Endogenous peptides that inhibit brain cyclic AMP phosphodiesterase.

These conditions include acne vulgaris, and the compound can suppress antigen-induced, lymphocytic transformation and inhibit 3'-5' cyclic AMP phosphodiesterase.

The fall in cyclic AMP means that a cyclic AMP phosphodiesterase must have been active despite the presence of IBMX (0.1 mM).

A stimulation of the breakdown of cyclic AMP by the activation of a cyclic AMP phosphodiesterase is unlikely to be responsible for the effects seen here.

Selective inhibition of rat lung cyclic AMP phosphodiesterase and cyclic GMP phosphodiesterase by cyclic nucleotides and their analogues and various drugs.
