1-Isopropylamino-3-(4-indanoxy)-2-propanol HC1: a potent beta-adrenoreceptor antagonist

British Journal of Pharmacology
B Levy, M Wasserman


1. The beta-adrenoceptor blocking activity of 1-isopropylamino-3-(4-indanoxy)-2-propanol HCl (USVC 6524) was determined in the anaesthetized dog, the isolated rat uterus and the isolated guinea-pig tracheal strip.2. USVC 6524 inhibited the positive inotropic, positive chronotropic and vasodilator responses to isoprenaline in the dog in a dose of 10 mug/kg and higher. On the basis of comparative pA(2) values, USVC 6524 is approximately 10 times more potent as a beta-adrenoceptor antagonist than propranolol.3. Cardiac depressant effects produced by USVC 6524 were relatively mild and occurred only after the onset of a strong beta-adrenoceptor blockade.4. USVC 6524 also blocked beta-adrenoceptors in the isolated rat uterus and guinea-pig tracheal spiral strip.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.


Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
