摘要:
Based on 3-phenylpropionamides, a series of 3-arylpyrrolidine-2-carboxamide derivatives was designed and synthesized to study the effect of cyclizations as melanocortin-4 receptor ligands. It was found that the 2R, 3R-pyrrolidine isomer possessed the most potent affinity among the four stereoisomers. (C) 2008 Elsevier Ltd. All rights reserved.
