The 4-hydroxy-5,6-dihydropyrone template was utilized as a flexible scaffolding from which to build potent active site inhibitors of HIV protease. Dihydropyrone 1c (5,6-dihydro-4-hydroxy-6-phenyl-3-[(2-phenylethyl)thio]-2H-pyran-2-one) was modeled in the active site of HIV protease utilizing a similar binding mode found for the previously reported 4-hydroxybenzopyran-2-ones. Our model led us to pursue
4-羟基-5,6-二氢吡喃酮模板被用作柔性支架,从该支架可构建有效的HIV蛋白酶活性位点抑制剂。使用类似的结合模式在HIV蛋白酶的活性位点中模拟了二氢吡喃酮1c(5,6-二氢-4-羟基-6-苯基-3-[(2-苯基乙基)硫代] -2H-吡喃-2-酮)发现为先前报道的4-羟基苯并吡喃-2-酮。我们的模型导致我们追求6,6-二取代的二氢吡喃酮的合成,目的是填充S1和S2,从而提高未填充S2的母体二氢吡喃酮1c的效力。为此,我们在二氢吡喃酮的6-位连接了各种疏水和亲水侧链,以模拟天然和非天然氨基酸,已知它们是P2和P2'的有效底物。将母体二氢吡喃酮1c(IC50 = 2100 nM)制成化合物,其效力提高了100倍以上[18c,IC50 = 5 nM,5-(3,6-dihydro-4-hydroxy-6-oxo-2-苯基-5- [2-苯基乙基)硫代] -2H-吡喃-2-基)戊酸和12c,IC50 =
