Synthesis of 3-(1,2,3-triazol-1-yl)- and 3-(1,2,3-triazol-4-yl)-substituted pyrazolo[3,4-d]pyrimidin-4-amines via click chemistry: potential inhibitors of the Plasmodium falciparum PfPK7 protein kinase

3-(1,2,3-triazol-1-yl)- and 3-(1,2,3-triazol-4-yl)pyrazolo[3,4-d]pyrimidin-4-amines using a one-pot two-step reaction are presented. The two routes give easy access to two different isomers of 1,4-disubstituted triazoles and the target compounds are obtained from a variety of readily available aromatic and aliphatic halides without isolation of potentially unstable organic azide intermediates. Two compounds
使用a到3-(1,2,3-三唑-1-基)-和3-(1,2,3-三唑-4-基)吡唑并[3,4- d ]嘧啶-4-胺的有效途径介绍了一锅两步反应。这两种途径使1,4-二取代的三唑的两种不同的异构体容易接近,并且目标化合物是从各种容易获得的芳族和脂族卤化物中获得的,而无需分离潜在的不稳定的有机叠氮化物中间体。两种化合物对P的PfPK7激酶(IC 50 10–20 µM)具有活性。恶性疟原虫,是造成疟疾毒性最强的一种生物,可以被视为对进一步发展成铅化合物有用的命中物。
