Synthesis and biological evaluation of 1,3,4-triaryl-3-pyrrolin-2-ones, a new class of selective cyclooxygenase-2 inhibitors.

The synthesis and structure activity relationships (SAR) of a series of novel selective COX-2 inhibitors are reported. The results show that some of the 1,3,4-triaryl-3-pyrrolin-2-ones 1 are more potent as COX-2 inhibitors than celecoxib, and that lactam Id has the same selectivity.
