Description

EGFR激酶抑制剂及其制备方法和应用 技术领域
本发明涉及药物化学领域,具体地,本发明提供了一种EGFR激酶抑制剂,及其制备方法和应用。
背景技术
EGFR(epidermal growth factor receptor,简称为EGFR、HER1或ErbB-1)是表皮生长因子受体(HER)家族成员之一,该家族成员在细胞生理过程中占据重要位置。EGFR属于酪氨酸激酶型受体,该信号通路在细胞增殖,生长,分化等过程中起重要调节作用,其异常过表达或突变通常会引发肿瘤。
小分子酪氨酸激酶抑制剂通过对EGFR胞内区酪氨酸激酶磷酸化位点的竞争性结合,阻止了ATP与受体激酶的相互作用,阻断由配体-受体结合所诱导的胞内区激酶的自磷酸化,并阻断由EGFR受体二聚所引发的交叉磷酸化,进而阻断下游信号通路,具有高效性和特异性。
使用第一代可逆结合酪氨酸激酶抑制剂如吉非替尼(Gefitinib)和埃罗替尼(Erlotinib)时易发生获得性耐药,Michael J.Eck等发现这种耐药主要是由于ErbB1的gatekeeper残基发生T790M突变引起,该突变通过增强ATP和EGFR酪氨酸激酶的亲和力从而产生耐药性。
Wenjun Zhou等于2009年发现了WZ4002,WZ8040等新型的突变选择性小分子抑制剂:

Emily J.Hanan等通过环合策略获得了新的激酶抑制剂:
Figure PCTCN2016089679-appb-000002
Kwangho Lee等也在此基础上发展了一系列EGFR激酶抑制剂(US2012157426),发现I-1具有很好的抑制活性:
Figure PCTCN2016089679-appb-000003
他们进一步设计了化合物I-4(KR20130133202,CN103269704):
Figure PCTCN2016089679-appb-000004

活性测试实施例
测试实施例1化合物对6株肿瘤细胞增殖的影响
实验方法:
体外培养人肺癌细胞H1975、H522,人肝癌细胞HepG2,人黑色素瘤细胞A375和人表皮癌细胞A431,人结肠癌细胞COLO205,细胞生长至对数生长期后,收集细胞,1000rpm离心5min,弃上清,适量培养基悬浮,调整细胞浓度至2.5~5.5×104/ml(有一次是3.0~5.5×104/ml)。将细胞悬液接种到96孔细胞培养板中,每孔100μl,放置细胞培养箱(37℃,5%CO2)中培养24h后,用药组每孔加入细胞培养基稀释的药物100μl,每种药物设三个复孔,阴性对照组为含0.5%DMSO培养基。培养箱中培养72h后,每孔加入5mg/ml的MTT 20μl,置37℃放置3h。每孔加入150μlDMSO,于37℃摇床振荡5min,于492nm检测吸光度(OD)。运用Prism Graphpad统计软件计算IC50值。
各化合物的编号和结构如下,其中,1686为对照化合物。

Figure PCTCN2016089679-appb-000069
Figure PCTCN2016089679-appb-000070
从上述测试结果中可以看出,本发明的化合物对于肿瘤细胞均具有较低的抑制浓度。其中,与本领域中通常所知的电子等排体理论具有差异的是,与对照化合物1686相比,结构中仅相差一个氮原子的ES071(前者结构中为苯环,后者为吡啶环,两者在电子等排体理论中,属于常见的电子等排体)的活性具有显著的提升,对于大部分的肿瘤细胞抑制浓度仅为前者的1/2。这说明本发明的化合物在现有技术的基础上,取得了预期 之外的优异技术效果。

表2.药物配制表
Figure PCTCN2016089679-appb-000072
药物配置后均为混悬液,放置后有析出。
3.实验步骤
在无菌条件下,取处于生长增殖期的H1975细胞,消化后调整细胞浓度,接种于裸鼠腋窝下,每只接种体积为0.1mL。用游标卡尺测量移植瘤直径,待肿瘤生长至约400mm3时选 取荷瘤鼠30只,根据肿瘤大小随机分成5组。各组按设定实验方案给药,给药当天记为D1,阴性对照组给予等量溶媒,以后每周测量2次肿瘤长径和短径,同时称量小鼠体重。
疗效评价指标:
于首次给药当天开始观察、测量并记录相关指标,实验中用游标卡尺测量肿瘤尺寸以观察瘤块体积变化和生长速度。实验终点时处死荷瘤小鼠,并解剖分离瘤块称重。
疗效评价指标包括:相对肿瘤增殖率及体重、一般状态等相关毒性指标。实验结束时绘制各组肿瘤生长曲线和体重变化曲线。
肿瘤体积(tumor volume,TV)的计算公式为:TV=1/2×a×b2,其中a、b分别表示肿瘤长径和短径。根据测量的结果计算出相对肿瘤体积(relative tumor volume,RTV),计算公式为:RTV=Vt/V0。其中V0为给药前测量的肿瘤体积,Vt为给药后每一次测量时的肿瘤体积。
抗肿瘤活性的评价指标为相对肿瘤增殖率T/C(%),计算公式如下:T/C(%)=(TRTV/CRTV)×100%,TRTV:治疗组RTV;CRTV:阴性对照组RTV,T/C(%)≤40%,并经统计学处理P<0.05为有效。或者瘤重(tumor weight,TW)低于阴性对照组,并经统计学处理P<0.05为有效。肿瘤的抑制率IR(%)=(1-TTW/CTW)×100%,TTW:治疗组TW;CTW:阴性对照组TW。
统计方法:
数据以Mean±SD表示,组间比较应用t检验。
4.试验结果
4.1药物对动物体重的影响
从各处理组动物体重变化趋势分析,本发明化合物和阳性药物CO-1686组动物与阴性对照组相比体重无显著性差异(图1),说明本发明的化合物具有较好的安全性。连续灌胃给药14天后,动物进行安乐死,解剖尸检,大体观察各脏器未发现异常。
4.2药物对动物荷瘤大小的影响
连续灌胃给药14天,ES系列化合物和阳性药物组动物皮下肿瘤体积均小于阴性对照组,与阴性对照组相比,均有显著性差异(见图2、图3、图4),说明药物有效,而且ES-072的抑瘤效果要优于阳性对照药CO-1686组。
试验终点,即给药第14天,动物行安乐死,解剖皮下肿瘤并称重。ES系列化合物和阳性药物肿瘤显著小于阴性对照组,瘤重见图5,肿瘤照片见图6。CO-1686抑瘤率为50.09%,ES-071、ES-072、ES-075抑瘤率分别为50.93%、79.42%和37.27%。其中,ES-072化合物(体外抑瘤活性稍逊于ES-071)在体内抑瘤实验中令人意外地表现出了大大优于对照化合物的抑瘤活性,这表明该化合物在给药后具有优于对照化合物的生物利用度,是一种极具开发前景的化合物。
