Like most phosphonic acids, the recently discovered potent and selective thiazole phosphonic acid inhibitors of fructose 1,6-bisphosphatase (FBPase) exhibited low oral bioavailability (OBAV) and therefore required a prodrug to achieve oral efficacy. Syntheses of known phosphonate prodrugs did not afford the desired OBAV; hence, a new class of prodrugs was sought. Phosphonic diamides derived from amino
像大多数膦酸一样,最近发现的果糖1,6-双磷酸酶(FBPase)的有效和选择性噻唑膦酸抑制剂表现出较低的口服生物利用度(OBAV),因此需要前药才能达到口服功效。已知的膦酸酯前药的合成不能提供所需的OBAV。因此,寻求一种新的前药。已发现衍生自氨基酸酯的膦酸二酰胺是可行的前药,它满足了我们预先设定的目标:在宽pH范围内具有出色的水稳定性,良性副产物(氨基酸和低分子量醇),最重要的是良好的OBAV,可产生坚固的口服葡萄糖降低效果。膦二酰胺的这些所需特性代表了对现有前药类别的显着改进。
