In-Vitro Antioxidant Activites of Novel Synthesized Copper (II) Complexes

Abstract

Introduction: The term radical is originally implied, to a portion of a molecule which cannot exist independently in nature. The Development of these radicals is driven by thermal hemolysis, high energy radiation and photolysis. Free radical attacks cause cell damage and homeostatic disruption. Targets of free radicals are all kinds of molecules in the body, such as lipids, nucleic acids and proteins are the major targets. Antioxidants are substances capable of slowing or stopping oxidation pathways that occur under the effect of reactive oxygen moieties or free atmospheric oxygen. Objectives: The main objective of the present study was to judge the advantages of the newly synthesized Copper (II) complexes in contrast to oxidative stress caused by free radicals utilizing different assays. Methods: The antioxidant ability of Cu (II) complexes were measured employing different assays including, DPPH free radical scavenging ability, ferric reducing antioxidant potential (FRAF) and total antioxidant ability assay. Results: In the DPPH scavenging potential assay, ferric reducing antioxidant potential and total antioxidant ability assay, RI-1 complex was studied to be more spectacular among the copper(II) complexes. Inhibiting ability of the complexes was RI-1 > NM-3 > AM-2 > SR-3. The Antioxidant scavenging potential was conformed as dose dependent which increases with the increase of complex concentration. Conclusion: The Copper (II) complexes were found to have high antioxidant abilities.
