Abstract
本发明公开一种EGFR蛋白酪氨酸激酶的临床突变体的选择性抑制剂,及具有如式(I)的结构,是一类含有三嗪的双芳香环模板化合物,同时公开了该类化合物的制备方法和其作为EGFR蛋白酪氨酸激酶的临床突变体的选择性抑制剂的应用,尤其是对于T790M变异的表皮生长因子受体EGFR的抑制作用,和在治疗与表皮生长因子受体EGFR过度表达相关疾病如肾癌、肺癌、前列腺癌、胰腺癌、乳腺癌和胶质细胞瘤。
Description
技术领域
本发明涉及三嗪双芳香环衍生物。
背景技术
皮生长因子EGFR(epithelial growth factor receptor)是一个170kDa的跨膜糖蛋白受体酪氨酸激酶,由表皮生长因子激活,影响细胞的生长和分化。EGF或TGFα对EGFR的结合激活受体的酪氨酸激酶活力。EGFR羧基末端的酪氨酸残基Tyr1068、Tyr1148、和Tyr1173是EGF结合后发生的自动磷酸化的主要位点。一旦被激活,EGFR1068位和1173位磷酸化的酪氨酸残基就能介导Grb2对EGFR的结合。此外,1173位磷酸化的酪氨酸残基是SHC在EGFR上的主要结合位点。EGFR广泛分布在许多正常和恶性上皮细胞中,其过度表达和自我激活可能与许多肿瘤的发生发展有关。目前主要用于各种上皮源性恶性肿瘤包括头颈部鳞癌、肺癌、乳腺癌和膀胱癌等的研究。
蛋白酪氨酸激酶(protein tyrosine kinase,PTK)是一类催化ATP上γ-磷酸转移到蛋白酪氨酸残基上的激酶。许我生长因子受体蛋白包括表皮生长因子受体通过磷酸化而起作用,表皮生长因子受体EGFR酪氨酸激酶使表皮生长因子受体磷酸化。临床上,EGFR酪氨酸激酶抑制剂已被用于癌症的治疗,第一代可逆的EGFR酪氨酸激酶抑制剂吉非替尼和埃罗替尼。对身体里有这些特定的激活突变的病毒人表现出了显著的临床反应(50-80%)。然而,对于这些药物产生继发性而药突变的病人会几个月内遭受癌症的复发。第二代EGFR酪氨酸激酶抑制剂包括来那替尼,达克替尼,阿法替尼,这些药物的结构中都含有亲电的基团Michael受体。其中以阿法替尼为药物代表为例,烯丙酰胺结构对阿法替尼的抗肿瘤活性起着至关重要的作用,它作为Michael受体与EGFR上半胱氨酸残基(Cys797)的催化部位(新核的巯基)发生迈克尔加成反应,从而使激酶失活,不可逆地抑制酪氨酸激酶的活性,因而具有良好的耐受性。研究者们通过培养抑制剂与受体的晶体,从分子水平上完全证明了这些共价键的存在,并且发现了阿法替尼通过与HER2的Cys 805以及HER4的Cys 803作用进而强力抑制这些酶。在对野生型EGFR体外测试显示,阿法替尼在对野生型EGFR与L858R/T790M双突变型的抑制作用与吉非替尼、埃罗替尼以及拉帕替尼相比有着更好的效果。此外,阿法替尼对DER4的抑制作用高于拉帕替尼30倍。第三代EGFR酪氨酸激酶抑制剂奥希替尼对L858R/T790M/C797S三突变型的抑制作用也达到纳摩尔。以奥希替尼为先导,进一步开发出对突变型具有强抑制作用的EGFR酪氨酸激酶抑制剂,同时,研发高效、低毒的具有耐药性的抗肿瘤新药在当前药物研发领域中十分重要。

实施例9:EGFR激酶抑制活性及相关突变位点结合率的测定
对上述实施例1-8制得的化合物601-608,采用FRET技术来测定前述化合物对EGFR激酶抑制活性,该抑制活性采用IC50这一指标对表示,IC50即EGFR激酶的活性被抑制50%时的化合物的浓度。
同时采用TR-FRET技术对本发明化合物实施例1-8制得的化合物601-608的EGFR-T790M激酶活性抑制作用进行测定,也采用IC50这一指标对表示。采用Life technologies公司Z’-LYTETM Kinase Assay Kits(PV3193),并选用Tyrosine 4Peptide中的EGFR-T790M激酶解决方案进行活性测定试验。测定结果见表2
表2实施例化合物的EGFR抑制活性及EGFRT790M结合率测定
实施例10:本发明化合对癌细胞株的抑制活性测定(MTT法检测)
细胞株:人非小细胞肺癌腺癌细胞株NCI-H1975(EGFR-T790M高表达),人非小细胞肺细胞株A549(EFGR高表达)。
方法:将细胞株NCI-H1975和A549置于20%FBS(胎牛血清)(Gibco)+1640+1%双抗进行培养。然后取生长状态良好的NCI-H1975细胞,5000个/孔分别接种于96孔细胞板,置于37℃、含5%CO2的培养箱中孵出育24h使细胞贴壁完全。弃去旧培养液,每孔依次加入100μL含0.3、1、3、10、30、100、300、1000、3000和10000nmol/L待测化合物的培养液,溶剂对照组每孔加入100μL含0.1%DMSO的培养液,每组3复孔,72h后弃去旧的培养液,避光条件下每孔加入100μL含0.5mg·mL-1MTT的培养液,置于细胞培养箱中继续孵育4h,弃去上清,每孔加入100μLDMSO,振荡,用酶标仪在492nm波长下测定各孔吸光度值。根据各化合物不同浓度对备细胞生长的抑制率,经换算得到下表中的IC50(nM)。
