Field of application
(R)-(-)-Rolipram is a potent and cAMP-specific PDE4 inhibitor with IC50 of 0.22 uM; 2.5-fold more potent than (+)-rolipram (IC50= 2.58 uM) in inhibiting membrane-bound PDE 4.

Formula: C16H21NO3

Description: (R)-(-)-Rolipram is a potent and cAMP-specific PDE4 inhibitor with IC50 of 0.22 uM; 2.5-fold more potent than (+)-rolipram (IC50= 2.58 uM) in inhibiting membrane-bound PDE 4. in vitro: In intact eosinophils, (-)-rolipram (EC50 = 0.19 +/- 0.02 microM) was 10-fold more potent than (+)-rolipram (EC50 = 1.87 +/- 0.09 microM) in enhancing isoprenaline (10 microM)-stimulated cyclic AMP accumulation. Rolipram was a relatively weak inhibitor of partially purified pig aortic PDE IV and only slight stereospecificity was exhibited [IC50 (-)-rolipram = 1.47 +/- 0.09 microM; IC50 (+)-rolipram = 2.73 +/- 0.38 microM]. The IC50 of rolipram (racemate) of these two fractions was 492 and 79 nM, respectively. The R-(-)-enantiomer of rolipram inhibited the cAMP-phosphodiesterase activity in the latter fraction 10 times more than did S-(+)-rolipram, and the inhibition of the former fraction was less stereospecific.
