Synthesis and biological evaluation of ibuprofen/o-vanillin Schiff base complexes with anti-inflammatory, anti-proliferative and anti-SARS-COV-19 activities

2026Open accessSohag University

Abstract

This study presents the synthesis and comprehensive characterization of four novel metal-complexes formed from the reaction of copper(II), nickel(II), zinc(II), and vanadium(IV) salts with the bidentate ibuprofen Schiff base ligand (HL) in 1:1 metal-to-ligand ratio. The copper complex shows the highest antibacterial and cytotoxicity efficiency, in addition to a strong binding interactions with DNA. The in-vitro anti-inflammatory and anti-COVID-19 potencies of HL and its complexes were assessed, ranking them as: CuL > NiL > ZnL > VOL > HL.
