Design, synthesis, and evaluation of proline based melanocortin receptor ligands
摘要:
A series of proline based melanocortin ligands has been developed on the basis of initial piperazine leads by using a more conformationally rigid scaffold. A number of these novel ligands showed significant binding affinity for MC3 and MC4 receptors. (c) 2005 Elsevier Ltd. All rights reserved.

L-arginine derivatives were designed, synthesized and assayed for their activities against amino-peptidase N (APN)/CD13 and metalloproteinase-2 (MMP-2). The results showed that most compounds exhibited high inhibitory activities against APN and low activities against MMP-2. Within this series, two compounds 5q and 5s (IC(50)=5.3 and 5.1 microM) showed similar inhibitory activities compared with bestatin
