Reaction of 4-amino-4,5-dihydro-1H-1,2,4-triazol-5-one with some carboxylic acid anhydrides and their antiinflammatory activity

Syntheses of a series of 3-alkyl(aryl)-4-tetrachlorophthalimido-4,5-dihydro-1H-1,2,4-triazol-5-ones and 3-alkyl(aryl)-4-(1,8-naphthalimido-4,5-dihydro)-1H-1,2,4-triazol-5-ones are described. The newly compounds were characterized by spectral and elemental analyses. Some compounds were screened for their antiinflammatory activity. All the compounds carring 1,2,4-triazole moiety showed significant antiinflammatory activity.
