摘要:
This Letter describes the synthesis and SAR, developed through an iterative analog library approach, of a novel series of selective M-1 mAChR antagonists, based on an N-(4-(4-alkylpiperazin-1-yl)phenyl)benzamide scaffold for the potential treatment of Parkinson's disease, dystonia and other movement disorders. Compounds in this series possess M-1 antagonist IC(50)s in the 350 nM to >10 mu M range with varying degrees of functional selectivity versus M-2-M-5. (C) 2010 Elsevier Ltd. All rights reserved.
