Abstract
|
|
|
|
A number of 4-hydroxy-2H (or alkyl)-N-(3-aralkyl-2-thio-1-hydantoinyl)-1,2-benzothiazine-3-carboxamide 1,1-dioxides were synthesized through the reaction of 4-hydroxy-2H (or alkyl)-1,2-benzothiazine-3-carboxylic methyl ester 1,1-dioxide and 1-amino-2-thio-3-aralkyl-4-imidazolones in xylene. The compounds synthesized were screened for antiinflammatory effect on carrageeenin-induced edema in rat and for analgesic effect on acetic acid-induced Writhing syndrome in mice. Most compounds were inhibitors of carrageenin-induced rat foot edema and some showed significant antiinflammatory activity comparable to that of indomethacin and significant analgesic activity comparable to that of indomethacin and aspirin.
