A series of novel 2-pyridinyl-3-(4-methylsulfonyl)phenylpyridines has
been synthesized and evaluated with respect to their ability to inhibi
t the isozymes of cyclooxygenase, COX-I, and COX-2. Optimum COX-2 acti
vity is observed by introduction of a substituent at C5 of the central
pyridine. ylsulfonyl)phenyl-2-(2-methyl-5-pyridinyl)pyridine 33 was i
dentified as the optimum compound in this series. (C) 1998 Published b
