The effect of CGP 20712A (1–100 μM) on β-adrenoceptor agonist-induced relaxation in rat thoracic aortic rings preconstricted with noradrenaline (1 μM). Results are expressed as percentage relaxation of tone induced by noradrenaline. Values are mean±s.e.mean of n observations. (a) Effect of CGP 20712A (1–100 μM) on relaxation induced by isoprenaline (in the presence of 1 μM propranolol) (n=4–5). (b) Effect of CGP 20712A (1–100 μM) on relaxation induced by CGP 12177A (n=4).
