The structure–activity relationship of various N-alkyl Gly-boro-Pro derivatives against three
dipeptidyl peptidases (DPPs) was studied. In a series of N-cycloalkyl analogs, DPP4 and
fibroblast activation protein-α (FAP) optimally preferred N-cycloheptyl whereas DPP7
tolerated even larger cycloalkyl rings. Gly α-carbon derivatization of N-cyclohexyl or N-(2-
adamantyl) Gly-boro-Pro resulted in a significant decrease in potency against all the three
DPPs.
