title: 1-[4-(Methylsulfonyl)phenyl]-5-phenyl-1H-pyrazole derivatives.
abstract: Three related compounds containing a pyrazole moiety with vicinal phenyl rings featuring a methylsulfonyl substituent are described, namely 3-methyl-1-[4-(methylsulfonyl)phenyl]-5-phenyl-1H-pyrazole, C17H16N2O2S, ethyl 1-[4-(methylsulfonyl)phenyl]-5-phenyl-1H-pyrazole-3-carboxylate, C19H18N2O4S, and 1-[4-(methylsulfonyl)phenyl]-3-[3-(morpholino)phenoxymethyl]-5-phenyl-1H-pyrazole, C27H27N3O4S. The design of these compounds was based on celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, in order to study the influence of various substituents on COX-2 and 5-lipoxygenase (5-LOX) inhibition.
