Description

FGFR4抑制剂的盐型、晶型及其用途 技术领域
本发明涉及N-((3S,4S)-3-((6-(2,6-二氯-3,5-二甲氧基苯基)-9-甲基-5,6-二氢嘧啶并[5,4-c][1,8]萘啶-2-基)氨基)四氢-2H-吡喃-4-基)丙烯酰胺的新晶型、盐型及所述盐型的结晶形式。本发明还涉及包含所述晶型或盐型的药物组合物，所述盐型、晶型和药物组合物作为FGFR4抑制剂的用途，以及治疗FGFR4介导的疾病的方法。
背景技术
成纤维细胞生长因子受体(FGFR)属于受体型酪氨酸蛋白激酶(Receptor Tyrosine Kinase，RTK)超家族的一员，FGFR通过与成纤维细胞生长因子(fibroblast growth factor,FGF)结合，在不同组织中经过复杂的信号传递路径对细胞的增殖、分化和迁移进行调节(Jouanneau J et al.Oncogene,1999,18:327-333)。FGFR为单链糖蛋白，由胞外区、单次跨膜区及细胞质内的酪氨酸激酶区组成，其中胞外区由前导肽和3个免疫球蛋白结构域构成。FGFR酪氨酸激酶家族包括FGFR1、FGFR2、FGFR3和FGFR4。其中FGFR4基因位于染色体5q35.1上，其长度约为11.3kb，有18个外显子(Kostrzewa M.Mammalian genome,1998,9(2):131-135)。FGFR4蛋白属于FGFR酪氨酸激酶家族的重要成员，其第388位氨基酸位于RTK结构高度保守的跨膜区内，此结构改变所导致的FGFR4蛋白病理生理功能变化，可增强酪氨酸激酶的活性。FGFR4蛋白是一类具有自身磷酸化活性的跨膜酪氨酸激酶受体，在胚胎发育、组织修复和血管生成等进程中起着重要的作用(Eswarakumar V P et al.Cytokine Growth Factor Rev,2005,16(2):139-149)。
FGFR4的信号通路：当配体由肝素或类肝素介导后便与FGFR4结合，致使FGFR4单体发生二聚化，随着细胞质内C末端、激酶插入区及近膜区的酪氨酸磷酸化后，A环(activation loop,A loop)激酶区经磷酸化使得FGFR4活化(Schlessinger J et al.Mol Cell,2000,6:743-750)。活化后的FGFR4主要有两个 胞内作用物：磷脂酶C和FGF受体底物2(FRS2)(Dailey L et al.Cytokine Growth Factor Rev,2005,16:233-247)。
FGFR4活化后，磷脂酶C的Src同源区2(SH2)结构域便与其活化的C末端酪氨酸结合，使PLC磷酸化后结合在C末端酪氨酸位点上。激活的PLC水解其底物4,5-二磷酸磷脂酰肌醇(PIP 2)形成二酰基甘油(DAG)和三磷酸肌醇(IP 3)。IP3与细胞内特异受体结合来刺激细胞内的钙池释放Ca 2+，Ca 2+与钙调蛋白结合以激活Ca 2+/钙调蛋白依赖性蛋白激酶。另外，Ca 2+与二酰基甘油都能激活蛋白激酶C家族中的成员。PIP2水解产生的二级信号除了能激活转录因子外，还能激活多种细胞内的反应。
SOS蛋白与生长因子受体结合蛋白2(growth factor receptor bound 2,Grb2)的Src同源区3(SH3)结构域结合形成Grb2/SOS复合物，该复合物可与FGFR4相连或与FGF受体底物2α(FGFR substrate 2α，FRS2α)结合，其中FRS2α与跨膜蛋白-磷酸酪氨酸结合域(phosphotyrosine binding domain,PTB)相连，促进鸟嘌呤核苷在Ras上面交换使Ras成为Ras-GTP，从而启动下游MAPK信号通路。
FGFR4的自身磷酸化使JAK家族因子(JAK)活化，活化的JAK使FGFR4上的特异性信号蛋白吸附位点磷酸化，此位点可以充当信号传导及转录激活蛋白(signal transducer and activator of transcription,STAT)及其他信号分子的停泊位点。STAT蛋白被FGFR4的停泊位点吸附后，其C端的酪氨酸残基被JAK磷酸化，随后便脱离受体形成稳定的同源或异源二聚体并转移到细胞核中与γ干扰素活化部位(gammainterferon activation site,GAS)增强子家族成员结合，激活靶基因的转录。
小分子FGFR4抑制剂是通过阻断胞外配体分子与受体的结合或胞内激酶信号的传递，以抑制FGFR4所介导的增殖信号。目前在开发的靶向FGFR4抑制剂有多种，阿斯利康研发了FGFR4选择性抑制剂AZ709，其体外实验对高水平表达FGF19或FGFR4的细胞显示出很好的抑制效果，但体内实验无明显作用。诺华公司的FGFR4选择性抑制剂FGF401能特异性靶向FGFR4，治疗其过表达的肝癌等恶性肿瘤。H3生物医药公司的FGFR4特异性抑制剂H3B6527对FGF19基因扩增的细胞具有强抗肿瘤活性，且在小鼠和猴的动物模型中没有胆汁酸相关 的不良反应。蓝图医药研发并报道了一个FGFR4特异性的抑制剂BLU554以治疗FGFR4过表达的肝癌和胆管癌。
随着科研人员对FGFR4结构和功能关系的深入了解以及其与其它基因相互作用的深入研究，特应性强、治疗效果好且不良反应低的FGFR4将会被设计开发出来，采用FGFR4分子靶向治疗肿瘤将非常有意义。
鉴于活性成分的化学稳定性、固态稳定性和存储周期等性能对于药物来说都是非常重要的因素，因此探索可药用化合物的新盐型、新晶型或多晶型物提供了提高医药产品的整体性能的机会，同时扩大了制剂科学家设计时可用的材料品种。特定有机药物化合物的盐型和/或多晶型物，由于各自的独特的结构，而具有明显不同的物理性质，如形貌、熔点、溶解性、吸湿性及稳定性等，进而在药物制剂配制、治疗活性和化学、物理稳定性方面呈现出不同的行为。虽然技术人员有动机进行特定有机药物化合物的盐型和/或晶型的探究，但是应该注意到，通常无法单从分子结构预知化合物将发生何种成盐或结晶行为，无法预测特定有机药物化合物存在多少种晶体形式以及存在何种晶体形式，更不可能预测晶型本身的结构和性质。

