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.

Articles

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
