Definitions

  • the invention belongs to the field of medicinal chemistry, specifically, the invention relates to benzimidazole compounds, more specifically, the invention relates to a benzimidazole compound and a preparation method thereof, as well as its use in the preparation of medicines.
  • Interleukin-1 receptor-associated kinase 4 belongs to the IRAK family, and family members also include IRAK1, IRAK2, and IRAKM (I-RAK3).
  • the human IRAK-4 gene is located in the p11.12 region of the x chromosome, encoding a 52KDa protein.
  • IRAK4 protein contains a serine-threonine kinase domain (KD) and a conserved death domain (DD) at the N-terminus.
  • TLRs Toll-like receptor
  • IL-1Rs interleukin 1 receptor
  • TLRs are a family of transmembrane pattern recognition receptors that play a central role in innate immune signaling.
  • the IL-1Rs family can initiate immune responses in response to a variety of IL-1 cytokines.
  • myeloid differentiation factor 88 acts as an adaptor protein to bind to these receptors, and IRAK4 protein is subsequently recruited to TLRs/IL-1R complexes.
  • IRAK4 can bind to MyD88 and IRAK2 through a shared death domain to form a protein complex Myddosome, which activates the kinase activity of IRAK4, resulting in downstream phosphorylation of IRAK1 and/or IRAK2.
  • IRAK1 Phosphorylation of IRAK1 causes its own conformational change, which promotes its binding to tumor necrosis factor receptor-associated factor 6 (TRAF6), thereby activating the serine-threonine kinase TAK1, activating downstream NF- ⁇ B, and initiating IL-1, IL-8, and The transcription and expression of pro-inflammatory factors such as IL-33 cause inflammatory responses.
  • TRAF6 tumor necrosis factor receptor-associated factor 6
  • IRAK4 knockout mouse models signaling and cellular responses to IL-1, IL-18, and most TLR ligands were severely impaired, confirming that IRAK4 is involved in IL-1R, IL-18R, and most TLR signaling pathways. important role in (Suzuki N, et al. Nature 2002, 416, 750-756.).
  • IRAK4 Due to the key role of IRAK4 in the cytokine signaling network, abnormally high expression or silencing of IRAK4 can induce abnormalities in the body's immune system. Among them, the abnormally high expression of IRAK4 will lead to excessive activation of the TRL/IL-1R pathway, resulting in the long-term secretion of high levels of pro-inflammatory factors in the body, causing persistent inflammatory responses, and ultimately inducing autoimmune diseases, including rheumatoid arthritis, silver Psoriasis, systemic lupus erythematosus, multiple sclerosis, etc.
