Design, Synthesis, Molecular Docking Studies of Deferasirox Derivatives of 1,2,4‐Triazole as Potential Antimicrobial Agents

Abstract

AbstractA series of deferasirox derivatives of 1,2,4‐triazole (5 a–i,6 a–g) were designed and synthesized by the ring‐opening rearrangement reaction of phenyl hydrazine or its substituents and imines, compounds 5 d–i, 6 e–g are previously unknown. Obtained derivatives were characterized by IR, 1H NMR, 13C NMR, and Mass spectral. The antibacterial activities of all compounds against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans and Aspergillus niger were experimentally evaluated. Most of them exhibited potential antimicrobial activity and promising antifungal activity. Especially, 6 f and 6 g showed the best antimicrobial activity (MIC90=0.125–2.0 μg/mL) against Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli, while compounds 6 c, 6 e showed excellent antifungal activity (MIC90=0.5–2.0 μg/mL). The molecular docking analysis further revealed that all the synthesized derivatives have shown potential binding affinities.
