A class of compounds is described for treating inflammation and inflammation-related disorders. Compounds of particular interest are defined by formula (I), wherein R1 is selected from lower alkyl, lower haloalkyl, lower hydroxyalkyl, lower alkoxyalkyl, lower alkenyloxyalkyl, mercapto, lower alkylcarbonyl, lower haloalkylcarbonyl, phenylcarbonyl, lower aralkylcarbonyl, lower aralkenyl, lower aryloxyalkyl, lower aralkyloxyalkyl, lower arylsulfonyl, lower aralkylsulfonyl, lower arylthioalkyl, lower heteroarylalkylthioalkyl, and heteroaryl selected from 2-thienyl, 2-furyl, 3-furyl, 2-pyridyl, 4-pyridyl and 2-benzofuryl; wherein R?2 and R3¿ are independently selected from heteroaryl, cycloalkyl and aryl, wherein the heteroaryl, cycloalkyl and aryl radicals are substituted at a substitutable position with one or more radicals selected from hydrido, halo, lower alkylthio, lower alkylsulfinyl, lower alkylsulfonyl, aminosulfonyl, lower alkyl, cyano, carboxyl, lower alkoxycarbonyl, lower haloalkyl, hydroxyl, lower alkoxy, lower hydroxyalkyl, lower alkoxyalkyl, lower haloalkoxy, amino, lower alkylamino, phenylamino and nitro; and wherein R4 is selected from hydrido, lower alkyl and acyl; or a pharmaceutically acceptable salt thereof. |
