  Design, Synthesis and Biological Evaluation of Imidazo[1,2-a]pyridine Derivatives as Novel DPP-4 Inhibitors

  摘要：

  A new series of DPP‐4 inhibitors with imidazo[1,2‐a]pyridine scaffold were designed by exploiting scaffold hopping strategy and docking study. Based on docking binding model, structural modifications of 2‐benzene ring and pyridine moieties of compound 5a led to the identification of compound 5d with 2, 4‐dichlorophenyl group at the 2‐position as a potent (IC50 = 0.13 μm), selective (DPP‐8/DPP‐4 = 215 and DPP‐9/DPP‐4 = 192) and in vivo efficacious DPP‐4 inhibitor. Further, molecular docking revealed that compound 5d could retain key binding features of DPP‐4 with the pyridine moiety of imidazo[1,2‐a]pyridine ring providing an additional π−π interaction with Phe357 of DPP‐4. Compound 5d might be a promising lead for further development of novel DPP‐4 inhibitor treating T2DM.

  日期：——

  A direct method for the synthesis of formyl-substituted imidazo[1,2-a]pyridines was achieved easily from cyclization of aminopyridines and cinnamaldehydes via copper catalysis. This oxidative cyclization process involved direct C–H bond functionalization, and C–C/C–N bond formation. In this transformation, the sensitive aldehyde group was preserved under oxidative conditions.
