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