Description
技术领域
本发明涉及含四氢吡啶并[4,3-d]嘧啶衍生物及其光学异构体、药学上可接受的盐、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。本发明还涉及所述化合物较强的ATX激酶和EGFR激酶抑制作用,并且还涉及该类化合物及其光学异构体、药学上可接受的盐在制备用于治疗和/或预防由于ATX和EGFR异常表达所引起疾病的药物中的应用,特别是在制备治疗和/或预防纤维化和癌症的药物中的用途。
背景技术
纤维化过程是组织损伤后的一种病理愈合过程,是很多慢性疾病进展的共同通路,最终将导致器官的结构改变和功能减退,主要包括肺纤维化、心肌纤维化、肝纤维化以及肾纤维化等。其中,肺纤维化是由多种原因引起弥漫性肺部炎性疾病的共同结局,导致呼吸功能严重障碍,以肺泡上皮损伤、肌成纤维细胞聚集及ECM过度沉积为特征;心肌纤维化(myocardialfibrosis, MF)是指在心肌细胞外基质(extracellularmatrix,ECM)中胶原纤维过量积聚、胶原含量显著升高或胶原成分发生改变。
自分泌运动因子(ATX)是在20世纪90年代初发现于A2058黑素瘤细胞,是一个由约900个氨基酸组成的蛋白质,是一种自分泌型的溶血磷脂酶D,属于ENPP受体家族成员之一。它是ENPP家族中唯一能将溶血磷脂酰胆碱(LPC)转化为溶血磷脂酸的成员。ATX最初是作为治疗癌症的靶点被开发利用的,近期的研究表明,ATX-LPA信号通过调节肺上皮细胞,成纤维细胞和平滑肌细胞,在肺纤维化和肺部炎症疾病中发挥重要作用。ATX作为治疗肺纤维化的靶点现已被广泛应用于新药的研发,并且已经有ATX抑制剂处于II期临床研究。此外,我们的研究发现,ATX抑制剂在心肌纤维化的治疗中也显现出了优异的效果。
肺癌是威胁人类健康最大的疾病之一,其中非小细胞肺癌(Non-small cell lungcancer, NSCLC)患者占肺癌患者总数的约80%~85%,是肺癌中最为常见的组织学类型,也是全球死亡人数最多的恶性肿瘤。表皮生长因子受体(EGFR)于1987年首次被报道用于治疗非小细胞肺癌;其可以激活下游Ras/Raf/MAPK、PI3K/AKT/mTOR和JAK/STAT三条信号通路,传导至细胞核内,控制DNA分子的复制,进而完成细胞的增殖分化。经过30多年的发展,EGFR 抑制剂已被广泛用于非小细胞肺癌的治疗,新型抗突变耐药的EGFR抑制剂的研发仍是抗肿瘤药物研发的热点。
本发明设计并合成了一系列四氢吡啶并[4,3-d]嘧啶衍生物。经体外活性筛选,表明该类化合物具有明显的抗纤维化和抗肿瘤活性。

(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(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反应产物甲臜充分溶解,放入酶标仪中测定结果。通过Bliss法可求出药物IC50值。
