title: A potent dipeptide inhibitor of dipeptidyl peptidase IV.
abstract: A series of novel potent inhibitors of dipeptidyl peptidase IV (DPP-IV) has been developed. A brief structure-activity relationship of the inhibitors was investigated. The dipeptide TSL-225, tryptophyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, was identified with the critical structure for the inhibitory activity.
