Thalidomide was introduced as a sedative drug, immunomodulatory agent and also is investigated for treating symptoms of many cancers. Thalidomide inhibits an E3 ubiquitin ligase, which is a CRBN-DDB1-Cul4A complex.

Thalidomide and lenalidomide increase the protein level of WT CRBN. Plasmids expressing FS-CRBN WT were transfected into HEK293T cells and then cells were equally divided into each well of a 6-well plate. The cells were treated with thalidomide (100 µM) or lenalidomide (10 µM) for indicated time.

Murine bone marrow-derived DC (cultured for 4 d) conferred thalidomide (30 μM), PYR-41 (5 μM), or DMSO treatment prior to ovalbumin (50 μg/ml) or PBS pulse. The effects of PYR-41 and thalidomide on cross-presentation were determined by confocal microscope (b). For immunofluorescence observations, cross-presented OVA was stained with red (25-D1.16), EEA1 and Rab7 are all stained with green, and nuclei were counterstained with blue (DAPI). Original magnification, ×600.

Thalidomide must be metabolized by the liver to form an epoxide that may be the active teratogenic metabolite.  Thalidomide selectively inhibits the production of human monocyte tumor necrosis factor alpha (TNF-alpha) when human monocytes are triggered with lipopolysaccharide and other agonists in culture.  Thalidomide exerts its inhibitory action on tumor necrosis factor alpha by enhancing mRNA degradation.  Thalidomide acts directly, by inducing apoptosis or G1 growth arrest, in MM cell lines and in patient MM cells that are resistant to melphalan, doxorubicin, and dexamethasone (Dex). Thalidomide enhances the anti-MM activity of Dex and, conversely, are inhibited by interleukin 6.  Thalidomide is a potent costimulator of primary human T cells in vitro, synergizing with stimulation via the T cell receptor complex to increase interleukin 2-mediated T cell proliferation and interferon gamma production. Thalidomide also increases the primary CD8+ cytotoxic T cell response induced by allogeneic dendritic cells in the absence of CD4+ T cells. 
|In vivo||Thalidomide (200 mg/kg) results in an inhibition of the area of vascularized cornea of rabbits that ranged from 30% to 51% in three experiments with a median inhibition of 36%. |

|In vitro||DMSO||51 mg/mL (197.49 mM)|
|Ethanol||2 mg/mL (7.74 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+30% PEG 300+1% Tween 80+ddH2O (suspension)
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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.
