Description
技术领域
本发明涉及含吡唑啉结构的噻吩并嘧啶类化合物,其几何异构体及其药学上可接受的盐、水合物、溶剂化物或前药,它们的制备方法以及含有所述化合物的药物组合物。
背景技术
肿瘤是机体在各种致瘤因素作用下,局部组织的细胞在基因水平上失去对其生长的正常调控导致异常增生与分化而形成的新生物。新生物一旦形成,不因病因消除而停止生长,他的生长不受正常机体生理调节,而是破坏正常组织与器官,这一点在恶性肿瘤尤其明显。与良性肿瘤相比,恶性肿瘤生长速度快,呈浸润性生长,易发生出血、坏死、溃疡等,并常有远处转移,造成人体消瘦、无力、贫血、食欲不振、发热以及严重的脏器功能受损等,最终造成患者死亡。由于PI3K通路,在肿瘤的发生和发展中具有重要的作用,因此以PI3K/Akt信号通路中关键分子为靶点的小分子抑制剂已成为当前抗肿瘤药物研究的热点,近年来,随着PI3K通路抑制剂的深入研究,越来越多的相关抑制剂被报道,其中一批脂肪环并嘧啶类化合物被证实具有很好的PI3K/mTOR抑制活性以及良好的体内、药代动力学活性。文献报道的GDC-0941(如下结构式所示)属于噻吩并嘧啶类化合物,是由Genentech公司开发的口服PI3K抑制剂,目前已完成I期临床试验。GDC-0941对p110α和δ的IC50值均达到3nM,为p110β、γ的10倍和25倍,具有良好的选择性。临床前研究表明,GDC-0941对多种人肿瘤细胞株表现出显著的抑制增殖作用,其IC50值达0.009ug/mL。课题组前期工作中以GDC-0941为先导化合物,进一步改造得到的化合物A也表现出了良好的抗肿瘤活(如下结构式所示),文献(Synthesis,characterization and pharmacological study of 4,5-dihydropyrazolines carrying pyrimidine moiety[J].European journal ofmedicinal chemistry,55(2012)467-474.)和(Novel 3,5-diaryl pyrazolines as humanBioorganic&Medicinal Chemistry Letters 14(2004)2715–2717)报道了一系列新颖的吡唑啉衍生物,其中化合物B,C,D显示出非常优良的抗肿瘤活性。GDC-0941、化合物A、B,C,D的结构式如下:
本发明设计合成了一系列噻吩并嘧啶类化合物,此系列化合物保留了噻吩并嘧啶的主体结构的同时引入了吡唑啉活性基团,设计并合成了多种噻吩并嘧啶类化合物。本发明着重考察的是不同取代的噻吩并嘧啶类化合物的抗肿瘤活性,以期筛选出活性与选择性更佳的抗肿瘤药物。经体外对多种PI3K/mTOR抑制剂高表达细胞株进行抗肿瘤活性筛选,结果表明具有较强的抗肿瘤活性和选择性,许多化合物还进行了PI3Kα和mTOR激酶的体内活性测试。实验表明某些化合物具有高效的抗肿瘤活性。

此外,本发明还包括本发明衍生物的前药。本发明衍生物的前药是上述通式I的衍生物,它们自身可能具有较弱的活性甚至没有活性,但是在给药后,在生理条件下(例如通过代谢、溶剂分解或另外的方式)被转化成相应的生物活性形式。
本发明可以含有上述通式I的含吡唑啉结构的噻吩并嘧啶类化合物,及其药学上可接受的盐、水合物或溶剂化物作为活性成份,与药学上可接受的载体或赋型剂混合制备成组合物,并制备成临床上可接受的剂型,上述药学上可接受的赋型剂是指任何可用于药学领域的稀释剂、辅助剂和/或载体。本发明的衍生物可以与其他活性成份组合使用,只要它们不产生其他不利的作用,例如过敏反应。
本发明上述通式I的含吡唑啉结构的噻吩并嘧啶类化合物用于患者的临床剂量可以根据:活性成分在体内的治疗功效和生物利用度、它们的代谢和排泄速率和患者的年龄、性别、疾病期来进行适当调整,不过成人的每日剂量一般应当为20~600mg,优选为60~400mg。因此,当本发明的药物组合物被制成单位剂型时,考虑到上述有效剂量,每单位制剂应当含有20~600mg上式通式Ⅰ的含吡唑啉结构的噻吩并嘧啶类化合物,优选为60~400mg。按照医生或药师的指导,这些制剂可以以一定间隔分若干次给药(优选为一至五次)。

1)细胞复苏并传代2~3次稳定后,用胰蛋白酶溶液(0.25%)使其从培养瓶底部消化下来。将细胞消化液倒入离心管中后,之后加入培养液以终止消化。将离心管在800r/min下离心10min,弃去上清液后加入5mL培养液,吹打混匀细胞,吸取10μL细胞混悬液加入细胞计数板中计数,调整细胞浓度为104个/孔。96孔板中除A1孔为空白孔不加细胞外,其余皆加入100μL细胞混悬液。将96孔板放入培养箱中培养24h。
2)用50μL二甲基亚砜溶解受试样品,然后加入适量培养液,使样品溶解成2mg/mL药液,然后在24孔板中将样品稀释为20、4、0.8、0.16、0.032μg/mL。
每个浓度加入3孔,其中周围两行两列细胞长势受环境影响较大,只和为空白细胞孔使用。将96孔板放入培养箱中培养72h。
3)将96孔板中带药培养液弃去,用磷酸缓冲溶液(PBS)将细胞冲洗两遍,在每孔中加入MTT(四氮唑)(0.5mg/mL)100μL放入培养箱中4h后,弃去MTT溶液,加入二甲基亚砜100μL。在磁力振荡器上振荡使存活细胞与MTT反应产物充分溶解,放入酶标仪中测定结果。通过Bliss法可求出药物IC50值。
化合物的肝癌细胞HepG2、肺癌细胞A549、前列腺癌PC-3活性结果见表2。
实验结果如表2所示。表1中IC50>=80%,以“+++”表示,80%>IC50>=60%,以“++”表示,60%>IC50>=40%,以“+”表示,IC50<=40%,以“-”表示,“NA”表示无活性,“ND”表示未测试。
