title: [Beta-adrenoblocking activity and other pharmacological properties of 2-(3-amino-2-hydroxypropoxy)phenyoxymethyl isoxazole derivatives].
abstract: Some derivatives of 2-(3-amino-2-hydroxypropoxy)phenoxymethyl isoxazole possess beta- and alpha-adrenoblocking activity. 3-Methyl-4-chlor-5-(3-isopropylamino-2-hydroxypropoxy)phenoxymethyl isoxazole hydrochloride (compound OF-4452) is the most active of the compounds studied. As to the beta-adrenoblocking activity, this compound given in vivo and in vitro compares very favourably with propranolol, oxprenolol and labetalol, in particular; as regards the alpha-adrenoblocking action, it is not inferior to the latter drug. Compound OF-4452 has a partial agonist activity and nonspecific membrane-stabilizing action. It displays antifibrillatory and antiarrhythmic activity as well.
