(2S)-cyanoPro scaffold as a possible entry to highly potent and selective FAP inhibitors. In the present study, we explore in detail the structure–activityrelationship around this core scaffold. We report extensively optimized compounds that display low nanomolar inhibitory potency and high selectivity against the related dipeptidylpeptidases (DPPs) DPPIV, DPP9, DPPII, and prolyl oligopeptidase (PREP)
Design, synthesis and biological evaluation of the imidazopyridine analogs as novel GSK3β inhibitors for treatment of type 2 diabetes mellitus are described. Most of the analogs exhibited excellent inhibitory activities (IC50 < 44 nM) against glycogen synthase kinase 3β (GSK3β). The structure–activity relationship (SAR) of the imidazopyridine analogs and the binding mode of analog 23 in the catalytic
