Abstract
The cyclic nucleotide analog, 8-(benzylthio)-N6-n-butyladenosine cyclic 3'',5''-phosphate (SQ 80122) increases contractile force of excised cat right ventricular papillary muscle and stimulates myocardial contractility in the anesthetized dog. The inotropic action of this compound is independent of catecholamines and stimulation of .beta.-adrenergic receptors in the heart.
