Abstract
本发明涉及一类如下通式(I)所示的咪唑并[1,2‑a]吡啶类化合物、其制备方法、包含此类化合物的药物组合物及在制备治疗酪氨酸激酶c‑Met信号转导通路相关的细胞增生疾病的药物中的用途。
Description
技术领域
本发明涉及药物化学和药物治疗学领域,具体涉及作为受体酪氨酸激酶MET抑制剂的咪唑并[1,2-a]吡啶类化合物、其制备方法、含此类化合物的药物组合物及其用途。
背景技术
靶向治疗无疑对癌症治疗产生了重大影响。肿瘤的发生、演化、扩散及肿瘤血管的发生依赖于各种信号转导通路。通过靶向这些信号通路来达到治疗肿瘤的目的已取得了显著进展,并有不少药物已成功上市。例如,基于ABL酪氨酸激酶开发的抗癌药物伊马替尼(imatinib)对慢性髓细胞性白血病(CML)有较好的疗效。近年来,Met原癌基因家族的成员受到了广泛关注。所述Met家族包括Met(也叫作c-Met)和Ron受体。酪氨酸蛋白激酶c-Met是一种细胞表面受体即肝细胞生长因子受体(HGFR),由Met原癌基因编码。与多数其他受体酪氨酸激酶不同,成熟的Met由一条胞外的α链(50kDa)和跨膜的β链(140kDa,将含激酶区的胞内段锚定在细胞膜上)组成异二聚体的结构发挥功能。HGF是Met的配体,作为一个多功能的细胞因子,能够发挥促迁移、抗凋亡以及促有丝分裂的作用。
c-Met在绝大部分的癌及部分肉瘤中具有高表达且和预后差紧密相关,如肺癌、乳腺癌、结肠癌、前列腺癌、胰癌、胃癌、肝癌、卵巢癌、肾癌、神经胶质瘤、黑色素瘤等。c-Met通过与其配体HGF/SF相互作用或者通过其他途径激活胞内段的酪氨酸激酶,诱导细胞增殖、侵袭、迁移,抑制细胞凋亡,促进血管生成,在肿瘤的发生发展过程中发挥重要的作用。
在肿瘤中,c-Met激酶的异常活化机制主要有Met基因扩增、Met基因突变、c-Met转录水平上调、配体依赖性的自分泌和旁分泌环路。Met基因扩增以及随之产生的蛋白过表达和组成型活化存在于众多人类原发癌中,包括胃癌及食管癌、对EGFR抑制剂获得性耐药的非小细胞肺癌及成神经管细胞瘤中。Met基因也可以携带活化性突变。各种Met种系及体细胞突变与肿瘤的发病率相关性较低。在人类肿瘤中最常见的Met组成型活化是非基因扩增的Met转录上调,从而导致蛋白表达增加。另外,HGF自身能够激活Met的转录,并且也可以通过旁分泌的方式正反馈促进癌细胞的分散。HGF也能够以自分泌的形式异常活化Met,多见于胶质细胞瘤、乳腺癌、横纹肌肉瘤以及骨肉瘤。
不同于其他激酶,c-Met可以与细胞表面其他肿瘤相关分子存在相互作用,例如整合素家族、死亡相关受体、其他受体酪氨酸激酶等,从而交联激活放大肿瘤相关效应,极大地促进了肿瘤的发生发展,其中c-Met起到了枢纽的作用,抑制它就可以抑制多个肿瘤靶点发挥的效应。
尤其值得注意的是,临床应用的EGFR受体酪氨酸激酶抑制剂(EGFR-TKIs)获得性耐药正是由于Met基因激活ERBB3信号传导通路而引起的。同时进行的体外试验显示,当阻断c-Met信号后,易瑞沙可以恢复疗效。因此c-Met抑制剂与EGFR抑制剂的联合用药,能够延缓EGFR-TKIs获得性耐药的产生,延长其临床使用寿命,其具有重要的临床意义。
如前所述,阻断HGF-c-Met的信号转导可作为抗肿瘤治疗的策略之一。选择性阻断该通路不仅能够抑制肿瘤生长,还能够抑制肿瘤的转移。目前主要通过3种策略进行针对HGF-c-Met信号通路的靶向c-Met抑制剂研究:HGF与c-Met的生物拮抗剂、抑制PTK催化活性的小分子抑制剂以及针对HGF与c-Met的特异性抗体。其中绝大部分处于临床前研究阶段,少数进入临床研究阶段。例如,Amgen公司研发的注射化人源单抗Rilotumumab已处于临床二期阶段,其适应症包括非小细胞肺癌、大肠癌、前列腺癌、消化道癌等。Pfizer公司研发的PF-02341066小分子抑制剂已处于临床三期阶段。
