In vitro evaluation of the antioxidant potential of derivatives eugenol via ABTS radical capture assay
In vitro antioxidant activity of eugenol derivatives
Abstract
Eugenol is a natural product present in different plant species, especially in the flower buds of Syzygiu Aromatum. This secondary metabolite exhibits antioxidant action, in addition to acting as an anti-inflammatory, antitumor, antibacterial, antifungal, antipyretic, anesthetic and analgesic agent. Given the biological potential of eugenol, the antioxidant activity of eugenol derivatives was evaluated. Thus, eugenol isolated from flower buds of Syzygiu aromaticum was subjected to different types of reactions such as O-alkylation. The eugenol derivatives were characterized by 1H and 13C NMR techniques. The evaluation of antioxidante activity was carried out using the ABTS radical capture assay. Six derivatives were synthesized with yields ranging from 75-92%, which exhibited low antioxidant potential compared to radical capture assays, with EC50 values from 0.085 to 0.327 mg/mL. These results motivate new studies, since the search for new antioxidant agents is extremely necessary in view of the numerous pathologies that are associated with oxidative stress.
