Abstract :
A series of β-aminoacylpiperidines bearing various fused five-membered heterocyclic rings was synthesized as dipeptidyl peptidase IV inhibitors. Potent and relatively selective inhibition could be obtained, depending on choice of heterocycle, regioisomerism, and substitution. In particular, one analog (74, DPP-IV IC50 = 26 nM) exhibited good oral bioavailability and acceptable half-life in the rat, albeit with rather high clearance.
