A potent, long-acting, orally active (2R)-2-[(1R)-3,3-difluorocyclopentyl]-2-hydroxy-2-phenylacetamide: A novel muscarinic M3 receptor antagonist with high selectivity for M3 over M2 receptors
A novel series of (2R)-2-[(1R)-3,3-difluorocyclopentyl]-2-hydroxy-2-phenylacetamides was designed and synthesized based on the structure and biological profiles of an active metabolite 2 of our prototype muscarinic M3 receptor selective antagon
