Abstract
A series of N-(4-amino-2-butynyl)acetamides were synthesized and examined for their inhibitory activity on detrusor contraction and mydriatic activity as an index of anticholinergic side effect. Among those compounds synthesized, (+)-2-cyclohexyl-N-(4-dimethylamino-2-butynyl)-2-hydroxy-2-phenylacet amide hydrochloride ((+)-13b.HCl), 2-cyclohexyl-2-hydroxy-N-(4-methylamino-2-butynyl)-2-phenylacetamide+ ++ hydrochloride (13c.HCl), N-(4-dimethylamino-2-butynyl)-2,2-diphenyl-2-hydroxyacetamide hydrochloride (14a.HCl), and 2,2-diphenyl-N-(4-ethylamino-2-butynyl)-2-hydroxyacetamide hydrochloride (14b.HCl) showed equipotent inhibitory activity on detrusor contraction to oxybutynin (1) and less mydriatic activity. Further evaluation of these compounds as an agent for the treatment of overactive detrusor has been examined.
