In this paper, we report the synthesis of diastereomerically pure N-(4-substituted-2,4-diaminobutanoyl)piperidines. These compounds were prepared to investigate the influence of the 4-substitution on the dipeptidyl peptidase II (DPP II) activity and selectivity of the parent N-(2,4-diaminobutanoyl)piperidine. The (4S)-methyl compound showed subnanomolar inhibition, comparable with the parent compound. The (4R)-methyl group or bigger substituents decreased the activity.
