Definitions

  • the present invention relates to aromatic amine derivatives and their preparation method and medical use. Specifically, the present invention relates to a compound represented by general formula (I), its preparation method, a pharmaceutical composition containing it, and its use as a Toll-like receptor (TLR) agonist for the treatment of diseases related to TLR8 activity .
  • TLR Toll-like receptor
  • TLRs Toll-like receptors
  • TLRs are all type I transmembrane glycoproteins, consisting of an extracellular domain of 16-28 leucine-rich repeats (LRR), a transmembrane domain and a cytoplasmic Toll/IL-1 receptor (TIR) structure domain composition.
  • LRR leucine-rich repeats
  • TIR cytoplasmic Toll/IL-1 receptor
  • X-ray crystallography analysis confirmed that the TLR LRR domains were all horseshoe-like structures. So far, 11 members have been found in humans, of which TLR1, 2, 4, 5, 6, 10 and 11 are located on the cell surface, and TLR3, 7, 8, and 9 are located on the endosome membrane.
  • TLR8 and TLR7 are phylogenetically close to each other and have a high degree of sequence homology, and are located on the adjacent X chromosome (Xp22).
  • TIR domain of TLRs can recruit a variety of signaling molecules, including tumor necrosis factor receptor-related factor 6 and myeloid differentiation factor 88 (MyD88).
  • MyD88 myeloid differentiation factor 88
  • TLR8 relies on the MyD88 signaling pathway, induces the activation of protease-1 (AP-1) and nuclear factor kappa B (NF- ⁇ B) to transfer into the nucleus, induces the expression of related genes in the nucleus, secretes chemokines and inflammatory factors, etc. the role of regulation.
  • TLR8 can also activate mitogen-activated protein kinase (MAPK) signaling pathways, including p38, ERK, and JNK, which are mainly involved in the regulation of cell proliferation, cell differentiation, cell transformation, and apoptosis, and are closely related to inflammation and tumors. A variety of diseases are closely related (Journal of Immunology, 2017, 33, 813).
  • MAPK mitogen-activated protein kinase
  • Hepatitis B virus is a particulate double-stranded DNA virus. Activation of TLR8 can effectively inhibit HBV replication in vivo and in vitro, and thus becomes a target for developing treatments for chronic HBV.
  • TLRs are not only expressed on immune cells, but also in various tumor cells, participate in tumor immune surveillance, and play different roles in tumor growth. Among them, TLR8 activation enhances the activity of natural killer cells (NK cells), improves antibody-dependent cell-mediated cytotoxicity (ADCC) and induces Th1 polarization. TLR8 agonists serve as potential adjuvants in cancer therapy to induce specific immune responses against tumor cells and improve the clinical efficacy of approved monoclonal antibody therapies, especially in individuals with reduced ADCC.
  • NK cells natural killer cells
  • ADCC antibody-dependent cell-mediated cytotoxicity
  • Th1 polarization TLR8 agonists serve as potential adjuvants in cancer therapy to induce specific immune responses against tumor cells and improve the clinical efficacy of approved monoclonal antibody therapies, especially in individuals with reduced ADCC.
  • TLR-8 agonists In view of the important potential of TLR-8 agonists in the treatment of various diseases, there is an urgent need for novel TLR-8 agonists with strong activity and high selectivity.
  • the inventors have designed and synthesized a series of arylamine compounds through intensive research, which show excellent TLR8 agonistic activity and can be developed as drugs for the treatment of TLR8-related diseases.

