A Novel Heterocyclic Schiff Base: Electrochemical and Antioxidant Investigation
Abstract
Electrochemical and AA study of a new heterocyclic Schiff base (L1) was herein carried out for the first time.Electrochemical results and AA tests were performed using PDP, in vitro, by ABTS, C40H56/C18H32O2, DPPH and FRAP, respectively.IE(%) of this compound against corrosion of MS, immersed in a KOH simulated concrete solution (pH of 13.5), with 0.8 M Cl -, was investigated.Electrochemical results showed that L1 was a good CI, even at low Ct (from 10 -3 to 10 -6 M; τinhib > 98%), the best scavenger in DPPH and ABTS (IC50: 0.022 ± 0.00 and 0.003 ± 7.92E-05 μg/mL, respectively), and the most active in C40H56/C18H32O2 test, with a an IE(%) of 80.22 ± 1.58%.L1 exhibited a significant reducing capacity (A0.5: 0.008 ± 0.00 mg/mL) analogous to that obtained for Trolox (A0.5: 0.008 ± 9.14 05 mg/mL).This study demonstrated L1 good IE(%) and AA.
