Home Ubiquitin E3 ligase Ligand chemical - E3 Ligase inhibitor - TNF-alpha inhibitor Thalidomide For research use only.

Thalidomide

Synonyms: K17

Thalidomide was introduced as a sedative drug, immunomodulatory agent and also is investigated for treating symptoms of many cancers. Thalidomide inhibits cereblon (CRBN), a part of the cullin-4 E3 ubiquitin ligase complex CUL4-RBX1-DDB1.

Biological Activity

Thalidomide must be metabolized by the liver to form an epoxide that may be the active teratogenic metabolite. [1] 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. [2] Thalidomide exerts its inhibitory action on tumor necrosis factor alpha by enhancing mRNA degradation. [3] 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. [4] 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. [5]

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.
