Experimental study of dibutyryl cyclic AMP; its metabolic effects observed in anesthetized human subjects.

Metabolic effects of N6,O2-dibutyryl adenosine 3',5'-monophosphate (DBcAMP) were studied in 10 anesthetized patients who were divided at random into two groups each consisting of 5 patients. DBcAMP dissolved in 200 ml of physiological saline was administered intravenously at a rate of 10 mg/min for 20 min in one group and 20 mg/min for 20 min in the other group. DBcAMP infusion at either rate increased levels of blood glucose, immunoreactive plasma insulin, blood pyruvate and blood redox-potential while it reduced levels of glycerol, non-esterified fatty acid and inorganic phosphate. These findings suggest that 200 and 400 mg of DBcAMP stimulates glycogenolysis and glycolysis but inhibits lipolysis in man.
