Description

一种靶向EGFR突变的吡咯并[2,3-d]嘧啶衍生物及其制备方法和用途 技术领域
本发明属于化学医药领域,具体涉及一种靶向EGFR突变的吡咯并[2,3-d]嘧啶衍生物及其制备方法和用途。
背景技术
肺癌是全球范围内发病率和死亡率最高的恶性肿瘤,每年因肺癌造成的死亡人数达到160万,是导致男性(22%的癌症死亡)和女性(13.8%的癌症死亡)癌症相关死亡的主要原因。在美国,大约14%的新发癌症是肺癌。美国癌症协会(American Cancer Society)估计,2018美国的肺癌病例约为23.4万,死亡病例约为15.4万。我国的情况同样严重,根据2019年1月国家癌症中心发布的中国最新癌症数据显示,肺癌是我国发病率和死亡率第一的恶性肿瘤,对国民健康造成极大的威胁,给社会经济发展带来极大压力。非小细胞肺癌约占所有肺癌的85%,这些患者具有同一组织学亚型。非小细胞肺癌又包括肺腺癌(LUAD)、肺鳞癌(LUSC)和大细胞癌。
在过去的20年中,肺癌的治疗取得了很多进展,包括针对肺腺癌特定分子亚型的方法以及治疗肺鳞癌的新方法的发展。目前肺癌的药物治疗手段主要包括化疗、免疫治疗以及分子靶向治疗。
EGFR是酪氨酸激酶I型受体家族成员,其基因位于人类7号染色体上。EGFR中有28个外显子,它们可以形成一种分布在各种上皮细胞细胞膜上的蛋白质,与表皮生长因子或EGF结合,调节细胞的生长。相比之下,在非小细胞肺癌EGFR突变中,20外显子插入和18点外显子突变要比19外显子缺失和21L858R外显子替换少见。EGFR及其下游基因的激活和调控导致细胞增殖、凋亡和血管生成。一些针对EGFR突变的药物已经被开发出来,如酪氨酸激酶抑制剂(TKIs),BRAF抑制剂。
20世纪90年代末,随着口服EGFR酪氨酸激酶抑制剂(TKI)吉非替尼的问世,NSCLC患者的分子靶向治疗首次得到应用。埃罗替尼是另一种针对EGFR的TKI,对于晚期非小细胞肺癌患者,这种药物比维持疗法生存率更高。研究表明,绝大多数受益于EGFR TKIs的患者身上都观察到了EGFR突变的激活。包括ALK重排、ROS1融合和BRAF突变在内的额外基因改变有效地促进了靶向治疗的发展。
在过去的几十年里,酪氨酸激酶抑制剂一直被认为是治疗非小细胞肺癌的有效药物,也是很好的靶向药物。针对EGFR出现了多种药物,如吉非替 尼、埃罗替尼、西妥昔单抗和帕尼单抗。一些研究表明,与一线化疗相比,两种第一代EGFR TKIs(吉非替尼和埃罗替尼)在PFS方面具有实质性的好处。但是,晚期NSCLC患者化疗后,EGFR-TKI对OS的影响不明显。一些研究表明,患者在接受第一代EGFR-TKI治疗10-14个月后出现耐药性。第一代EGFR-TKI在NSCLC中的耐药机制已被鉴定为TK结构域突变(T790M)、MET扩增、RAS突变等。TK区域突变(T790M)被认为是NSCLC患者最常见的获得性耐药突变。有T790M突变的NSCLC患者中有一部分从未接受过EGFR-TKI治疗。这些发现提示T790M突变是NSCLC患者的潜在靶点。因此,需要开发新的措施和疗法来克服耐药性。
近年来,奥西替尼作为第三代EGFR-TKIs出现,它能够靶向敏感和耐药的EGFR突变(T790M)。在FLAURA研究中,奥西替尼治疗的NSCLC患者的中位PFS(18.9个月)明显长于第一代EGFR-TKIs(吉非替尼和埃罗替尼)患者的中位PFS(10.2个月)。然而不幸的是,一项研究表明,奥西替尼的耐药性已经出现。在45例患者身上出现了EGFR C797S突变,PIK3CA、KRAS、BRAF突变以及MET扩增。在EGFR突变的NSCLC中,5-20%EGFR-TKI药物耐受患者出现MET扩增。MET扩增增加了NSCLC中HCC827细胞的增殖和迁移。所以,仍然需要不断研发更新的第三代EGFR-TKI靶向药物分子。

