Product Description

Rolipram (formerly called ME-3167; ZK-62711; SB95952; the racemic mixture of R- and S-rolipram) is a novel, potent and selective phosphodiesterase PDE4 inhibitor with potential anti-inflammatory and anti-depressant activity. It inhibits PDE4A/4B/4D with IC50s of 3 nM, 130 nM and 240 nM, respectively.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
The activity of immunopurified PDE4B and PDE4D was also inhibited by the PDE4-selective inhibitor Rolipram, with IC50 values of 130 nM and 240 nM, respectively. Conversely, immunopurified PDE4A's activity was inhibited by Rolipram, albeit at a much lower IC50 of about 3 nM. Rolipram increases cAMP response element binding protein (CREB) phosphorylation in U937 cells in a dose-dependent manner, suggesting the presence of components with high and low affinity (IC50 ~1 nM and IC50 ~120 nM, respectively). With a 290 nM IC50, rolipram dose-dependently and simply and monotonically inhibits the phosphorylation of p38 MAPK when stimulated by IFN-γ [1]. All four PDE4 isoforms are inhibited by the selective PDE4 inhibitor rolipram. Rolipram inhibits the production of TNF induced by LPS in a maximal/submaximal manner and in a dose-dependent manner (IC50 of 25.9 nM). At a dosage of 2 μM, inhibitory effects were noted in J774 cells [2].
ln Vivo
Rolipram appears to have decreased the TNF mRNA and protein expression that LPS produced in WT mice's peritoneal macrophages (PM) (74% and 63% suppression of TNF mRNA and TNF protein, respectively). In line with previous findings, LPS-induced TNF production was higher in MKP-1 (-/-) mice's PM than in WT mice's PM. It's interesting to note that Rolipram's suppression of TNF mRNA and protein expression was much reduced and did not reach statistical significance in the PM of MKP-1 (-/-) mice [2]. In trained helpless rats, repeated intraperitoneal injections of Rolipram (1.25 mg/kg) can decrease the number of unsuccessful escape attempts [3].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
