Abstract
The Schiff base 4-hydroxy-benzoic acid (4-diethylamino-2-hydroxy-benzylidene) hydrazide (SL) was synthesized and characterized. Its antioxidant activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging action. Being a potent antioxidant its binding ability to the transport protein bovine serum albumin (BSA) was studied using fluorescence quenching and circular dichroism (CD) studies. The binding distance has been calculated by fluorescence resonance energy transfer (FRET) to be 1.85 Å and the Stern-Volmer quenching constant has been calculated to be (3.23 ± 0.45) × 10(5) M(-1). Quantum chemical analysis was carried out for the Schiff base using DFT with B3LYP and 6-311G** and related to the experimentally obtained results. For a deeper understanding of the mechanism of the interaction, the experimental data were complemented by protein-Schiff base docking calculations using Argus Lab.
The synthesized Schiff base 4-hydroxy-benzoic acid hydrazide (SL) shows potent antioxidant activity and binding ability to bovine serum albumin (BSA), suggesting potential as a novel anti-aging agent.
