  The development of novel inhibitors of tumor necrosis factor-α (TNF-α) production based on substituted [5,5]-bicyclic pyrazolones

  摘要：

  Novel substituted [5,5]-bicyclic pyrzazolones are presented as inhibitors of tumor necrosis factor-alpha (TNF-alpha) production. Many of these compounds show low nanomolar activity against lipopolysaccaride (LPS)-induced TNF-alpha production in THP-1 cells. This class of molecules was co-crystallized with mutated p38, and several analogs showed good oral bioavailability in the rat. Oral activity of these compounds in the rat iodoacetate model for osteoarthritis is discussed. (C) 2004 Elsevier Ltd. All rights reserved.

  Cyclization of various bisacylated hydrazines and pyrazolidines using DBU or sodium hydride leads to the formation of various mono-, bi- and tricyclic pyrazolone scaffolds in 41-98% yield. The convergent nature by which the precyclization intermediates are constructed allows for rapid derivatization about the pyrazolone core. (c) 2006 Elsevier Ltd. All rights reserved.
