series of 4-aminophenylalanine and 4-aminocyclohexylalanine derivatives were designed and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-4). The phenylalanine series afforded compounds such as 10 that were potent and selective (DPP-4, IC(50)=28nM), but exhibited limited oral bioavailability. The corresponding cyclohexylalanine derivatives such as 25 afforded improved PK exposure and efficacy
设计了一系列新颖的4-氨基苯丙氨酸和4-氨基环己基丙氨酸衍生物,并将其评估为二肽基肽酶IV(DPP-4)的抑制剂。苯丙氨酸系列提供了有效的和选择性的化合物(如10)(DPP-4,IC(50)= 28nM),但口服生物利用度有限。相应的环己基丙氨酸衍生物(如25)在鼠类OGTT实验中提供了改善的PK暴露和功效。呈现了结合到DPP-4活性位点的25的X射线晶体结构。
