技术领域
本发明属于药物化学技术领域,具体涉及一种含苯并噻吩嘧啶衍生物及其制备方法和在制备抗肿瘤药物中的应用。
背景技术
恶性肿瘤是当今世界危及人类生命健康最常见、最严重的疾病。近年来,通过科学家们的不懈努力,已有许多治疗肿瘤的药物上市,这些药物在很大程度上改善了肿瘤病人的生存质量,使肿瘤治疗取得很大的进步。但传统的化疗药物仍存在疗效差、毒副作用强、易产生耐药性等缺陷。因此,寻找或发现高效、低毒、抗耐药的靶向抗肿瘤药物成为目前医学研究的重要课题。蛋白酪氨酸激酶(Protein tyrosine kinases,PTK)是信号传递过程中的重要因子,能催化多种底物蛋白质酪氨酸残基磷酸化,从而传递信号,在细胞增殖、分化、迁移和凋亡中起重要作用。酪氨酸激酶的异常表达将导致细胞增殖调节发生紊乱,还与肿瘤的侵袭与转移、肿瘤新生血管的生成、肿瘤的化疗抗性密切相关。
发明内容
针对现有技术中的上述不足,本发明提供一种含苯并噻吩嘧啶衍生物及其制备方法和在制备抗肿瘤药物中的应用,制备得到的含苯并噻吩嘧啶衍生物具有优异的体内抗肿瘤活性,体内抑瘤率TGI值为90.24%。
为实现上述目的,本发明解决其技术问题所采用的技术方案是:

本发明的有益效果:
本发明设计并合成了13个新结构的嘧啶衍生物。研究结果表明优选化合物6a(Ⅵ-1)对EGFR L858R/T790M高表达激酶和EGFR L858R/T790M高表达细胞H1975均具有良好的抑制作用,IC50值分别为0.26nM和2.2nM。机制研究表明6a可以时间-剂量依赖性的抑制EGFR和AKT磷酸化蛋白的表达,从而诱导H1975细胞凋亡。此外,6a对三种人正常细胞株均表现出较小的细胞毒性,并且优于阳性对照药物奥希替尼。进一步研究表明,6a具有良好的药代动力学特性。最后,体内活性研究显示化合物6a有很好的体内抗肿瘤活性,其体内抑瘤率TGI值为90.24%。上述结果表明6a在非小细胞肺癌(NSCLC)治疗中值得进一步研究。

实施例2激酶测试实验
为了确定6a的靶向性并评估其抗肿瘤潜力,我们进行了体外酶学检测。以Afatinib和Osimertinib作为阳性对照。如图1所示,图1(A)为6a诱导了EGFR磷酸化的剂量依赖性抑制;(B)为Afatinib和Osimertinib诱导了EGFR磷酸化的剂量依赖性抑制。数据以三次重复独立实验的平均值±标准差表示。
其中,6a在纳米摩尔浓度水平上表现出较强的抑制活性,且呈剂量依赖性(EGFR-L858R的IC50=1.33±0.02nM),与阳性对照Afatinib的IC50=1.03±0.03nM相似。对于EGFR T790M/L858R突变,6a的抑制作用(IC50=0.26±0.01nM)略强于Osimertinib(IC50=0.37±0.04nM),说明6a具有克服EGFR突变抗性的潜力。
实施例3苯并噻吩嘧啶衍生物的抗肿瘤活性研究
以Osimertinib为阳性对照,测定合成的13个化合物对H1975,PC9,H229细胞的体外抗增殖活性,具体过程为:
收集对数期细胞,调整细胞悬液浓度,以5×103个/孔接种到96孔板中,置37℃、5%的二氧化碳培养箱孵育12-24h。待细胞贴壁后,吸弃旧培养基,加入不含有FBS的培养基;每一化合物设六个浓度梯度(10、1、0.1、0.05、0.01、0.001μM),每一浓度设三组复孔,加入后,培养48h然后每孔避光加入CCK8溶液,放入二氧化碳培养箱继续孵育2-4h。在酶标仪在450nM的发射波长下测定各孔光的吸光度(OD值)。最后进行数据统计,根据下列公式算得各浓度下的抑制率:
Figure BDA0003398823680000141
然后利用软件GraphPad Prism 5.02计算半数抑制量(IC50),每一组实验独立重复三次并取平均值获取最终数据。具体实验结果如表1所示。

a.EGFR激酶L858R/T790M双突变细胞;b.EGFR激酶L858R单突变细胞;c.EGFR激酶野生型细胞。
体外抗增殖实验结果表明:化合物Ⅵ-1对H1975细胞的抗增殖活性为2.2nM,是阳性药Osimertinib的1.58倍;同时化合物Ⅵ-1与阳性药相比,对双突变的H1975细胞具有更高的选择性。化合物Ⅵ-2~Ⅵ-12和Ⅵ-13体外抗增殖活性均弱于Ⅵ-1。
对13个Osimertinib衍生物的体外抗增殖活性研究结果表明,将N-甲基吲哚环用疏水性较大的杂环取代,有利于抗增殖活性的增加,说明该部分结构与靶点的结合需要疏水作用,另外,化合物Ⅵ-1对H1975细胞的高选择性,进一步验证了该类化合物的毒性有一部分来源于N-甲基吲哚的去甲基化反应;对R2部分的结构修饰,无论是改变链的体积、电性或脂溶性,均使活性降低,这可能由于改变了分子的空间构象,使小分子不能与靶蛋白有效的结合,也说明侧链结构具有较高的保守性;将R1用氟原子取代后,抗增殖活性降低,可能由于该处与靶点的结合位点较小,体积增大后不能有效的与靶蛋白结合。
