Abstract

A series of novel 2-pyridinyl-3-(4-methylsulfonyl) phenylpyridines has been synthesized and evaluated with respect to their ability to inhibit the isozymes of cyclooxygenase, COX-1, and COX-2. Optimum COX-2 activity is observed by introduction of a substituent at C5 of the central pyridine. 5-Chloro-3-(4-methylsulfonyl) phenyl-2-(2-methyl-5-pyridinyl) pyridine 33 was identified as the optimum compound in this series.
