Muscarinic antagonists with multiple stereocenters: Synthesis, affinity profile and functional activity of isomeric 1-methyl-2-(2,2-alkylaryl-1,3-oxathiolan-5-yl)pyrrolidine sulfoxide derivatives
摘要:
Completing a long-lasting research on 1,3-oxathiolane muscarinic ligands, we have synthesized a set of isomeric 1-methyl-2-( 2,2-alkylaryl-1,3-oxathiolan-5-yl) pyrrolidine 3-sulfoxide derivatives, containing three or four stereogenic centers. In general the compounds are very potent antagonists even if, unlike the corresponding agonists, they show modest subtype selectivity. (C) 2008 Elsevier Ltd. All rights reserved.
Synthesis, Affinity Profile, and Functional Activity of Muscarinic Antagonists with a 1-Methyl-2-(2,2-alkylaryl-1,3-oxathiolan-5-yl)pyrrolidine Structure
studied muscarinic ligand, characterized by a 1,3-oxathiolane nucleus, a new series of muscarinicantagonists were designed by increasing the stereochemical complexity of the molecules. A small library of enantiomeric and diastereomeric 2,2-diphenyl- and 2-cyclohexyl-2-phenyl substituted compounds was thus obtained. All the tested compounds show a high affinity toward cloned human muscarinic hm1-hm5
