  • Cancer also known as malignant tumor, is one of the highest morbidity and mortality in the world. It is characterized by abnormal cell proliferation and metastasis, which spread and metastasize in a short time or relatively short time after onset.
  • Traditional treatment options include resection (if resection conditions are met), radiation therapy, and chemotherapy.
  • the targeted therapy developed in recent years has the advantages of reducing toxicity, negative effects on patients, and improving survival rate.
  • the use of targeted drugs will produce resistance for a period of time, and then the growth of cancer cells will be extremely rapid.
  • Common cancers are: blood cancer, lung cancer, liver cancer, bladder cancer, rectal cancer, stomach cancer, and so on.
  • protein kinases are a class of biologically active organisms that catalyze the transfer of the ⁇ -phosphate group of ATP to the residues of many important proteins, phosphorylate them, and thus transmit signals, thereby participating in a series of Cell activity is closely related to cell growth, differentiation and proliferation.
  • the development of selective protein kinase inhibitors to block or regulate diseases that are abnormal due to these signaling pathways has been recognized as an effective research strategy for anticancer drug development. Validated in clinical trials and multiple protein inhibitors have been approved for marketing.
  • PTKs protein tyrosine kinases
  • tyrosine kinases are the most common growth factor receptors, which are closely related to the occurrence and development of tumors.
  • the activity of tyrosine kinase is too high, leading to the activation of its downstream signaling pathway, which leads to cell transformation, proliferation, anti-apoptosis, cell survival, and ultimately the formation of tumors. Therefore, the development trend of anti-tumor drugs has begun in recent years.
  • Traditional cytotoxic drugs have turned to drugs for abnormal signal transduction in cells, and related drugs have been used in clinical practice. Compared with traditional cytotoxic anti-tumor drugs, such molecular targeted drugs have strong efficacy and little side effects, and have gradually become a hot spot in the development of anti-tumor drugs.
  • fibroblast growth factor receptors are important members of the receptor tyrosine kinase family, including four subtypes of FGFR1, FGFR2, FGFR3 and FGFR4 (Reference: (1) Turner, N Grose, R. Nature Reviews Cancer 2010, 10, 116-129. (2) Dieci MV; Arnedos M.; Andre F.; Soria JCCancer Dis covery 2013, 3, 264-279). Due to gene amplification, mutation, fusion or ligand induction, F GFR members continue to activate, induce tumor cell proliferation, invasion, migration, promote angiogenesis, promote tumor development; FGFRs are highly expressed and abnormal in various tumors.
  • Activation such as non-small cell lung cancer, breast cancer, stomach cancer, bladder cancer, endometrial cancer, prostate cancer, cervical cancer, colon cancer, esophageal cancer, keratinocyte tumor, myeloma, rhabdomyosarcoma and the like.
  • FGFR1 amplification accounts for 20% of non-small cell lung cancer squamous cell carcinoma, and studies on proliferation and signaling pathways of FGFR1-expanded lung cancer cell lines show that FGFR selective inhibitors can effectively inhibit the activation of FGFR1 signaling pathway.
  • cellular Proliferation Reference: (1) Weiss, J. et al Sci. Transl. Med. 2010, 2, 62ra93. (2) Du tt, A.
  • FGFR2 amplification accounts for 4% of refractory triple-negative breast cancer; endometrial cancer is a common gynaecological genital tumor, and FGFR2 mutation accounts for approximately 12% of endometrial cancer.
  • FGFR3 mutations accounted for 50%-60% in non-invasive bladder cancer, and FGFR3 mutations accounted for 10%-15% in invasive bladder cancer.
  • Gene rearrangement at the FGFR3t (4; 14) position in multiple myeloma accounts for 15–20%.
  • FGFR and its ligand FGFs of various subtypes in liver cancer have abnormal expression and activation, such as FGFR2, FGFR3, FGFR4, FGF19, FGF2, FGF5, FGF8, FGF9 and the like.

