Using 1-[(S)-2,4-diaminobutanoyl]piperidine as lead compound, we developed a large series of highly potent and selective dipeptidyl peptidase II (DPP II) inhibitors. γ-Amino substitution with arylalkyl groups, for example, a 2-chlorobenzyl moiety, resulted in a DPP II inhibitor with an IC50 = 0.23 nM and a high selectivity toward DPP IV (IC50 = 345 μM). Furthermore, it was shown that the basicity of the γ-amino is important and that α-amino substitution is not favorable. Piperidine-2-nitriles did not show an increase in potency but rather reduced the selectivity. Introduction of a 4-methyl or a 3-fluorine on piperidine improved selectivity and preserved the high potency.

In this paper we report the systematic search for new, potent, and selective DPP II inhibitors. A study of the structure-activity relationship was conducted starting from aminoacyl pyrrolidides as lead compounds. Rational exploration of the P1
