Abstract: Trifluoromethanesulfonamide and salts thereof are active as antiglaucoma agent and may be administered topically to the eye. Pharmaceutical formulations of such compounds are also described.

Abstract: N-Substituted perfluoroalkanesulfonamides of the formula: ##STR1## WHEREIN R.sub.f is a perfluoroalkyl group containing one to four carbon atoms, each Y is a non-cyclic group which can contain only carbon, hydrogen, oxygen, sulfur, nitrogen and halogen and m is 1-5, provided that all of the Y groups together contain not more than about twenty carbon atoms and that at least one of the Y groups contains a heteroatom selected from oxygen, sulfur, nitrogen and halogen. Also included are salts of these compounds, compositions containing the compounds of the present invention and processes for their preparation and use. The compounds are active as herbicides and plant growth modifiers.

Abstract: Benzoylhaloalkanesulfonanilides of the general type ##SPC1##Wherein R.sub.x is a haloalkyl group having up to four carbon atoms and at least one halogen atom bonded to the alpha carbon atom or if there is no halogen bonded to said alpha carbon atom, having at least 2 halogen atoms bonded to the beta carbon atom, R is hydrogen, alkyl or alkenyl containing not more than three carbon atoms, or a pharmaceutically acceptable cation; each Y .Iadd.and Y' .Iaddend.is selected from hydroxy, halogen and alkyl, alkoxy, haloalkyl and haloalkoxy groups having up to 4 carbon atoms and n and n' are each 0-3. These compounds and their salts have valuable pharmacological activity as anti-inflammatory agents. .Iadd.
