Description

苯并呋喃吡唑胺类蛋白激酶抑制剂 技术领域
本发明涉及调节蛋白激酶活性、且用于预防和治疗与蛋白激酶相关疾病的化合物。具体而言,本发明涉及一种苯并呋喃吡唑胺类蛋白激酶抑制剂,属于调节间变性淋巴瘤激酶(ALK)活性的化合物,并提供了该类化合物的制备方法,及该类化合物用于预防或治疗与ALK相关的疾病的制药用途。
背景技术
恶性肿瘤是一种严重威胁人类健康的常见病和多发病,其特点是细胞或变异细胞异常增殖。肿瘤细胞的增殖、凋亡、转移等与细胞内外的一系列信号传导通路中某个环节出现异常密切相关。在这些信号传导途径中,一类重要的分子就是蛋白激酶,蛋白激酶的异常与肿瘤的发生、发展及预后转归密切相关,也是导致一系列其它与炎症或增殖反应有关的人类疾病的主要原因;开发靶向蛋白激酶的药物是治疗相关疾病的主要手段,已有很多药物获批上市,这类药物具有靶点清晰、疗效明确、安全性高的特点,因此越来越受到临床医疗实践的认可和支持。
间变性淋巴瘤激酶(ALK)是蛋白激酶家族的重要成员,现有研究表明ALK的过度表达、突变和融合蛋白与多种肿瘤直接相关,包括但不限于成神经细胞瘤、间变性大细胞淋巴瘤(ALCL)、非小细胞肺癌(NSCLC)和炎性肌纤维母细胞瘤(IMT)等等。针对ALK融合基因的第一代药物克唑替尼(Crizotinib)及第二代药物色瑞替尼(Ceritinib)已分别于2011年和2014年上市,用于ALK阳性肺癌患者的治疗获得显著的无进展生存和客观有效率,证实了该靶点明确的临床价值。尽管药效显著,由于肿瘤异质性特点及肿瘤细胞对环境压力的适应,有越来越多的研究报道表明,肿瘤耐药、疾病继续发展几乎依旧是此类患者必然的命运;此外,现有药物的严重不良反应,如消化道不良反应发生率过高、肝脏毒性及QT间期延长等问题,也限制了该类药物的应用。
如,Luc Friboulet、Nanxin Li、Ryohei Katayama、Jeffrey A Engelman等人发现:第一代ALK抑制剂Crizotininb治疗后,在一年左右大多出现耐药,主要出现L1196M、G1269A、S1206Y和I1171T位点突变,其中L1196M是门控位点;第二代 ALK抑制剂Ceritinib能解决第一代ALK耐药的问题,但是ceritinib对G1202R、C1156Y、1151T-ins、L1152R和F1174C突变位点也出现了耐药现象(The ALK Inhibitor Ceritinib Overcomes Crizotinib Resistance in Non-Small Cell Lung Cancer;Cancer Discov;2014年4月;4(6):662-673.)。
有鉴于此,继续研制具有良好ALK抑制活性及安全性的新化合物并将其开发上市以应对上述问题具有重要的社会效益和价值。