Description

芳胺类衍生物及其制备方法和医药用途 技术领域
本发明涉及芳胺类衍生物及其制备方法和医药用途。具体地,本发明涉及通式(I)所示的化合物,其制备方法,含有其的药物组合物,以及其作为Toll样受体(TLR)激动剂用于治疗与TLR8活性相关的疾病的用途。
背景技术
Toll样受体(TLRs)是一类模式识别受体,可以识别微生物并对其产生应答。TLRs家族成员在免疫系统中起着重要作用,既是参与先天免疫的重要元件,也是连接先天免疫和特异性免疫的桥梁。该受体可以特异性地识别微生物,并启动免疫应答。
TLRs均为I型跨膜糖蛋白,由富含16-28个亮氨酸的重复序列(LRR)的胞外结构域、跨膜结构域和胞质Toll/IL-1受体(TIR)结构域组成。X射线晶体衍射分析确定TLR LRR结构域均为马蹄状结构。至今在人类已发现11个成员,其中TLR1、2、4、5、6、10和11位于细胞表面,TLR3、7、8、9位于胞内体膜上。TLR8与TLR7在种系发生上彼此接近并且具有高度的序列同源性,并位于相邻的X染色体上(Xp22)。当TLRs的LRR与配体结合后,TIR结构域构象发生改变,随后触发TLR信号通路的激活。TLR的TIR结构域可以募集多种信号分子,包括肿瘤坏死因子受体相关因子6和髓样分化因子88(MyD88)等。其中TLR8依赖MyD88信号通路,诱导激活蛋白酶-1(AP-1)和核因子κB(NF-κB)转移到核内,诱导核内相关基因的表达,分泌趋化因子和炎症因子等,发挥转录调控的作用。此外,TLR8还可以激活丝裂原活化的蛋白激酶(MAPK)信号通路,包括p38、ERK和JNK等,主要参与细胞增殖、细胞分化、细胞转化和细胞凋亡等的调节,与炎症和肿瘤等多种疾病密切相关(免疫学杂志,2017,33,813)。
乙型肝炎病毒(HBV)是一种颗粒状的双链DNA病毒。激活TLR8可以有效地抑制体内和体外乙肝病毒复制,因此成为开发治疗慢性乙型肝炎病毒的靶点。研究发现TLR8激动剂ssRNA40可以选择性地激活肝周的先天免疫细胞产生大量的IFN-γ从而抑制乙肝病毒复制,从而有潜力用作肝炎病毒感染的治疗。利用TLR8激动剂刺激PBMCs后发现可以诱导高水平的IFN-γ和TNF-α的产生,从而抑制HBV复制( Current Opinion in Virology,2018,30,9)。
TLRs不但表达于免疫细胞上,还可在各种肿瘤细胞中表达,参与肿瘤免疫监视,对肿瘤的生长发挥不同的作用。其中TLR8激活后增强自然杀伤细胞(NK cells)的活性,并提高抗体依赖的细胞调节的细胞毒性(ADCC)以及诱导Th1极化。TLR8激动剂在癌症治疗中作为一种有潜力的佐剂,目的在于诱导针对肿瘤细胞的特异性免疫应答,提高已获批准的单克隆抗体疗法临床疗效,尤其是在ADCC降 低的个体。
鉴于TLR-8激动剂具有治疗多种疾病的重要潜力,临床上对于活性强、选择性高的新型TLR-8激动剂具有迫切需求。
发明内容
本发明人经过潜心研究,设计合成了一系列芳胺类化合物,其显示出优异的TLR8激动活性,可以开发为治疗与TLR8相关的疾病的药物。
因此,本发明的目的是提供一种通式(I)所示的化合物或其立体异构体、互变异构、内消旋体、外消旋体、对映异构体、非对映异构体或其混合物形式、或其可药用盐,

本发明化合物对hTLR8和hTLR7的受体结合活性的体外分析使用从Invivogen公司购买的HEK-Bluen hTLR8和HEK-Bluen hTLR7细胞株。该细胞是在HEK293细胞中共转染hTLR8或者hTLR7基因和一个分泌型的碱性磷酸酶(SEAP)的报告基因。其中SEAP的基因是放在IFN-β最小启动子下游,IFN-β最小启动子是由5个NF-动子和AP-1结合位点组成。用hTLR8或者hTLR7的刺激剂会激活NF-剂会和AP-1启动子而产生SEAP,通过检测SEAP水平来评价化合物的作用,该检测方法为一步检测法,使用方便,常应用于高通量筛选。
试验试剂:
HEK-Blue hTLR8细胞和HEK-Blue hTLR7细胞(来源于Invivogen公司)
DMEM培养基(来源于Gibco公司)
胎牛血清(来源于Gibco公司)
HEK-Blue TM Detection,Normocino、Zeocin和杀稻瘟菌素(Blasticidine)(来源于Invivogen公司)
试验过程:
1)收取细胞培养瓶中的细胞,调整细胞密度为2.2×10 5个/mL,用HEK-Blue TM Detection检测试剂重悬细胞,向384孔板中接种45μL细胞悬液,每孔10000个细胞,
2)化合物板准备:待测化合物从2mM(或者18mM)起用DMSO稀释3倍,稀释10个梯度。取2μL稀释好的化合物加入38μL HEK-Blue TM Detection检测试剂进行20倍中间稀释。细胞加0.5%DMSO孔,作为低读值的阴性对照孔。细胞加1μM GS-9688(参考WO2016141092A1合成路线),作为高读值的阳性对照孔。
3)取5μL中间稀释好的化合物加入到已接种45L细胞的384孔板中,对药物进行10倍稀释,DMSO的终浓度为0.5%。
4)将含有细胞和化合物的384孔板放入37℃、5%CO 2的培养箱培养16小时。
5)16小时后,取出培养板,使用仪器VICTOR Nivo检测SEAP在620nm的光吸收。
6)利用GraphPad Prism 8软件分析数据,得到各化合物的EC 50
求取各浓度以及阳性和阴性对照的数据的平均值。由下式计算活性百分比:
活性%=(化合物读值-阴性孔读值)/(阳性孔读值-阴性孔读值)性孔读值。
通过使数据与非线性回归方程式拟合来计算各化合物的IC 50
Y=最低值+(最高值-最低值)/(1+10^((LogEC 50-X)*希尔斜率));
其中,X为化合物浓度的对数,Y为活性百分比。
本发明化合物对TLR8/TLR7的激动活性见下表1。
