Definitions

  • the present invention relates to a novel pyrimidine derivative, a process for its preparation and a pharmaceutical composition containing the same and its use as a therapeutic agent, in particular as an FGFR4 inhibitor.
  • the fibroblast growth factor receptor (FGFR) family is composed of four members (FGFR1, FGFR2, FGFR3, and FGFR4), which are kinases of the receptor tyrosine kinase family, and FGF binding leads to FGFR dimerization, followed by Autologous phosphorylation and activation of downstream signaling pathways. Receptor activation is sufficient to regenerate and activate specific downstream signaling partners involved in the regulation of diverse processes such as cell growth, cell metabolism, and cell survival. Therefore, the FGF/FGFR signaling pathway has multiple effects in many biological processes for tumor cell proliferation, migration, invasion, angiogenesis, and cell criticality.
  • the four members of the FGFR family differ from each other in terms of their ligand affinity and tissue distribution.
  • the genomic structure of the FGFR-4 gene contains 18 exons.
  • the human FGF19 gene is located at 11q13.1, and FGFR4 specifically binds to its ligand FGF19 to inhibit apoptosis and NF-kB signaling, and up-regulate expression of cell proliferation-related genes; activation of FGFR4 can cause Ikk ⁇ activity in TNF- ⁇ -treated cells The decrease is accompanied by a decrease in the distribution of NF-kB in the cell and attenuating the apoptotic effect.
  • Four FGFR genes are expressed in human liver, but mature hepatic cells (Hepatpcyte) only express FGFR4 in large amounts. The combination of FGFR4 and its ligand can also regulate the metabolism of bile acids.
  • the balance of cholesterol to bile acid conversion in the body is closely related to various normal physiological functions of the body. This balance of damage can cause various diseases such as fat in the body. Cardiovascular and cerebrovascular diseases such as liver and arteriosclerosis, so the interaction of FGFR4 and FGF19 becomes a new target for cholesterol-lowering drugs such as hyperlipidemia.
  • FGFR1 has gene mutations in breast cancer, non-small cell lung cancer, and glioblastoma.
  • fusion proteins are formed by gene transposition, in pancreatic cancer, bladder cancer, Overexpression in prostate cancer and esophageal cancer;
  • FGFR2 has mutations and amplification in gastric cancer, breast cancer and uterine cancer, and is also found in prostate cancer, esophageal cancer, ovarian cancer, pancreatic cancer, brain tumor, and colorectal cancer.
  • FGFR3 has gene mutations in multiple myeloma and bladder cancer, overexpressed in ovarian cancer, non-small cell lung cancer, hepatocellular carcinoma; FGFR4 in lung cancer, ovarian cancer, prostate cancer, liver cancer and cholangiocarcinoma There are mutations and overexpression, and there is also excessive expression in thyroid cancer, ovarian cancer, etc. (French et al. 2012 PLos ONE 7(5): e367313; Sia et al. 2013 Gastroejterology 144: 829-840).

Description

嘧啶类衍生物、其制备方法和其在医药上的用途 发明领域
本发明涉及一种新的嘧啶类衍生物、其制备方法及含有该衍生物的药物组合物以及其作为治疗剂特别是作为FGFR4抑制剂的用途。
发明背景
成纤维细胞生长因子受体(FGFR)家族是由四个成员(FGFR1、FGFR2、FGFR3和FGFR4)组成,其属于受体酪氨酸激酶家族的激酶,FGF结合导致FGFR二聚化,随后为受体自体磷酸化和下游信号通路的激活。受体活化足以复元和活化参与如细胞生长、细胞新陈代谢和细胞存活的多元化过程调控的特定下游信号伙伴。因此,在对于肿瘤细胞增殖、迁移、浸润、血管形成、细胞关键性的许多生物过程中,FGF/FGFR信号通路具有多效应作用。FGFR家族的四个成员在其配体亲和力及组织分布方面彼此不同。FGFR-4基因的基因组结构含有18个外显子。
人类FGF19基因位于11q13.1,FGFR4与其配体FGF19特异性结合抑制细胞凋亡和NF-kB信号,并且上调细胞增殖相关基因的表达;FGFR4的激活在TNF-α处理的细胞中可以导致Ikkβ活性的下降,伴随NF-kB在细胞中分布的减少并且减弱细胞凋亡效应。四种FGFR基因在人体肝脏中均有表达,但成熟肝实质细胞(Hepatpcyte)仅大量表达FGFR4。FGFR4与其配体结合还可以对胆汁酸的代谢有调控作用,机体中胆固醇向胆汁酸转化的平衡与机体多种正常生理功能有密切的关系,这一平衡的破坏会引起机体多种疾病如脂肪肝和动脉硬化等心脑血管疾病,因此FGFR4和FGF19相互作用成为高脂血症等降胆固醇药物的新的靶标。
近年来,越来越多的证据表明,在多种类型的癌症中有FGFR1、FGFR2、FGFR3和FGFR4的基因扩增突变。大量的证据表明:FGFR1在乳腺癌、非小细胞性肺癌和成胶质细胞瘤中有基因突变,在急性骨髓性白血病中有由基因转座导致的融合蛋白形成,在胰腺癌、膀胱癌、前列腺癌、食道癌中有过量表达;FGFR2在胃癌、乳腺癌和子宫癌中有基因突变和扩增的现象,同时在前列腺癌、食道癌、卵巢癌、胰腺癌、脑瘤、大肠癌中有过量表达;FGFR3在多发性骨髓瘤和膀胱癌中有基因突变,在卵巢癌、非小细胞性肺癌、肝细胞癌中有过量表达;FGFR4在肺癌、卵巢癌、前列腺癌、肝癌和胆管癌等中有突变和过量表达,在甲状腺癌、卵巢癌等中也有过量的表达(French et al.2012PLos ONE 7(5):e367313;Sia et al.2013 Gastroejterology 144:829-840)。
目前已经公开了一系列的FGFR抑制剂专利,但对于FGFR4选择性抑制的专利公开较少,对于FGFR4选择性的抑制剂,相对于FGFR抑制剂具有毒性小的优势(Brown,AP et al(2005),Toxocol.Pathol.,449-455)。目前处于临床的FGFR4抑制剂,包括FGF-401(诺华,临床II期)、BLU-554(Blueprint,临床I期)和H3B6527(卫材,临床I期)。FGFR4选择性抑制的专利包括WO2015059668、WO2015057938和WO2015057963等,目前对于FGFR4抑制剂对于抗肝癌等肿瘤的研究是远远不够的,仍有必要研究和开发新的FGFR4抑制剂。

