A series of 2 polyaza-arylindane-1,3-diones diversely substituted on the heterocycle and the homocycle were synthetized in order to study their anti-inflammatory activity. These enaminodiketones give in alkaline medium polydent anions which can undergo, in presence of electrophilic agents, C, N or O-substitution. The Mitsunobu reaction proved to be the most useful method in attempts to gain regiospecific attack at nitrogen. Pharmacomodulation by the introduction of an ethyl group on the nitrogen of the basic molecule, eventually coupled with 5-methoxylation on the homocycle, proved to be fruitful in the pyridazinyl, pyrimidinyl and tetrazolyl series. Among the 3 most active molecules 31, 43 and 50, the second one was selected for a more detailed pharmacological study.
