covalently by nucleophilic substitution to the serine residue in the active site of serine proteases, similarly to the diphenyl phosphonates used as standard. The synthesis of these compounds as well as their phosphonylating reactivity towards methanol, which served as mimetic of the serine nucleophile, is described. The stereochemistry of the substitution in basic solutions was studied in some detail
与用作标准的二苯基膦酸酯相似,已经设计了O-苯基磷酸亚氨基酸酯通过亲核取代与丝氨酸蛋白酶活性位点中的丝氨酸残基共价结合。描述了这些化合物的合成以及它们对甲醇的膦酰化反应性,其充当了丝氨酸亲核试剂的模拟物。详细研究了基本溶液中取代的立体化学。氨基磷酸膦酸酯在水溶液中的稳定性以及它们在对抗醇与硫醇的反应中的选择性证明,它们构成了一类潜在的丝氨酸蛋白酶抑制剂,并且是研究抑制机理的有价值的工具。
