RÉSUMÉ
We report the synthesis, characterization, biological evaluation and quantitative structure-activity relationship of some Schiff base esters as promising new antitumor, antioxidant and anti-inflammatory agents. The Schiff base esters were synthesized by two synthetic routes using variably substituted hydroxy benzaldehydes with para amino phenol in appreciable yields. All the newly synthesized esters have been characterized by [1]H-NMR, [13]C-NMR, FT-IR techniques and elemental analysis. The synthesized esters were examined for antioxidant, antitumor and anti-inflammatory potentials through different bioassays and quantitative structure-activity relationship was studied. Bioassays showed encouraging results and indicated that some of these title compounds may have potential for further pharmacological investigations
