Abstract: This invention is related to novel vasomolol, compounds of this invention have the following formula wherein R.sub.1 represents C.sub.1-4 alkyl group. ##STR1## vasomolol is an ultra short-acting and vasodilatory selective .beta..sub.1 -adrenoceptor antagonist, and is devoid of ISA.Vasomolol is an utra short acting and vasodilatory selective .beta..sub.1 -adrenoceptor antagonist, and is devoid of IA. The ultra short-acting and vsodilatory .beta..sub.1 -adrenoceptor blocking activities of vasomolol-a guaiacoxypropanolamine derivative of vanillic acid ethyl ester--were studied. Vasomolol (0.5, 1.0, 3.0 mg/kg, I.v.) produced a dose-dependent bradycardia rsponse, and particularly a hypotensive action with an ultra short-acting property in pentobarbital-anesthetized normotensive rats. Vasomolol's steady-state of .beta.-blockade was attained within 10 min after initiation of an infuson and a rapid recovery from blockade took place after termination of the infusion. In isolated rat aorta, vasomolol (10.sup.-6 M-10.
