  Diarylspiro[2.4]heptenes as Orally Active, Highly Selective Cyclooxygenase-2 Inhibitors:  Synthesis and Structure−Activity Relationships

  摘要：

  A novel series of 5,6-diarylspiro[2.4]hept-5-enes was shown to provide highly potent and selective cyclooxygenase-2 (COX-2) inhibitors. A study of structure-activity relationships in this series suggests that 3,4-disubstituted phenyl analogs are generally more selective than 4-substituted phenyl analogs and that replacement of the methyl sulfone group on the B-phenyl ring with a sulfonamide moiety results in compounds with superior in vivo pharmacological properties, although with lower COX-2 selectivity, Several compounds have been shown to possess promising pharmacological properties in adjuvant-induced arthritis and edema analgesia models. The absence of gastrointestinal (GI) toxicity at 200 mpk of several selected compounds in rats and mice corresponds well with the weak potency for inhibition of COX-1 observed in the enzyme assay. Methyl sulfone 55 and sulfonamide 24 were shown to have superior in vivo pharmacological profiles, low GI toxicity, and good oral bioavailability and duration of action.

  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.
