Imidazole compounds

摘要

Compounds represented by general formula (I) or pharmacologically acceptable salts thereof, wherein Y represents hydrogen, cyano or carbamoyl; Z represents CH or nitrogen; -A-B- represents -CH2-CH2- or -CH=CH-; m is 1 or 2; and n is 0 or 1. Because of having an extremely potent and selective antagonism to muscarine M3 receptor, these compounds are useful as preventives or remedies for diseases in which muscarine M3 receptor participates. In addition, these compounds can provide safe drugs scarcely causing thirst which is a side effect of muscarine M3 receptor antagonists.