使用体外细胞试验评估本发明的化合物对人肝癌细胞Hep3B细胞增殖的影响。试验中所用的检测方法是CELL TITER-GLO(CTG)发光法，该法可通过对ATP进行定量测定来检测活细胞数目。因为ATP参与生物体内多种酶促反应，是活细胞新陈代谢的一个指标，其含量直接反应了细胞的数量及细胞状态，实验过程中向细胞培养基加入CellTiter-Glo TM试剂，测量发光值，发光值与ATP量成正比，而ATP又和活细胞数正相关，因此可通过检测ATP含量考察细胞活力。

BALB/c nu/nu雌性小鼠右前肩胛处皮下接种5×10 6个人肝癌细胞Hep3B，细胞悬浮液与基质胶体积比为1:1(0.2/mL/只)。待肿瘤平均体积为158mm 3时，根据肿瘤大小随机分组，治疗组给予用适当的溶剂制备的待测化合物溶液，溶剂对照组给予空白溶剂。治疗过程中，每周测量两次肿瘤体积、末次给药后测定肿瘤重量以确定化合物活性。通过比较治疗组和溶剂对照组的肿瘤体积和重量，计算肿瘤增长抑制率(％，TGI)。体重测量作为毒性的常规测定，与肿瘤体积测量频率相同。在该模型中，本发明结构式I所示化合物显示出很好的抗肿瘤活性。例如，当剂量为50mg/kg、100mg/kg和200mg/kg(BID×14)时，结构式I所示化合物对Hep3B肿瘤体积增长抑制率分别为73.02％、86.26％和90.26％，对HepB肿瘤重量增长抑制率分别为84.76％、92.27％和98.15％，显示结构式I所示化合物在抑制肿瘤体积和重量方面均表现出剂量依赖效应。此外，整个实验过程中，给予结构式I所示化合物的动物均未出现明显的体重降低，提示两种化合物在受试剂量条件下耐受良好。
