General description

A cell-permeable, selective inhibitor of cAMP-specific phosphodiesterase (PDE IV; IC50 = 800 nM). A rolipram-insensitive PDE IV subtype is also known to exist. Also inhibits NF-κB and NFAT activation in Jurkat and primary T cells.
Cell permeable, selective competitive inhibitor of cAMP-specific phosphodiesterase IV (IC50 = 800 nM). Rolipram does not inhibit PDE I or PDE II, even at concentrations as high as 100 µM. It is only a weak inhibitor of PDE III (IC50 = 100 µM). A rolipram-insensitive phosphodiesterase IV subtype is also known to exist.

Biochem/physiol Actions

Cell permeable: yes
Primary Target
PDE IV
Product does not compete with ATP.
Reversible: no
Target IC50: 800 nM against cAMP-specific phosphodiesterase (PDE IV)

Warning

Toxicity: Irritant (B)

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). DMSO stock solutions are stable for up to 6 months at -20°C.

Overexpression of forkhead transcription factor FOXC2 in white adipose tissue (WAT) leads to a lean phenotype resistant to diet-induced obesity. This is due, in part, to enhanced catecholamine-induced cAMP-PKA signaling in FOXC2 transgenic mice. Here we show that rolipram treatment

Angiotensin type-1 receptors (AT(1) receptors) mediate various physiological actions of angiotensin (Ang II) via multiple-signal transduction pathways (1). In addition to the phospholipase C pathway and dihydropyridine-sensitive voltage-dependent calcium channels, AT(1) receptors can couple to inhibition of adenylate cyclase via
