Potent Anti-Muscarinic Activity in a Novel Series of Quinuclidine Derivatives

Bioorg Med Chem Lett. 2006 Jan 15;16(2):373-7. doi: 10.1016/j.bmcl.2005.09.079. Epub 2005 Nov 3.

Abstract

The synthesis and biological evaluation of a novel family of M(3) muscarinic antagonists are described. A systematic modification of the substituents to a novel alkyne-quinuclidine scaffold yielded original compounds displaying potent in vitro anticholinergic properties.