实施例32斑马鱼表型筛选实验
斑马鱼是一种脊椎动物,与人类基因同源性高达85%,其信号传导通路与人类基本近似,生物结构和生理功能与哺乳动物高度相似;其体积小、发育迅速、胚胎透明、产卵量高,这些独特优势使得斑马鱼成为人类疾病研究和活体高通量药物筛选的最佳模式生物体之一。其中,间变性淋巴瘤激酶ALK(Anaplastic lymphoma kinase)在人类与斑马鱼中基因同源性达76%。斑马鱼的白细胞酪氨酸激酶ltk(leukocyte tyrosine kinase)调控斑马鱼虹膜色素细胞的生成(Lopes,S.S.,Yang,X.,et al.(2008).Leukocyte tyrosine kinase functions in pigment cell development.PLoS Genet,4.),虹膜色素细胞在斑马鱼中表现为一种银色小体,分布在头部、眼睛、脊柱外侧(反射光观察),利用黑色素缺失的Albino斑马鱼,在透色光中可以观察到银色小体为黑色,见说明书附图的图1。ALK与LTK是sister kinase,研究者发现注射外源性的ALK质粒同样可以调节虹膜色素细胞的生成,实验结果也表明ALK抑制剂大多有LTK活性,可以抑制虹膜色素细胞的生成(Rodrigues,F.S.,Yang,X.,Nikaido,M.,Liu,Q.,&Kelsh,R.N.(2012).A simple,highly visual in vivo screen for anaplastic lymphoma kinase inhibitors.ACS Chem Biol,7,1968-1974.)。
因此,利用这一原理,我们考察化合物对正常斑马鱼虹膜色素细胞的影响,来探讨化合物在体内抗ALK活性的强弱。
实验(一)化合物对正常斑马鱼虹膜色素细胞的影响
方案:选取6hpf(hours post fertilization)的鱼卵,随机分组,然后加入各浓度的受试药物,至3dpf(days post fertilization)时进行图象采集,然后利用ImageJ软件分析泄殖孔至尾鳍部位斑马鱼脊背侧虹膜色素细胞的IOD(integrated option density)值,采用Graphpad prism6.0进行Dunnett’s T-检验进行统计学分析,p<0.05表明具有统计 学差异,虹膜色素抑制率计算公式如下:

本发明的化合物REX-D2对斑马鱼虹膜色素细胞影响的量效关系图,见图2;化合物REX-D2对斑马鱼虹膜色素细胞的影响图,见图3;从图中明显可见,化合物REX-D2在不同的浓度剂量下,都有显著的抑制虹膜色素细胞形成的作用,表明本化合物在体内的抗ALK活性显著。
实施例33在人肺癌NCI-H2228皮下移植模型中的药效学试验
(1)实验方法
Balb/c nude小鼠皮下接种NCI-H2228细胞,建立皮下肿瘤模型。试验分为阴性对照组、测试药ceritinib组(对照药)、测试药REX-D2组;测试药组各组给药剂量均为30mg/kg;每组8只小鼠,各组均连续口服灌胃给药,每天给药一次,共给药14天,然后停药观察两周。根据动物体重变化和死亡情况进行安全性评价。
(2)评价指标
肿瘤体积(Tumor volume,TV)的计算公式为:TV=a×b2/2。其中a、b分别代表肿瘤测量长和宽。
相对肿瘤体积(relative tumor volume,RTV)计算公式为:RTV=Vt/V0。其中V0为分组给药时的肿瘤体积,Vt为测量时的肿瘤体积。
抗肿瘤活性的评价指标为相对肿瘤增殖率T/C(%)和抑瘤率TGI(%),计算公式分别为:T/C(%)=(TRTV/CRTV)×100%。TRTV为治疗组RTV,CRTV为阴 性对照组RTV;抑瘤率TGI(%)=(1-T/C)×100%。
(3)实验结果:见图4
给药后14天(即给药结束后第一天)时,阴性对照组小鼠平均肿瘤体积为350mm3。测试药ceritinib、REX-D2在30mg/kg的剂量条件下均产生了显著的抗肿瘤作用(p值分别为p=0.001、p<0.001),平均肿瘤体积分别为17mm3、13mm3,较给药开始时均为肿瘤明显缩小或被治愈,各治疗组相对肿瘤抑制率TGI分别为:ceritinib治疗组94.7%、REX-D2治疗组96.1%。
至实验终点(即给药结束后第15天)时,阴性对照组小鼠平均肿瘤体积为515mm3,治疗组小鼠肿瘤均无肿瘤生长,并且有缩小趋势。各治疗组相对肿瘤抑制率TGI分别为:ceritinib治疗组95.3%、REX-D2治疗组98.8%。
结论:在30mg/kg的剂量,每天给药一次,连续给药14天的条件下,测试药ceritinib,REX-D2对NCI-H2228人肺癌皮下移植模型均产生了显著的抗肿瘤效果;各受试药物在本实验所设定条件下小鼠均可以耐受。
