A class of 1,3,5-substituted pyrazoles is described for the treatment of inflammation, including treatment of pain and disorders such as arthritis. Compounds of particular interest are of formula (I) wherein R1 is lower alkylsulfonyl or sulfamyl; wherein R2 is aryl or heteroaryl; wherein R2 is optionally substituted at a substitutable position with one or more radicals selected from halo, lower alkoxy, lower alkyl, nitro, lower alkylthio, amino, lower haloalkyl, hydroxyl, carboxyl, N-monoalkylamino, N,N-dialkylamino, cyano, alkoxycarbonyl and acylamino; wherein R3 is selected from hydrido, lower alkyl, lower haloalkyl, cyano, carboxyl, alkoxycarbonyl, amino, acyl, acylamino, halo and alkylsulfonylamino; wherein R4 is aryl or heteroaryl; wherein R4 is optionally substituted at a substitutable postion with one or more radicals selected from halo, lower alkoxy, lower alkyl, nitro, lower alkylthio, amino, lower haloalkyl, hydroxyl, carboxyl, N-monoalkylamino, N,Ndialkylamino, cyano, alkoxycarbonyl and acylamino; provided at least one or R2 and R4 cannot be phenyl or substituted triazole, when R1 is sulfamyl; further provided R2 cannot be 4-methoxyphenyl or 4-methylphenyl when R4 is 4methoxyphenyl or 4-methylphenyl, and when R1 is sulfamyl; and further provided that R2 cannot be tetrazole when R4 is fluorophenyl, and when R1 is methylsulfonyl; or a pharmaceutically-acceptable salt thereof.
