  • the fibroblast growth factor receptor (FGFR) family belongs to a new class of receptor receptors Enzyme family, which includes four receptor subtypes (FGFR-1, FGFR-2, FGFR-3, FGFR-4) encoded by four closely related genes and some heterogeneous molecules, which interact with fibroblasts Growth factor (Fibroblast Growth Factor, FGF) and heparan sulfate form a ternary complex, which in turn triggers a series of signal transduction pathways and participates in regulating physiological processes in the organism.
  • FGF Fibroblast Growth Factor
  • heparan sulfate form a ternary complex, which in turn triggers a series of signal transduction pathways and participates in regulating physiological processes in the organism.
  • FGFR has a wide range of physiological and pathological effects in the body: (1) Embryonic development. Research shows that during embryonic development, FGFR signaling is critical for most organ development and embryonic pattern formation. (2) Cell division, migration and differentiation.
  • FGFR stimulates cell proliferation and is involved in regulating cell transformation in pathological processes. There are many parallel pathways that can achieve FGFR-mediated cell division signaling, which has been confirmed by many studies (JKWang et al., Oncogene 1997, 14, 1767 -1778.). (3) Bone diseases. The growth and differentiation of bones are also regulated by the FGF family, and mutations in FGFR can lead to skeletal deformities (R. Shang et al., Cell 1994, 78, 335-342.). (4) The occurrence of tumors. FGFR can promote endothelial cell migration, proliferation and differentiation, and plays an important role in the regulation of blood vessel formation and angiogenesis. Uncontrolled angiogenesis can lead to the occurrence of tumors and the growth of metastases (J. Folkman. Nat. Med. 1995 , 1, 27-31.).

Description

一种噻吩并嘧啶类化合物、中间体、其制备方法、组合物和应用
本申请要求申请日为2022/3/8的中国专利申请2022102209730的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及一种噻吩并嘧啶类化合物、中间体、其制备方法、组合物和应用。
背景技术
受体型酪氨酸激酶间变性淋巴瘤激酶(Anaplastic lymphoma kinase,ALK)最早发现于间变性大细胞淋巴瘤(Anaplastic large cell lymphoma,ALCL)中,由2号及5号染色体易位所形成的融合蛋白质包含了ALK的3’端胞内结构域,以及核磷蛋白(Nucleophosmin,NPM)的5’端的结构域。完整的ALK具有典型的RTK三部分结构,即胞外区、亲脂性穿膜区和胞浆内酪氨酸激酶。其细胞外区包含特殊的结合域:N端信号肽,2个甲基多巴,A5蛋白和受体蛋白酪氨酸磷酸酶μ(MAM,meprin,A5protein and receptor protein tyrosine phosphatase mu)域,1个低密度脂蛋白类A(LDLa,Low-density lipoproteinA)基序以及1个靠近细胞膜的甘氨酸富集区(G-rich,Glycine-rich)。MAM域和G-rich区可能与ALK活化有关。人类的ALK激酶区YxxxYY基序的第一个酪氨酸残基-Tyr1604,已被证明与ALK激酶区的自体活化有关(Tartari C.J.,et al.,J.Bio.Chem.,2008,283(7),3743-3750.)。
由于染色体的易位导致生成了ALK融合基因,其编码的融合蛋白形成非配体依赖性二聚体引起组成性的ALK激活。被激活的ALK信号可通过激活其下游的RAS-MEK-ERK,JAK-STAT3/5,PI3K-bKT和PLCγ信号通路导致细胞过度增殖和恶性转化。
自1994年在间变大细胞淋巴瘤(anaplastie large cell lymphoma,ALCL)研究领域首次报告ALK融合基因以来,目前已发现ALK能与多种基因融合,而这多种融合基因又与多种肿瘤的发生密切相关。如NMP-bLK融合基因就与间变性大细胞淋巴瘤(ALCL)和弥漫性大B细胞淋巴瘤(DLBCL)有关;TPM3-bLK融合基因与间变大细胞淋巴瘤(ALCL)、炎症性肌纤维母细胞瘤(IMT)、组织细胞肿瘤(Histioc.Tumor)和肾癌有关;而EML4-bLK融合基因与非小细胞性肺癌(NSCLC)、肾癌、乳腺癌及结肠癌有密切关系,并成为目前研究的热点(Lin E.,etal.,Mol.CancerRes.,2009,7,1466-1476.)。此外,在神经母细胞瘤、黑素瘤、横纹肌瘤和食管鳞状细胞瘤中都检测到了ALK融合基因(Webb T.R.,etal.,Expert Rev.AnticancerTher.,2009,9(3),331-356.)。
目前已经上市的ALK抑制剂有辉瑞的Crizotinib(WO2006021881,WO2007066185,WO2008053157)、诺华的Ceritinib(WO2012106540)和罗氏的Alectinib(WO2010143664)。研发ALK激酶抑制剂可以有效降低突变的ALK基因对下游信号通路的影响,进而影响到肿瘤细胞的侵袭和增殖等效应,最终影响肿瘤细胞的生长,起到抗肿瘤的效果。
成纤维细胞生长因子受体(Fibroblast Growth Factor Receptor,FGFR)家族属于一类新的受体激 酶家族,它包括由四种密切相关的基因所编码的四种受体亚型(FGFR-1、FGFR-2、FGFR-3、FGFR-4)及一些异构分子,它们通过与成纤维细胞生长因子(Fibroblast Growth Factor,FGF)和硫酸乙酰肝素形成三元复合物,进而引发一系列的信号传导途径,参与调节生物体内的生理过程。FGFR在体内具有广泛的生理和病理作用:(1)胚胎发育。研究表明,在胚胎的发育过程中,FGFR的信号传导对于大部分的器官发育和胚胎模式的形成都是至关重要的。(2)细胞的分裂、迁移和分化。FGFR刺激细胞增殖,同时参与调节病理过程中的细胞转化,有许多平行途径可以实现FGFR介导的细胞分裂的信号传导,这已经被许多研究所证实(J.K.Wang et al.,Oncogene 1997,14,1767-1778.)。(3)骨骼疾病。骨骼的生长和分化也受FGF家族的调控,FGFR的突变会导致骨骼畸形(R.Shang et al.,Cell 1994,78,335-342.)。(4)肿瘤的发生。FGFR能够促进内皮细胞迁移、增殖和分化,并在血管形成和血管生成的调控中发挥着重要作用,失控的血管生成会导致肿瘤的发生和转移瘤的增长(J.Folkman.Nat.Med.1995,1,27-31.)。
原肌球蛋白受体激酶(tropomyosin receptor kinase,TRK)也被称为神经营养受体酪氨酸激酶(Neurotrophic Receptor Tyrosine Kinase,NTRK)是TRK基因的产物,分子量为120~160kD。其作为一种单跨膜糖蛋白,属于受体酪氨酸激酶(receptor tyrosinekinase,RTK)家族中的成员。RTK家族成员具有类似的结构,均由胞外一个大的糖基化的配体结合区、跨膜区(TM)、胞内区(可分为近膜区、酪氨酸激酶区、羧基尾区)组成,其中胞外区含亮氨酸富集结构(leucine rich motif,LRM)和免疫球蛋白区(IgG区)。两个位于LRM旁侧的半胱氨酸簇,将TRK同酪氨酸激酶家族的其它成员相区别;而LRM决定了与配体结合的特异性。TRK受体分为TRK-A、TRK-B和TRK-C(或NTRK1、NTRK2和NTRK3)三种亚型。TRK-A、TRK-B和TRK-C激酶的异常活化可以引发众多疾病,比如癌症及自身免疫性疾病等。
