Abstract:A class of pyrazolyl benzenesulfonamide compounds is described for use in treating inflammation and inflammation-related disorders. Compounds of particular interest are defined by Formula II: ##STR1## wherein R.sup.2 is selected from hydrido, alkyl, haloalkyl, alkoxycarbonyl, cyano, cyanoalkyl, carboxyl, aminocarbonyl, alkylaminocarbonyl, cycloalkylaminocarbonyl, arylaminocarbonyl, carboxyalkylaminocarbonyl, carboxyalkyl, aralkoxycarbonylalkylaminocarbonyl, aminocarbonylalkyl, alkoxycarbonylcyanoalkenyl and hydroxyalkyl; wherein R.sup.3 is selected from hydrido, alkyl, cyano, hydroxyalkyl, cycloalkyl, alkylsulfonyl and halo; and wherein R.sup.4 is selected from aralkenyl, aryl, cycloalkyl, cycloalkenyl and heterocyclic; wherein R.sup.4 is optionally substituted at a substitutable position with one or more radicals selected from halo, alkylthio, alkylsulfonyl, cyano, nitro, haloalkyl, alkyl, hydroxyl, alkenyl, hydroxyalkyl, carboxyl, cycloalkyl, alkylamino, dialkylamino, alkoxycarbonyl, aminocarbonyl, alkoxy, haloalkoxy, sulfamyl, heterocyclic and amino; provided R.sup.2 and R.sup.3 are not both hydrido; further provided that R.sup.2 is not carboxyl or methyl when R.sup.3 is hydrido and when R.sup.4 is phenyl; further provided that R.sup.4 is not triazolyl when R.sup.2 is methyl; further provided that R.sup.4 is not aralkenyl when R.sup.2 is carboxyl, aminocarbonyl or ethoxycarbonyl; further provided that R.sup.4 is not phenyl when R.sup.2 is methyl and R.sup.3 is carboxyl; and further provided that R.sup.4 is not unsubstituted thienyl when R.sup.2 is trifluoromethyl; or a pharmaceutically-acceptable salt thereof.
