R-(-)-Rolipram is the R-entantiomer of rolipram. This compound has been shown to strongly inhibit the catalytic activities of PDE4 (phosphodiesterase 4), which is selective for cAMP, an important secondary messenger molecule in signal transduction. Experiments have revealed that high-affinity binding sites require residues within the catalytic domains and residues flanking the N-/C-terminal to the catalytic region of amino acids. Other studies suggest that the deactivation of PDE4 has been reported to affect other cellular functions.
