dipeptidyl peptidase II (DPP II) inhibitors. gamma-Aminosubstitution with arylalkyl groups, for example, a 2-chlorobenzyl moiety, resulted in a DPP II inhibitor with an IC(50) = 0.23 nM and a high selectivity toward DPP IV (IC(50) = 345 microM). Furthermore, it was shown that the basicity of the gamma-amino is important and that alpha-amino substitution is not favorable. Piperidine-2-nitriles did not
