CAS No. 19171-19-8
Pomalidomide (CC-4047) inhibits LPS-induced TNF-α release with IC50 of 13 nM in PBMCs. Pomalidomide can be utilized in PROTAC as a ligand for targeting E3 ligase and inhibiting the E3 ligase protein cereblon (CRBN). Pomalidomide promotes apoptosis and cell cycle arrest.

|Description||Pomalidomide (CC-4047) inhibits LPS-induced TNF-α release with IC50 of 13 nM in PBMCs. Pomalidomide can be utilized in PROTAC as a ligand for targeting E3 ligase and inhibiting the E3 ligase protein cereblon (CRBN). Pomalidomide promotes apoptosis and cell cycle arrest.|
|Features||A derivative of thalidomide and up to 10,000 times more potent than thalidomide.|
Pomalidomide inhibits lipopolysaccharide (LPS) stimulated TNF-alpha release in human PBMC and in human whole blood with IC50 values of 13 nM and 25 nM, respectively.  Pomalidomide inhibits the growth of T regulatory cells which is stimulated by IL-2 with an IC50 of ~1 μM.  Treatment with Pomalidomide (6.4 nM-10 μM) increases the production of IL-2 in human peripheral blood T cells, and is slightly more potent in the CD4+ subset than in the CD8+ subset. Pomalidomide is significantly more potent than CC-5013 at elevating IL-2, IL-5, and IL-10 levels, but only slightly more potent than CC-5013 at elevating IFN-γ levels. Pomalidomide enhances SEE and Raji cells induced AP-1 transcriptional activity in Jurkat cells in a dose-dependent manner, with a maximal enhancement of 4-fold at 1 μM.  Exposure of Raji cells to various concentrations of Pomalidomide (2.5-40 μg/mL) for 48 hours leads to a significant decrease in cell proliferation and DNA synthesis. There is a reduction of ~40% compared to vehicle-treated controls. 
Pomalidomide enhances the antitumor effect of rituximab against B-cell lymphomas in severe combined immunodeficient mice. Administration of Pomalidomide in combination with rituximab, gives the mice a median survival period of 74 days compared with 58 days of CC5013/rituximab treatment and 45 days of rituximab nonotherapy. The synergistic effect of Pomalidomide and rituximab can be completely abrogated by depletion of NK cells, supporting the proposal that NK cell expansion is one mechanism by which Pomalidomide may augment rituximab antitumor activity. 
Inhibition of TNF-α synthesis:TNF-α inhibitory activity is measured in lipopolysacharide (LPS) stimulated PBMC. Pomalidomide is added to human PBMCs 1 hour prior to the addition of LPS (1 μg/mL) and incubation continued for an additional 18-20 hours. Supernatants are then harvested, and the concentration of TNF-α in the supernatants is determined by ELISA. The concentration of Pomalidomide that inhibits TNF- production by 50% (IC50) is calculated by nonlinear regression analysis. The human whole blood TNF- inhibition assay is run in a similar fashion to the PBMC assay except that heparinized fresh human whole blood is plated directly into microtiter plates.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
