Racemic and chiral sulfoxides as potential prodrugs of 4-pyrone COX-2 inhibitors
摘要:
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.
