To discover a highly selective M-3 antagonist, a combinatorial library was prepared. The library was designed to identify a novel structural class of M-3 antagonists by exploring the spatial arrangement of the pharmacophores in known M-3 antagonists. After the evaluation of 1000 library members, a potent M-3 antagonist, 14a (K-i = 0.31 nM), with novel structural features was identified. Compound 14a showed high selectivity for M3 receptors over the other muscarinic receptor subtypes (M-1/M-3 = 380-fold, M-2/M-3 = 98-fold, M-4/M-3 = 45-fold, M-5/M-3 = 120-fold).
