Celgene Corporation is an American biotechnology company that manufactures drug therapies for cancer and inflammatory disorders. It is incorporated in Delaware and headquartered in Summit, New Jersey. The company's major products are Thalomid , which is approved for the acute treatment of the cutaneous manifestations of moderate to severe erythema nodosum leprosum , as well as in combination with dexamethasone for patients with newly diagnosed multiple myeloma, and Revlimid , for which the company has received FDA and EMA approval in combination with dexamethasone for the treatment of multiple myeloma patients who have received at least one prior therapy. Revlimid is also approved in the United States for the treatment of patients with transfusion-dependent anemia due to Low- or Intermediate-1-risk Myelodysplastic syndromes associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities. Both Thalomid and Revlimid are sold through proprietary risk-management distribution programs to ensure safe and appropriate use of these pharmaceuticals. Vidaza is approved for the treatment of patients with MDS. Celgene also receives royalties from Novartis Pharma AG on sales of the entire Ritalin family of drugs, which are widely used to treat Attention Deficit Hyperactivity Disorder .Celgene Cellular Therapeutics, a subsidiary, is a public cord blood bank.

The Cul4-Rbx1-DDB1-Cereblon E3 ubiquitin ligase complex is the target of thalidomide, lenalidomide and pomalidomide, therapeutically important drugs for multiple myeloma and other B-cell malignancies. These drugs directly bind Cereblon (CRBN) and promote the recruitment of substrates Ikaros (IKZF1) and Aiolos (IKZF3) to the E3 complex, thus leading to substrate ubiquitination and degradation. Here we present the crystal structure of human CRBN bound to DDB1 and the drug lenalidomide. A hydrophobic pocket in the thalidomide-binding domain (TBD) of CRBN accommodates the glutarimide moiety of lenalidomide, whereas the isoindolinone ring is exposed to solvent. We also solved the structures of the mouse TBD in the apo state and with thalidomide or pomalidomide. Site-directed mutagenesis in lentiviral-expression myeloma models showed that key drug-binding residues are critical for antiproliferative effects. Source

The present invention provides compounds, compositions thereof, and methods of using the same.

Substituted 2-(2,6-dioxopiperidin-3-yl)phthalimides and 1-oxo-2-(2,6-dioxopiperidin-3-yl)isoindolines are disclosed. The compounds are useful, for example, in reducing the levels of TNF in a mammal.

The present invention provides a salt form and compositions thereof, which are useful as an inhibitor of EGFR kinases and which exhibits desirable characteristics for the same.

With an aim to provide a novel factor inducing proliferation of neural stem cells and differentiation of these cells into nerve cells, a pharmaceutical composition comprising 1) CRBN, 2) a nucleic acid encoding CRBN, or 3) a stem cell or a neural progenitor cell in which CRBN is expressed, a method including administering the pharmaceutical composition to a non-human animal and inducing proliferation of neural stem cells or neural progenitor cells of the non-human animal and differentiation of these cells into nerve cells, and a method for screening for a therapeutic drug for a disease of cerebral cortex or a surgical injury of cerebral cortex, using CRBN, are provided.
