The synthesis and biochemical evaluation of novel cyanothiazolidine inhibitors of dipeptidyl peptidase 4 (DPP4) is described. Their main structural feature is a constrained bicyclic core that prevents the intramolecular formation of inactive cyclic species. The inhibitors show good to moderate biochemical potency against DPP4 and display distinct selectivity profiles towards DPP7, DPP8 and DPP9 depending on their substitution. (C) 2009 Elsevier Ltd.

Certain constrained cyano compounds are useful as inhibitors of post-proline/alanine cleaving amino-dipeptidases. Accordingly, these compounds can be employed, , alone or with another therapeutic agent, to treat diabetes (especially, Type II diabetes), hyperglycemia, Syndrome X, diabetic complications, hyperinsulinemia, obesity, atherosclerosis and related diseases, as well as various immunomodulatory diseases and chronic inflammatory bowel disease.