Description

作为FGFR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,其制备方法及作为FGFR抑制剂在治疗和防治各种疾病上的应用。
背景技术
癌症亦称恶性肿瘤,是世界上发病率最高和死亡率最高的一种疾病之一,其特点是以细胞异常增殖及转移,在发病后短时间内或相对短时间内扩散,转移。传统的治疗方案包括切除(如果符合切除条件),放疗,化疗。近年来发展起来的靶向治疗法,有降低毒性和对病人的负作用,及提高生存率等优点。但在使用靶向药物一段时间内又会产生抗药性,之后癌细胞的生长扩散就会异常迅猛。常见的癌症有:血癌,肺癌,肝癌,膀胱癌,直肠癌,胃癌,等等。
随着肿瘤分子生物学研究的深入,人们对肿瘤发生、发展的分子机制,以及不同的致病靶点的认识日益加深。在诸多涉及诱发癌症的信息传导和通路中,蛋白激酶是一类生物活性体,催化ATP的γ磷酸基转移到许多重要蛋白质的残基上,使之磷酸化,从而传递信号,进而参与一系列细胞活动,与细胞生长、分化、增殖密切相关。发展选择性的蛋白激酶抑制剂来阻断或者调控由于这些信号通路异常产生的疾病已经被视为抗肿瘤药物开发的一个有效的研究策略。在临床试验中得到验证,并有多个蛋白抑制剂被批准上市。
研究表明,作为参与细胞信号传导的最为重要的成员,蛋白酪氨酸激酶(p rotein tyrosine kinases,PTKs,简称酪氨酸激酶)是最常见的生长因子受体,与肿瘤的发生和发展密切相关。酪氨酸激酶的活性过高,导致其下游信号途径激活,从而导致细胞转化、增殖、对抗细胞调亡、促进细胞生存,最终导致肿瘤的形成;因此,近年来抗肿瘤药物的研发趋势开始从传统的细胞毒药物转向针对细胞内异常信号转导的药物,并陆续有相关药物应用于临床。与传统的细胞毒类抗肿瘤药物相比,这类分子靶向药物疗效强、毒副作用小,逐渐成为当前抗肿瘤药物研发的热点。
其中,成纤维生长因子受体(fibroblast growth factor receptors,FGFRs)是受体酪氨酸激酶家族的重要成员,主要包括FGFR1、FGFR2、FGFR3和FGFR4四种亚型(参考:(1)Turner,N.;Grose,R.Nature Reviews Cancer 2010,10,116-129.(2)Dieci M.V.;Arnedos M.;Andre F.;Soria J.C.Cancer Dis covery 2013,3,264-279)。由于基因扩增、突变、融合或配体诱导等原因,F GFR各成员持续激活,诱导肿瘤细胞增殖、侵袭、迁移,促进血管生成,促进肿瘤的发生发展;FGFRs在多种肿瘤中高表达并异常激活,如非小细胞肺癌、乳腺癌、胃癌、膀胱癌、子宫内膜癌、前列腺癌、宫颈癌、结肠癌、食管癌、角质母细胞瘤、骨髓瘤、横纹肌肉瘤等。有研究显示,FGFR1扩增占非小细胞肺癌鳞癌的20%,并通过对FGFR1扩增的肺癌细胞株体外增殖、信号通路等研究显示FGFR选择性抑制剂可以非常有效抑制FGFR1信号通路的活化和细胞的 增殖(参考:(1)Weiss,J.et al Sci.Transl.Med.2010,2,62ra93.(2)Du tt,A.et al PLoSONE 2011,6,e20351)。在乳腺癌当中,FGFR1所在的染色体(8p11–12)区域的扩增约占到ER阳性患者的10%,并且其与FGFR1mRNA的高表达以及病人的预后不良相关。FGFR2基因扩增或者突变导致FGFR2信号通路的异常激活主要与胃癌、三阴性乳腺癌、子宫内膜癌等相关。胃癌组织中FGF R2的扩增率为5%-10%(参考:Matsumoto,K.et al Br.J.Cancer,2012,106,727-32)。对313例胃癌组织分析显示,FGFR2的扩增与肿瘤大小、局部浸润程度、淋巴结转移情况以及远端转移的发生显著相关,而且具有FGFR2扩增的胃癌一般为进展性肿瘤,具有较差的预后,病人总体存活率相对较低(Jung,E.-J.et al Hum Pathol.,2012,43,1559-66.)。FGFR2扩增在难治性的三阴性乳腺癌中占到4%;子宫内膜癌是常见的妇科生殖道肿瘤,FGFR2的突变大约占到子宫内膜癌的12%。在非侵袭性膀胱癌中FGFR3突变占到50%-60%,侵袭性膀胱癌中FGFR3突变占到10%-15%。在多发性骨髓瘤中FGFR3t(4;14)位置的基因重排占到15–20%。此外,在肝癌中多种亚型的FGFR及其配体FGFs具有异常的表达及活化,如FGFR2、FGFR3、FGFR4、FGF19、FGF2、FGF5、FGF8、FGF9等。多项临床前及临床研究均表明FGF/FGFR轴线异常激活在肝癌中的重要性(Cheng,A.L.;Shen,Y.C.;Zhu,A.X.Oncology 2011,81,372-80.)。不容忽视的是,FGF/FGFR轴线的异常活化与EGFR抑制剂、新生血管抑制剂以及内分泌治疗等的耐药密切相关(Nicholas,T.;Richard,G.Nature Reviews,2010,10,116-129)。
综上所述,开发新的FGFR抑制剂将可用于多种肿瘤的治疗。
