title: Terferol, an inhibitor of cyclic adenosine 3',5'-monophosphate phosphodiesterase. I. Isolation and characterization.
abstract: Terferol, a new inhibitor of cyclic adenosine 3',5'-monophosphate phosphodiesterase (EC 3.1.4.17, cAMP-PDE), was isolated from the cultured broth of Streptomyces showdoensis SANK 65080. It was found to have the molecular formula C19H16O3 and to possess inhibitory activity not only against cAMP-PDE but also against cyclic guanosine 3',5'-monophosphate phosphodiesterase (cGMP-PDE) from various rat tissues. The terferol concentration required for 50% inhibition of cAMP-PDE was 0.82 microM.
