An efficient method has been developed for the first solid-phase synthesis of HTLV-1 protease inhibitors that contain hydroxyethylamine isostere as a transition-state mimetic. The synthetic procedure was designed to allow the evaluation of stereostructure-activity relationships at the scissile site. All the possible configurations at the hydroxy- and side chain-bearing asymmetric centers of the isostere
已经开发出一种有效的方法,用于第一次固相合成HTLV-1蛋白酶抑制剂,该抑制剂含有羟乙基胺等排物作为过渡态模拟物。设计合成程序以允许评估易位部位的立体构效关系。通过酯衍生的不对称醛醇缩合反应,构建了等位基因的羟基和侧链不对称中心的所有可能构型。通过使用新开发的琥珀酸酯接头,在固相支持物上合成了包含等排骨架的每种抑制剂。羟基和侧链不对称中心的构型对抑制活性表现出显着的影响。K(i)值大约变化2个数量级。
