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

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

Cochlear afferent synapses connecting inner hair cells to spiral ganglion neurons are susceptible to excitotoxic trauma on exposure to loud sound, resulting in a noise-induced cochlear synaptopathy (NICS). Here we assessed the ability of cyclic AMP-dependent protein kinase (PKA) signaling
