Thalidomide is a teratogen, sedative-hypnotic with inherent anti-inflammatory properties. A selective inhibitor of tumor necrosis factor β (TNF-β ) synthesis. Binds to the E3 ubiquitin ligase complex formed between cereblon (CRBN), damaged DNA binding protein 1 (DDB1), and Cul4A inhibiting ligase activity. Inhibits FGF-induced angiogenesis. Thalidomide initiates its teratogenic effects by binding to CRBN and inhibiting the associated ubiquitin E3 ligase activity. Cell permeable.
