General description

Rolipram enhances tissue protection, anatomical repair and functional recovery. It is used to treat asthma, arthritis, Huntington′s disease and multiple sclerosis. Rolipram inhibits injury-induced reductions in cyclic AMP, which is associated with acute central nervous system injury. It functions as an antidepressant, stimulates neurite outgrowth and axonal regeneration in the presence of myelin inhibitors.

Application

Rolipram has been used:
  • to investigate its effects on testicular torsion–detorsion injury(36)
  • to block the effects of phosphodiesterase-4 (PDE4)(37)
  • as a component in chemically induced long-term potentiation (cLTP) induction media(38)

Biochem/physiol Actions

Selective cAMP-specific phosphodiesterase (PDE4) inhibitor.
