Discovering a new analogue of thalidomide which may be used as a potent modulator of TNF-α production
摘要:
A new series of imide derivatives related to thalidomide were synthesized and evaluated as modulators of TNF-alpha production. These derivatives enhance TNF-a production using human leukemia HL-60 cells induced with 12-O-tetradecanoylphorbol 13-acetate (TPA), while inhibiting TNF-alpha production induced with okadaic acid (OA) in the same cell line. The diphenylmaleimide derivative 2f, was found to be the most active product, producing a strong modulation of the cytokine level. (C) 2009 Elsevier Masson SAS. All rights reserved.
A process of preparing thalidomide in which N-phthaloylglutamine or N-phthaloylisoglutamine is cyclized with N,N'-carbonyldiimidazole, characterised in that the process comprises heating said N-phthaloylglutamine or N-phthaloylisoglutamine and N,N'-carbonyldiimidazole in refluxing anhydrous tetrahydrofuran.
