Abstract
A series of novel Schiff bases derived from dipicolinic acid was synthesized and evaluated for antioxidant and iron chelating activity. In most cases Schiff bases derived from di-hydrazide showed higher antioxidant activity than the ones derived from mono-hydrazide and some of them are very promising considering the fact of being better antioxidants than the standards used in the investigation. For iron chelating activity substituents had a greater impact on the activity than mono or di-hydrazide skeleton.
Keywords: Antioxidant, dipicolinic acid, metal chelating, Schiff base, Clostridium, Bacillus, antibacterial, antifungal, antitumor, pharmaceutical
