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.
(-) and (+) alpha-Allokainoids hydrochlorides 3 and 4 were obtained by hydrolysis of the corresponding Michael adducts resulting from the addition of diethyl malonate to chiral N-urethane protected ethyl 4-benzyl-2,3-didehydroprolinates 9 and 13 respectively.
