  • PubMed Abstract: 

    A novel series of non-covalent, benzimidazole-based inhibitors of DPP-4 has been developed from a small fragment hit using structure-based drug design. A highly versatile synthetic route was created for the development of SAR, which led to the discovery of potent and selective inhibitors with excellent pharmaceutical properties.
