      (S)-(+)-Rolipram is a PDE4-inhibitor and an anti-inflammatory agent, less potent than its R enantiomer.; Target: PDE4B; PDE4D; Rolipram, a selective inhibitor of the cyclic AMP-specific phosphodiesterase (PDE IV). MedChem Express HY-B0392
      (S)-(+)-Rolipram is a PDE4-inhibitor and an anti-inflammatory agent, less potent than its R enantiomer.;Target: PDE4B; PDE4DRolipram, a selective inhibitor of the cyclic AMP-specific phosphodiesterase (PDE IV). Rolipram did not inhibit 5-lipoxygenase activity but did inhibit human monocyte production of leukotriene B4 (LTB4, IC50 3.5 microM). Rolipram inhibited arachidonic acid-induced inflammation in the mouse, while the low Km-cyclic-GMP PDE inhibitor. Rolipram had a modest effect on LTB4 production in the mouse, but markedly reduced LTB4-induced PMN infiltration [1]. In humans and animals rolipram produces thereby a variety of biological effects. These effects include attenuation of endogenous depression and inflammation in the central nervous system (CNS), both effects are of potential clinical relevance [2]. MedChem Express HY-B0392
