摘要:
A series of imidazo[1,2-a] pyridine derivatives was identified and evaluated for MCH1R binding and antagonistic activity. Introduction of a methyl substituent at the 3-position of imidazo[1,2-a] pyridine provided compounds with a significant improvement in MCH1R affinity. Representative compounds in this series exhibited good potency and brain exposure in rats. (C) 2009 Elsevier Ltd. All rights reserved.
