A series of novel alkynyl substituted 3,4-dihydropyrimidin-2(1H)-one (DHPM) derivatives were designed, synthesized and evaluated in vitro as potential inhibitors of chorismate mutase (CM). All these compounds were prepared via a multi-component reaction (MCR) involving sequential I2-mediated Biginelli reaction followed by Cu-free Sonogashira coupling. Some of them showed promising inhibitory activities
一系列新颖的炔基的取代的3,4-二氢嘧啶-2(ħ) -酮(DHPM)衍生物设计,合成并评价在体外作为分支酸变位酶(CM)的潜在抑制剂。所有这些化合物都是通过多组分反应(MCR)制备的,该反应涉及顺序的I 2介导的Biginelli反应,然后进行无铜Sonogashira偶联。当以30μM进行测试时,其中一些显示出有希望的抑制活性。一种化合物表现出对CM的剂量依赖性抑制,IC 50值为14.76± 0.54μM,表明邻炔基苯基取代的DHPM是发现有希望的CM抑制剂的新支架。