  • TLR7 and TLR9 Can stimulate the production of IFN ⁇ in pDC cells, which is also considered a potential trigger of systemic lupus erythematosus (Chiang EY, et al.
  • IRAK4 has also been reported to play a key role in the occurrence and development of various malignancies, including melanoma, Waldenstrom macroglobulinemia (WM), chronic lymphocytic leukemia (CLL), acute lymphoblastic leukemia (T-ALL), ABC diffuse large B-cell lymphoma (ABC-DLCBL).

技术领域
本发明属于医药化学领域,具体的,本发明涉及苯并咪唑类化合物,更具体的,本发明涉及一种苯并咪唑类化合物及其制备方法,以及其在制备药物中的用途。
背景技术
白细胞介素-1受体相关激酶4(IRAK4)属于IRAK家族,家族成员还包括IRAK1、IRAK2、IRAKM(I-RAK3)等。人类的IRAK-4基因位于x染色体p11.12区,编码52KDa蛋白质。IRAK4蛋白与其他家族成员一样,都含有丝氨酸-苏氨酸激酶结构域(KD)和位于N端保守的死亡结构域(DD),是Toll样受体(Toll like receptor,TLRs)、白细胞介素1受体(inteleukin-1,IL-1Rs)信号通路中的关键分子,参与调控细胞内信号级联及炎症反应。TLRs是跨膜模式识别受体家族,在先天性免疫信号传递中发挥核心功能。IL-1Rs家族可在多种IL-1细胞因子刺激下启动免疫反应。
在IL-1R、IL-18R和大多数TLR受到刺激后,髓系分化因子88(MyD88)作为接头蛋白与这些受体结合,随后IRAK4蛋白被招募到TLRs/IL-1R复合物。IRAK4可与MyD88及IRAK2通过共有的死亡结构域相互结合,形成蛋白质复合体Myddosome,活化IRAK4的激酶活性,导致下游IRAK1和/或IRAK2的磷酸化。IRAK1磷酸化引起了自身构象改变,促使其与肿瘤坏死因子受体相关因子6(TRAF6)结合,从而活化丝氨酸-苏氨酸激酶TAK1,激活下游NF-κB,启动IL-1、IL-8以及IL-33等促炎性因子的转录和表达,引起炎症反应。此外,JNK信号通路也被TRAF6激活,调控炎症、细胞凋亡及细胞增殖相关基因的转录。敲除IRAK4的小鼠模型中,IL-1、IL-18和大多数TLR配体的信号转导和细胞应答均严重受损,验证了IRAK4在IL-1R、IL-18R和多数TLR信号通路中的重要作用(Suzuki N,et al.Nature 2002,416,750-756.)。
由于IRAK4在细胞因子信号网络中的关键角色,IRAK4的异常高表达或沉默都会诱使机体的免疫系统异常。其中,IRAK4异常高表达会导致TRL/IL-1R通路过度激活,使体内长期分泌高水平的促炎性因子,引起持续性的炎症反应,最终诱发自身免疫疾病,包括类风湿性关节炎、银屑病、系统性红斑狼疮、多发性硬化症等。有研究者发现类风湿性关节炎患者的 关节滑液中存在的IL-1明显高于健康者(Nouri AM,et al.Clin Exp Immunol 1984;55(2):295–302.),而进一步研究证明拮抗TLR4可降低IL-1的分泌,并在小鼠模型上有预防关节炎症的作用(Abdollahi-Roodsaz S,et al.2007;56(9):2957–67.)TLR7和TLR9的激活可刺激pDC细胞中IFNα的产生,这也被认为是系统性红斑狼疮的潜在诱因(Chiang EY,et al.J Immunol 2011;186(2):1279–88.)。许多其他自身免疫性疾病,包括炎性肠病(Coccia M,et al.J Exp Med 2012;209(9):1595–609.)、干燥综合征(Low HZ,et al.Arthritis Res Ther 2011;13(3):1–7.)等都与TLR信号增强有关,进一步提示了抑制IRAK4对自身免疫疾病的潜在药效。
IRAK4也被报道在多种恶性肿瘤的发生发展中起着关键作用,包括黑色素瘤、Waldenstrom巨球蛋白血症(WM)、慢性淋巴细胞白血病(CLL)、急性淋巴细胞白血病(T-ALL)、ABC性弥漫大B细胞淋巴瘤(ABC-DLCBL)等。MyD88-L256P的功能增强型突变造成的myddosome复合体上调,导致NF-κB的激活引起一系列肿瘤细胞系的存活及增殖。黑色素瘤活检的免疫组化结果显示磷酸化的IRAK4在病变组织中高度表达(Srivastava R,et al.Cancer Res 2012;72(23):6209–16.)。在T-ALL细胞中也观察到了IRAK1和IRAK4的mRNA表达水平的增加,以及IRAK1和IRAK4的磷酸化水平的升高(Li Z,et al.J Clin Invest 2015;125(3):1081–97.)。用shRNA沉默IRAK4或小分子抑制其酶活性会削弱来自T-ALL患者的样本中的细胞增殖,表明介由IRAK4的信号转导是疾病进展中的关键因素。还有报道称,IRAK4抑制剂与Ibrutinib(一种BTK抑制剂)联合应用,可协同抑制MyD88-L256P突变的ABC-DLBCL细胞系的增殖(Kelly PN,et al.J ExpMed 2015;212(13):2189–201.)。以上研究结果均证实了IRAK4靶点在肿瘤治疗领域的潜在价值。
