Design, synthesis and biological evaluation of novel aminomethyl-piperidones based DPP-IV inhibitors

A series of novel aminomethyl-piperidones were designed and evaluated as potential DPP-IV inhibitors. Optimized analogue 12v ((4S,5S)-5-(aminomethyl)-1-(2-(benzo[d][1,3]dioxol-5-yl)ethyl)-4-(2,5-difluorophenyl)piperidin-2-one) showed excellent in vitro potency and selectivity for DPP-IV over other serine proteases. The lead compound 12v showed potent and long acting antihyperglycemic effects (in vivo), along with improved pharmacokinetic profile.
