phenylphosphonic acid, and a rigid conformer produced by an internal salt bridge between the phosphonate and the alpha-amino group. Replacement of the phosphonic acid moiety with a phosphinic or carboxylic acid as well as deletion of the benzyl substitution of the alpha-amino group led to great reductions in potency.
对人前列腺酸磷酸酶的一系列苄基膦酸抑制剂的结构要求的进一步研究导致了一系列高效的α-氨基苄基膦酸。IC50 = 4 nM的α-苄基氨基苄基膦酸的效能比碳类似物α-苯乙基提高了3500倍。增强的效力可能是由于四种有利相互作用的组合,包括与磷酸盐结合区的相互作用,苄氨基和苯基膦酸的疏水部分的存在以及膦酸酯和α-之间的内部盐桥产生的刚性构象异构体。氨基。
