  Design and synthesis of DPP-IV inhibitors lacking the electrophilic nitrile group

  摘要：

  A series of (4 beta-substituted)-L-prolylpyrrolidine analogs lacking the electrophilic nitrile function were synthesized and their dipeptidyl peptidase IV (DPP-IV) inhibitory activity and duration of ex vivo activity were evaluated. Structural optimization of a N-(3-phenyl-1,2,4-thiadiazol-5-yl) piperazine analog 8, which was found by high-speed analog synthesis, was carried out to improve the potency and duration of action. A representative compound 26 was evaluated to assess its effect on the plasma glucose level after the oGTT (oral glucose tolerance test) in normal rats. Structure-activity relationships (SAR) are also presented. (C) 2007 Elsevier Ltd. All rights reserved.
