受到广泛的关注。近年来研究表明,Syk对于抑制细胞的分裂和增殖等起关键作用,其过度激活可以促使恶性肿瘤细胞增殖和抑制凋亡,特别是B细胞。Syk也会影响某些细胞因子的分泌,对T细胞和单核细胞细胞因子的生成、破骨细胞的骨骼吸收以及巨噬细胞的吞噬作用等都起关键作用。Syk也会影响免疫细胞的成熟及激活,与过敏性和抗体介导的自身免疫性疾病密切相关。由于Syk位于细胞信号通路的上游,所以以其为靶点的治疗方法相对于抑制单个下游通路的药物来说,更具优势。因此Syk已被作为潜在的多种疾病的治疗靶点,比如慢性炎症性疾病如类风湿性关节炎,过敏性疾病(过敏性鼻炎和哮喘),多发性硬化症,免疫性疾病(类风湿性关节炎),多种肿瘤(乳腺癌、胃癌、直肠癌、胰腺癌、肝癌、B细胞淋巴瘤,慢性淋巴细胞白血病、非霍金斯淋巴瘤等),动脉粥样硬化(冠心病和缺血性脑卒),胃肠功能紊乱,特发性血小板减少性紫癜,Wiskott-Aldrich综合征和系统性红斑狼疮等。
HDAC是一类蛋白酶,对染色体的结构修饰和基因表达调控发挥着重要的作用。HDAC使组蛋白氨基末端的赖氨酸侧链去乙酰化,组蛋白乙酰化与组蛋白去乙酰化过程处于动态平衡,由组蛋白乙酰化转移酶(HAT)和组蛋白去乙酰化酶共同调控。组蛋白的乙酰化,逆转HAT的赖氨酸残基乙酰化作用,恢复赖氨酸残基正电荷,有利于DNA与组蛋白八聚体的解离,核小体结构松弛,从而使各种转录因子和协同转录因子能与DNA结合位点特异性结合,激活基因的转录。由于HDAC在肿瘤细胞中的过度表达,使组蛋白的去乙酰化作用增强,通过恢复组蛋白正电荷增加DNA与组蛋白之间的引力,使松弛的核小体变得十分紧密,不利于特定基因的表达,包括一些肿瘤抑制基因。
HDAC抑制剂可通过提高染色质特定区域组蛋白乙酰化,从而调控细胞凋亡及分化相关蛋白的表达和稳定性,可以诱导肿瘤细胞周期阻滞和凋亡,促进肿瘤细胞自我吞噬,还可以抑制肿瘤新生血管的生成,促进肿瘤细胞的免疫原性,HDAC抑制剂不仅成为用于肿瘤的靶向治疗,而且可以在神经性疾病,炎症,促进自身免疫等方面发挥作用。
临床前期和临床研究试验表明,HDAC抑制剂在和其他抗肿瘤化合物联用时也可以有 效的发挥协同作用,抑制肿瘤生长,HDAC负责去除组蛋白上的乙酰基团,对基因的表达,癌蛋白的稳定性,细胞迁移,蛋白质的分解代谢,和细胞周期的调控都有明显的影响。
Hagiwara,K.等于2015在Apoptosis发表的研究证实了,联合用Syk抑制剂R406和HDAC抑制剂伏立诺他对于杀死套细胞淋巴瘤细胞具有协同增强效用。
综上所述,Syk抑制剂或Syk-HDAC双重抑制剂将可用于多种癌症及其它疾病的治疗。
