Abstract
In this study, 3-alkyl(aryl)-4-(3-methoxy-4-isobutyryloxy)benzylideneamino-4,5-dihydro-1H-1,2,4-triazol-5-ones (1) were treated with morpholine in the presence of formaldehyde according to the Mannich reaction to synthesize five novel 1-(morpholine-4-yl-methyl)-3-alkyl(aryl)-4-(3-methoxy-4-isobutyryloxy)benzylideneamino-4,5-dihydro-1 H -1,2,4-triazol-5-ones (2). In addition, the antioxidant properties of compounds 2 were analyzed and evaluated using three antioxidant assays, including reducing power, free radical scavenging and metal chelating activity. For the measurement of the reductive ability, Fe 3+ -Fe 2+ transformation was investigated in the presence of compound using by the method of Oyaizu (1986). The hydrogen atoms or electrons donation ability of the synthesized compound was measured by DPPH . using the method of Blois (1958 ). The chelating effect of ferrous ions by the compound was determined according to the method of Dinis, Madeira & Almeida (1994 ). BHT, BHA, EDTA and α-tocopherol were used as reference antioxidant compounds.
