WNT信号是一个复杂的蛋白质作用网络,在哺乳动物的胚胎发育、正常生理过程和一些疾病的发生过程中起着至关重要的作用.人们常把WNT信号通路分为WNT/β-连环蛋白信号通路(经典的WNT信号通路或β-连环蛋白依赖性WNT信号通路)和非经典WNT信号通路(或β-连环蛋白非相关性WNT信号通路).其中WNT/β连环蛋白信号通路是目前研究的比较清楚的一条WNT信号通路.Pyrvinium,化学名(E)-6-二甲胺基-2-[2-(2,5-二甲基-1-苯基吡咯-3-基)乙烯基]-1-甲基喹啉,可作为早期的驱虫药和花青类染料.研究发现pyrvinium 在抑制WNT/β-连环蛋白信号通路方面有较高活性.因此,研究WNT信号通路抑制剂pyrvinium及其衍生物的合成具有重要意义.本研究参考相关文献,通过经典Doebner-Miller 喹啉合成法和Paal-Knorr吡咯合成法分别得到了两个关键切块,最后通过Aldol缩合得到目标化合物.合成的pyrvinium三氟甲磺酸盐(结构如图l所示)总收率为28.8%与文献报道碘化pyrvinium的总收率为14.1%在收率上有了很大的提高.另外,在操作中我们还对反应路线中的一些中间体的合成方法和后处理方法进行了优化,使操作更简单易行.