此外,Fms样酪氨酸激酶(FLT3)的激活突变会导致其自身磷酸化和细胞内信号通路的启动,从而促进白血病细胞的存活和增殖,是AML产生对FLT3抑制剂适应性耐药的因素之一。有研究者已经证实,FLT3抑制剂引起FLT3-ITD突变耐药的机制,与IRAK1/4代偿性激活有关。IRAK1/4信号引起TLR通路的激活导致了自身免疫应激活化,敲低IRAK4或抑制IRAK4活性的试验证实了IRAK1/4在FLT3-ITD突变体产生适应性抵抗过程中的必需性(Melgar K,et al.Sci Transl Med 2019;508(11)),提示了同时抑制FLT3信号转导和IRAK1/4代偿性激活有治疗FLT3突变AML患者的潜力。
发明内容
本发明旨在提出一种新的IRAK4抑制剂,可用于制备治疗肿瘤相关疾病的药物。

依据原料和方法的选择,本发明化合物可以以可能的异构体中的一个或它们的混合物的形式存在,例如作为纯旋光异构体,或作为异构体混合物,如作为外消旋和非对映异构体混合物,这取决于不对称碳原子的数量。当描述具有光学活性的化合物时,使用前缀D和L或R和S来表示就分子中的手性中心(或多个手性中心)而言分子的绝对构型。前缀D和L或(+)和(–)是用于指定化合物所致平面偏振光旋转的符号,其中(–)或L表示化合物是左旋的。前缀为(+)或D的化合物是右旋的。就给定的化学结构而言,除了这些立体异构体互为镜像外,这 些立体异构体是相同的。具体的立体异构体也可称为对映异构体,并且所述异构体的混合物通常称作对映异构体的混合物。对映异构体的50:50混合物称为外消旋混合物或外消旋体,当在化学反应或方法中没有立体选择性或立体特异性时,可出现所述外消旋混合物或外消旋体。烯烃、C=N双键等的许多几何异构体也可以存在于本文所述的化合物中,且所有这种稳定的异构体在本发明中均被考虑。当本文所描述化合物含有烯双键时,除非另外说明,否则,这种双键包括E和Z几何异构体。如果化合物中含有二取代的环烷基,环烷基的取代基可能为顺式或反式(cis-或trans-)构型。
当将本发明式中与手性碳的键描写直成线时,应当理解为,手性碳的(R)和(S)两种构型和由此产生的其对映体纯的化合物和混合物两者包括在该通式范围内。本文中消旋体或者对映体纯的化合物的图示法来自Maehr,J.Chem.Ed.1985,62:114-120。除非另有说明,用楔形键和虚线键表示一个立体中心的绝对构型。
旋光性的(R)-或(S)-异构体可使用手性合成子或手性制剂制备,或使用常规技术拆分。含有不对称取代的碳原子的本发明化合物能够以旋光活性形式或外消旋形式分离。化合物的外消旋混合物的拆分可以通过本领域已知的许多方法中的任一种来进行。示例性方法包括使用手性拆分酸的分级重结晶,该手性拆分酸是旋光活性的成盐有机酸。用于分级重结晶方法的适合的拆分剂例如是旋光活性酸,例如酒石酸、二乙酰基酒石酸、二苯甲酰基酒石酸、扁桃酸、苹果酸、乳酸或各种旋光活性樟脑磺酸如β-樟脑磺酸的D和L形式。适合于分级结晶方法的其它的拆分剂包括立体异构纯形式的α-甲基-苄胺(例如,S和R形式或者非对映异构纯形式)、2-苯基甘氨醇、降麻黄碱、麻黄碱、N-甲基麻黄碱、环己基乙胺、1,2-二氨基环己烷等。外消旋混合物的拆分还可以通过在填充有旋光活性拆分剂(例如,二硝基苯甲酰基苯基甘氨酸)的色谱柱上洗脱来进行。可以采用高效液相色谱(HPLC)法也可以采用超临界流体色谱法(SFC)进行。具体方法的选择以及洗脱条件、色谱柱的选择可以由本领域技术人员根据化合物的结构以及试验结果选择。进一步的,还可以使用已知构型的光学纯的起始原料或试剂,通过立体有机合成,获得本发明所描述化合物的任何对映体或非对映体。
术语“互变异构体”是指因分子中某一原子在两个位置迅速移动而产生的官能团异构体。本发明化合物可表现出互变异构现象。互变异构的化合物可以存在两种或多种可相互转化的种类。质子移变互变异构体来自两个原子之间共价键合的氢原子的迁移。互变异构体一般以平衡形式存在,尝试分离单一互变异构体时通常产生一种混合物,其理化性质与化合物的混合物是一致的。平衡的位置取决于分子内的化学特性。例如,在很多脂族醛和酮如乙醛中,酮型占优势;而在酚中,烯醇型占优势。本发明包含化合物的所有互变异构形式。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位 素。例如,可用放射性同位素标记化合物,比如氘( 2H),氚( 3H),碘-125( 125I)或C-14( 14C)。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。

将OCI-LY10(人B细胞淋巴瘤)细胞系在37℃,5%CO 2培养体系中常规传代培养,收获在指数生长期生长的细胞并计数以进行平板接种。
用台盼蓝染色的血细胞计数器计数细胞,调整细胞浓度至适当的密度并接种于96孔板,每孔90μL细胞悬液,同时设定仅加入培养基的孔作为空白对照。将平板放置于在37℃,5%CO2培养体系中过夜,作为细胞测试板。
在96孔板中用DMSO稀释化合物,直至不同梯度浓度。
接下来,准备V底细胞培养板,每孔加入198μL测试培养基以及2μL稀释好的化合物溶液,对照孔加入2μL DMSO,用移液枪上下吹打混匀,此V底培养板作为10×浓度的化合物平板。
从化合物平板的每个单孔中,各吸取10μL化合物-培养基混合物或对照孔中的混合物,转移至细胞测试板,DMSO的终浓度为0.1%。将细胞测试板放回培养体系中静置3天,待细胞生长。
用Promega的CellTiter-Glo试剂盒(Promega-G7573)对细胞样品进行处理,在2104 EnVision plate reader上记录发光信号。计算待测化合物不同剂量下的抑制率(IR): IR(%)=(1–(RLU化合物–RLU空白)/(RLU对照–RLU空白))×100%,再计算IC50值。
