Abstract

Chlorpropamide and phenformin inhibited (Na+ - K+)-ATPase and stimulated a high affinity cyclic AMP-phosphodiesterase of isolated liver plasma membrane when tested in vitro. In addition, the two drugs decreased the intracellular cyclic AMP content of isolated hepatocytes without being effective on plasma membrane-bound adenylate cyclase. The results suggest that the plasma membrane plays an important role in the mechanism of action of the two hypoglycemic drugs, but do not exclude the presence of intracellular targets.
