Cyclic adenosine monophosphate and cardiac contractility.
• This review examines critically the evidence bearing on the hypothesis that the positive inotropic effects of catecholamines are mediated by intracellular cyclic adenosine monophosphate (cyclic AMP). The review is selective in several respects. For example, it does not contain extensive discussions about the biochemical actions of cyclic AMP, the enzymes regulating its synthesis and degradati...

متن کاملDissociations between changes in myocardial cyclic adenosine monophosphate and contractility.
The relationship between changes in the myocardial concentration of adenosine 3':5'-cyclic monophosphate (cyclic AMP) and cardiac contractility was studied in guinea pig and rat myocardium. When isolated perfused guinea pig heart were perfused with 10-5-M papaverine, a potent inhibitor of cyclic AMP phosphodiesterase activity, myocardial cyclic AMP concentration increased significantly from 1.7...

An abstract of this work appeared in 1970 Abstracts, The American Society of Nephrology. Received for publication 27 October 1970 and in revised form 28 January 1971. similar to the effect of renal arterial infusion of isoproterenol. The results suggest that synthesis of cyclic AMP in proximal renal tubule cells in response to stimulation of beta adrenergic or other receptors can mediate a decr...
