Synthesis and Pharmacological Characterization of Chiral Pyrrolidinylfuran Derivatives: The Discovery of New Functionally Selective Muscarinic Agonists
further characterizing subtypes of cholinergic receptors. Unlike their parent compounds, the new molecules lack nicotinic activity, being pure muscarinic ligands. While binding studies on the five cloned human muscarinicreceptors showed no subtype selectivity, functional assays revealed that some of the molecules of the series are potent M 2 selective partial agonists with interesting pharmacological
