title: A new class of acyclic 2-alkyl-1,2-diaryl (E)-olefins as selective cyclooxygenase-2 (COX-2) inhibitors.
abstract: A new class of (E)-2-alkyl-2-(4-methanesulfonylphenyl)-1-phenylethenes were designed for evaluation as selective cyclooxygense-2 (COX-2) inhibitors. The target olefins were synthesized, via a Takeda olefination reaction, followed by oxidation of the respective thiomethyl olefinic intermediate. In vitro COX-1/COX-2 inhibition studies identified (E)-2-(4-methanesulfonylphenyl)-1-phenyloct-1-ene (8d) as a potent (IC(50)=0.77 microM) and selective (Selectivity Index>130) COX-2 inhibitor.
