  Synthesis and Biological Evaluation of 2-Phenylpyran-4-ones:  A New Class of Orally Active Cyclooxygenase-2 Inhibitors

  摘要：

  A series of 2-phenylpyran-4-ones were prepared and evaluated for their ability to inhibit cyclooxygenase-2 (COX-2). Extensive structure-activity relationship work was carried out within this series, and a number of potent and selective COX-2 inhibitors were identified. Compounds having a p-methylsulfone group at the 2-phenyl ring showed the best COX-2 inhibitory activity. The introduction of a substituted phenoxy ring at position 3 enhanced both the in vitro and in vivo activity within the series. A selected group of 3-phenoxypyran-4-ones exhibited excellent activity in an experimental model of pyresis. The in vivo antiinflammatory activity of these compounds was confirmed with the evaluation of their antiarthritic and analgesic effectiveness. Moreover, their pharmacokinetic profile in rats is compatible with a once a day administration by oral route in humans. Within this novel series, compounds 21, 31, 34, and 35 have been selected for further preclinical. and clinical evaluation.

• Racemic and chiral sulfoxides as potential prodrugs of 4-pyrone COX-2 inhibitors

  The preparation of the sulfoxide analogues 7, 8, and 9 and their enantiomerically pure forms is discussed as well as their ability to act as prodrugs of the potent and selective sulfone-containing COX-2 inhibitors 1, 2, and 3. Sulfoxide derivatives 7 and 9 were shown to be rapidly transformed in vivo into the corresponding sulfone derivatives I and 3, after oral administration to rats. (c) 2006 Elsevier Ltd.