2、试验结果
2.1 CCK8法检测本发明化合物对不同肺癌细胞系的增殖抑制作用
本发明9个目标化合物选择不同浓度(0、3.125、6.25、12.5、25、50μmol)用CCK8法测试对不同肺癌细胞的增殖抑制,以市售艾维替尼作为阳性对照物,对不同肺癌细胞活性进行评价,选择肺部正常细胞系和不同的肺癌细胞系进行实验,48h实验结果如表6和图12所示,从这一些化合物中筛选出抗癌细胞活性高的化合物,进一步研究化合物的抗肿瘤活性。
表6.本发明化合物对正常细胞和不同肺癌细胞系的抑制活性(IC 50/μM)
Figure PCTCN2020127884-appb-000022
从实验结果可以看出,除了化合物9以外,其它化合物均具有一定的体外肿瘤细胞系的增殖抑制活性。
(1)与阳性对照市售艾维替尼相比,化合物1(实验室合成的艾维替尼)对人正常支气管上皮样细胞BEAS-2B细胞和HBE细胞的抑制活性,以及对不同的肺癌细胞(人大细胞肺癌细胞H460细胞,人肺腺癌细胞A549细胞,EGFR突变型细胞H1975细胞和HCC827细胞)的抑制活性和阳性对照基本保持一致。
(2)与化合物1相比,化合物2对人正常支气管上皮样细胞BEAS-2B细胞和HBE细胞的抑制活性,以及对不同的肺癌细胞(人大细胞肺癌细胞H460细胞,人肺腺癌细胞A549细胞,EGFR突变型细胞H1975细胞和HCC827细胞)的抑制活性和阳性对照基本保持一致。
(3)与化合物1相比,化合物3对人正常支气管上皮样细胞BEAS-2B细胞和HBE细胞的抑制活性,以及对不同的肺癌细胞(人大细胞肺癌细胞H460细胞,人肺腺癌细胞A549细胞和EGFR突变型细胞H1975细胞)的抑制活性,均更低,但对HCC827细胞的抑制活性则与化合物1相近,表现出化合物3对HCC827细胞的良好选择性。
(4)化合物4对不同细胞系的抑制效果与化合物3相似。
(5)化合物5对不同细胞系的抑制效果与化合物2相似。
(6)化合物6对不同细胞系的抑制效果与化合物3相似。
(7)化合物7对不同细胞系的抑制效果与化合物2相似。
(8)化合物8对HCC827细胞具有一定的抑制效果,对其它细胞系抑制效果相对较差。
(9)化合物9对不同的细胞系抑制效果相对其它几个化合物均较差。
综上,对不同的细胞系,化合物2,5,7表现出与艾维替尼相近的抑制效果,而化合物3、4、6则对EGFR突变型细胞HCC827细胞具有很强的靶向选择性。特别是:和阳性对照市售艾维替尼相比,化合物6对正常上皮细胞HBE细胞毒性小,选择系数超过490倍(对比HBE细胞和HCC827细胞的IC 50)。
2.2化合物对EGFR磷酸化的抑制
免疫印迹分析证实本发明化合物5和6在H1975细胞中有效抑制EGFR-Tyr992磷酸化。除了抑制EGFR-Tyr992的磷酸化,这两个化合物还抑制了H1975细胞中参与癌细胞增殖和存活的下游两个重要靶点Akt和ERK1/2的磷酸化(图13和图14)。与EGFR磷酸化数据一致,这两个化合物对野生型EGFR细胞中Akt和ERK1/2磷酸化的抑制作用要弱得多。总的来说,从分子机理来看,EGFR磷酸化检测结果表明新合成的两个化合物对EGFR磷酸化的抑制和艾维替尼(图15)保持了一致,它抑制了EGFR T790M和其他敏感突变。
2.3细胞凋亡测定
由于化合物对肿瘤细胞的良好抑制作用,以化合物5和6为代表,用流式进一步检测了其对细胞凋亡的诱导作用。结果如图16、图17、表7和表8所示。
实验分别选用了人肺癌细胞HCC827细胞和H1975细胞作为检测系统,对照组为空白对照(DMSO),化合物测试浓度为0.5μM和5μM,用化合物处理18h后,采用流式进行检测。在细胞凋亡结果图中,象限E1中的细胞为坏死细胞,象限E2为晚期凋亡细胞,象限E3区域中的细胞代表活细胞,象限E4中的细胞为早期凋亡细胞。从测试结果可以看出,化合物5和6对HCC827和H1975细胞均有一定的凋亡诱导作用。

2.4细胞周期测定
采用PI染法检测细胞周期,确定化合物5和6对HCC827细胞和H1975细胞的阻滞作用,从而进一步证明药物对细胞增殖的抑制。实验结果显示(图18、图19、表9和表10),与对照组相比,化合物处理后的两种细胞在G0/G1期的比例均有明显增高。而相应的S期和G2/M期的细胞比例下降,这表明药物将癌细胞的细胞周期阻滞在G0/G1期。