测试例1、本发明化合物对FGFR激酶活性测定
以下方法用于测定本发明化合物在体外条件下对重组人源FGFR蛋白的激酶活性的抑制程度。本方法使用Cisbio公司的
Figure PCTCN2017085135-appb-000027
酪氨酸激酶试剂盒(货号62TK0PEB),该试剂盒原理基于时间分辨荧光能量共振转移(TF-FRET),通过测定FGFR蛋白介导的生物素化的多肽底物的磷酸化程度来反映化合物对FGFR激酶活性的抑制强弱。详细实验操作可参考试剂盒说明书。重组人源FGFR蛋白购于Carna bioscience(日本,货号分别为FGFR1#08-133,FGFR2#08-134,FGFR3#08-135,FGFR4#08-136)。
将实验流程简述如下:受试化合物首先溶解于DMSO中制备为贮存液,随后以试剂盒中提供的缓冲液进行梯度稀释,受试化合物在反应体系中的终浓度范围为10μM~0.1nM。测试所用的ATP溶液(生工生物工程(上海)股份有限公司,A600311)的浓度为预先测定的对应每个FGFR亚型的ATP Km值浓度,FGFR1~4对应的ATP Km值浓度分别为100μM,40μM,40μM和120μM。反应在384孔微孔板中进行,首先向孔中加入化合物和一定量的FGFR蛋白,并在室温下孵育5-30分钟,随后向反应液中加入ATP溶液和生物素化的多肽底物溶液,并在室温下振荡孵育50分钟。随后向反应中加入偶联有铕系元素化合物的抗磷酸化酪氨酸抗体和偶联有修饰化的别藻蓝蛋白XL665的链酶亲和素,并在室温下继续振荡孵育1小时。孵育结束后,在酶标仪以TF-FRET模式上测定各孔在激发波长为304nm,发射波长为620nM和665nM的荧光强度值。通过与对照组(0.1%DMSO)的荧光强度比值进行比较计算化合物在各浓度下的百分比抑制率,并通过GraphPad Prism 5软件以化合物浓度对数值-抑制率进行非线性回归分析,或得化合物的IC50值,见表1。

测试例2、本发明化合物对肝癌细胞Huh7活性测定

实验方法按照试剂盒说明书的步骤操作,简述如下:受试化合物首先溶解于DMSO中制备为贮存液,随后以对应细胞的培养基进行梯度稀释,配制成测试样品,化合物的终浓度范围在30μM-0.01nM。将处于对数生长期的肿瘤细胞以适宜的密度接种至96孔细胞培养板中,在37℃,5%CO2培养箱内过夜后,加入测试化合物样品后继续培养细胞72小时。培养结束后,向每孔加入适宜体积的CCK-8检测液,并在37℃下孵育1~4小时,随后在酶标仪上读取样品各孔在450nM下的吸光度数值。通过与对照组(0.3%DMSO)的吸光度数值进行比较计算化合物在各浓度点的百分比抑制率,之后在GraphPad Prism 5软件中以化合物浓度对数-抑制率进行非线性回归分析,得到化合物抑制细胞增殖的IC50值,见表2。
