hydroxyl groups required for optimal inhibition of the HIV-1 protease were determined to be the C-3R and C-4R, i.e. the l-manno-configuration. Three C2-symmetric inhibitors were converted to their thiocarbonates and reduced to provide the corresponding hydroxyethyl transition-state mimics. Deletion of the C-4 hydroxyl group in these inhibitors gave no further improvement in the anti-viral activity
已经研究了中心羟基对衍生自1-马来酸的对称HIV-1蛋白酶抑制剂的抗病毒活性的影响。合成1-Iditol,并将其用作手性前体,用于合成在C-3和C-4具有反向构型的相应抑制剂。关键中间体是3,4- O-异亚丙基-1-ID醇和活化的1-二十二酸琥珀酰亚胺酯。确定最佳抑制HIV-1蛋白酶所需的中心羟基的构型为C- 3R和C- 4R,即1-甘露聚糖构型。三C 2不对称抑制剂被转化为其硫代碳酸盐并被还原以提供相应的羟乙基过渡态模拟物。这些抑制剂中C-4羟基的缺失没有进一步提高抗病毒活性。