由于c-Met抑制剂类,尤其是小分子抑制剂类抗肿瘤药物多处于临床研究,尚未进入市场,而抗体药物往往比较昂贵,给该类药物的研发提供了广阔的空间。因此,c-Met激酶是一个富有前景的抗肿瘤药物研究的靶标。

1、实验方法
本实例中采用两种MET依赖肿瘤细胞株:BaF3/TPR-Met细胞(悬浮细胞,无Met胞外段干扰,细胞中TPR-Met融合蛋白表达在胞浆中,能够不依赖于HGF的刺激而持续活化;BaF3本底细胞需外加IL-3才能增殖存活,但导入TPR-Met后,成为Met依赖性敏感细胞株)和EBC-1细胞(贴壁细胞,非小细胞肺癌细胞株,MET基因扩增导致Met持续活化,为Met依赖性细胞株)。
肿瘤细胞的生长抑制检测对贴壁细胞和悬浮细胞分别采用磺酰罗单明B(sulforhodamine B,SRB)和四氮唑盐(microculture tetrozolium,MTT)染色法。具体步骤如下:处于对数生长期的细胞按合适密度(BaF3/TPR-Met,8000/孔;EBC-1,5000/孔)接种至96孔微培养板,每孔100μL,培养过夜后,加入不同浓度(10、1、0.1μM)的化合物作用72h,每个浓度设三复孔,并设相应浓度的生理盐水溶媒对照及无细胞调零孔。作用结束后,贴壁细胞去培养液,加入10%(w/v)三氯乙酸(100μL/孔)于4℃固定1h,随后用蒸馏水冲洗五次,待在室温下干燥后,每孔加入SRB溶液(4mg/mL,溶于1%冰乙酸)100μL,室温下孵育染色15min后,用1%冰乙酸冲洗五次洗去未结合的SRB,室温下干燥后,每孔加入10mM Tris溶液100μL,VERSMax酶标仪测定515nm波长下的光密度(OD值)。悬浮细胞药物处理结束后加入20μLMTT(5mg/mL),37℃培养4h后加入100μL三联液(10%SDS-5%异丁醇-0.01M HCl),37℃过夜,570nm波长下测定OD值。按以下列公式计算药物对肿瘤细胞生长的抑制率:抑制率(%)=(OD对照孔-OD给药孔)/OD对照孔×100%。实验重复两次。
2、实验结果
表1本发明实施例化合物对BaF3/TPR-Met细胞增殖抑制率(%)
表2本发明实施例化合物对EBC-1细胞增殖抑制率(%)
由表可知,该类化合物对肿瘤细胞的抑制水平在纳摩尔等级,其中部分化合物与阳性化合物PF02341066在细胞水平上显示出相当的作用效果。
实施例4:化合物对EBC-1裸小鼠移植瘤的生长抑制作用
1、实验方法
EBC-1按5×106/只分别皮下接种于裸小鼠右侧腋窝,形成移植瘤后再在裸小鼠体内传三代后使用。取生长旺盛期的肿瘤组织,无菌条件下剪切成1.5mm3左右,接种于裸小鼠右侧腋窝皮下。用游标卡尺测定移植瘤直径,当肿瘤体积生长到当肿瘤体积达到100-200mm3时,将动物按瘤体积随机分组,阴性对照组12只,阳性对照组每组6只,实验组每组6只。实验组每日分别口服不同浓度的DC381112(50mg/kg,100mg/kg),阳性对照组每日口服JNJ-38877605(50mg/kg),每日给药一次,连续给药17天,阴性对照组同时给等量生理盐水。
每周两次测量肿瘤长(A)、宽(B),并由此计算肿瘤体积V=A×B2/2。相对肿瘤体积(RTV)的计算遵循:RTV=Vt/V0,Vt为给定时间的肿瘤体积,V0为分笼给药前测量所得肿瘤体积。以相对肿瘤增殖率T/C(%)作为抗肿瘤活性评价指标,T/C(%)=给药组平均RTV/对照组平均RTV×100%。若T/C%≤60%,统计学检测有显著性差异,视为有明显的体内抗肿瘤作用。同时,每周两次称量各组裸鼠体重,以初步评价药物的毒副作用。
2、实验结果
实验结果见图2。
化合物DC38112在50及100mg/kg剂量下对非小细胞肺癌肺癌细胞EBC-1移植瘤模型表现出显著的生长抑制作用,各个剂量组对小鼠体重无明显影响。化合物JNJ-38877605在50mg/kg剂量下对该移植瘤模型表现出非常显著的抑瘤效果,其中4只小鼠的移植瘤消退,化合物对小鼠体重无明显影响。
