title: Novel imidazole derivatives with subtype-selective antimuscarinic activity (1).
abstract: A series of N-substituted 4-amino-2,2-diphenylbutyramide derivatives was prepared as part of a search for subtype-selective antimuscarinic agents. The representative compound KRP-197, bearing a 2-methylimidazole ring as a surrogate of aliphatic amine, was found to be a highly potent and both M1- and M3-selective antimuscarinic agent.
