The present invention relates to pyrrolidine-based compounds of novel structure exhibiting good inhibitory activity versus Dipeptidyl Peptidase-IV, as defined in Formula 1 of the specification, and methods of preparing the same and pharmaceutical compositions containing the same as an active agent.
Synthesis of a novel series of DPPIV inhibitors with 1,2,4- and 1,3,4-oxadiazolyl ketone derivatives and its structure-activity relationships are discussed. Compound 18h showed good inhibitory activity against DPPIV and favorable pharmacokinetic properties. In vivo pharmacodynamic efficacy and co-crystal structure of compound 18h with DPPIV is also described. (c) 2007 Elsevier Ltd. All rights reserved.
