  2,3-Diarylcyclopentenones as Orally Active, Highly Selective Cyclooxygenase-2 Inhibitors

  摘要：

  Cyclopentenones containing a 4-(methylsulfonyl)phenyl group in the 3-position and a phenyl ring in the 2-position are selective inhibitors of cyclooxygenase-2 (COX-2). The selectivity for COX-2 over COX-1 is dramatically improved by substituting the 2-phenyl group with halogens in the meta position or by replacing the phenyl ring with a 2- or 3-pyridyl ring. Thus the 3,5-difluorophenyl derivative 7 (L1776,967) and the 3-pyridyl derivative 13 (L-784,506) are particularly interesting as potential antiinflammatory agents with reduced side-effect profiles. Both exhibit good oral bioavailability and are potent in standard models of pain, fever, and inflammation yet have a much reduced effect on the GI integrity of rats compared to standard nonsteroidal antiflammatory drugs.

  2-(3',5'-Difluorophenyl)-3-(4'-methylsulfonylphenyl)cyclopent-2-enone (1) displays high selectivity and potency against COX-2. Three efficient syntheses of this diarylcyclopentenone are described. The first approach employs a Suzuki coupling reaction as the key step while the second synthesis features an intramolecular Friedel-Crafts acylation. The third, and preferred route to this compound involves a sequential malonate alkylation and acylation and ring-closure sequence. (C) 1999 Elsevier Science Ltd. All rights reserved.
