tcsc3246 (R) - (-) -Rolipram

(R)-(-)-Rolipram is the R-enantiomer of Rolipram. Rolipram is a selective inhibitor of phosphodiesterases PDE4 with IC₅₀ of 3 nM, 130 nM and 240 nM for PDE4A, PDE4B, and PDE4D, respectively.

In Vitro: The increase of cAMP synthesis with the adenylate cyclase activator forskolin or the decrease of cAMP hydrolysis by the phosphodiesterase inhibitors Isobutylmethylxanthine (IBMX) and (R)-(-)-Rolipram (MedChem Express) suppresses caspase-1 cleavage and IL-1β secretion in a dose-dependent manner^[1].
