Abstract

This invention relates to novel 3-substituted-2-oxindole derivatives which are inhibitors of prostaglandin H.sub.2 synthase, 5-lipoxygenase and interleukin-1 biosynthesis. The compounds of the invention are useful as inhibitors of prostaglandin H.sub.2 synthase and interleukin-1 biosynthesis, per se, and as analgesic, antiinflammatory and antiarthritic agents in the treatment of chronic inflammatory diseases. This invention also relates to pharmaceutical compositions comprising said 3-substituted-2-oxindole derivatives; to methods of inhibiting prostaglandin H.sub.2 synthase and biosynthesis of interleukin-1; and to treating chronic inflammatory diseases in a mammal with said compounds. Further, this invention relates to certain novel carboxylic acids useful as intermediates in the preparation of the 3-substituted-2-oxindole derivatives of this invention and to a process for the preparation of the 3-substituted-2-oxindole derivatives.
