Arylpropionylpiperazines as antagonists of the human melanocortin-4 receptor
摘要:
A series of 3-arylpropionylpiperazines were synthesized as antagonists of the melanocortin-4 receptor. Their potency was found to be increased by replacing the alpha-methyl substituent of the initial lead 11 with a larger s-Bu or i-Bu group. Further potency enhancement was observed when a glycine or beta-alanine was incorporated onto the benzylamine. Some compounds demonstrated good potency, moderate selectivity, and oral bioavailability. (c) 2006 Elsevier Ltd. All rights reserved.
