Zeolite (Y‐H)‐based green synthesis, antimicrobial activity, and molecular docking studies of imidazole bearing oxydibenzene hybrid molecules

Abstract

AbstractIn this green synthesis, zeolite (Y‐H) appears to be an intriguing choice for obtaining a high yield with a shorter reaction time. In addition, we have synthesized N‐aryl‐(4‐benzylidene‐5‐oxo‐2‐phenyl‐4,5‐dihydro‐1H‐imidazol‐1‐yl)‐3‐phenoxybenzamides (4a‐i), which will be proved to be potent antimicrobial agents. The title compounds were tested against Gram‐positive, Gram‐negative, and fungal strains using the Mueller–Hinton Broth technique. N‐(4‐benzylidene‐5‐oxo‐2‐phenyl‐4,5‐dihydro‐1H‐imidazol‐1‐yl)‐3‐phenoxybenzamide (4a) (minimum inhibitory concentration [MIC] = 25 μg/mL, S. pyogenes) and N‐(4‐[4‐fluorobenzylidene]‐5‐oxo‐2‐phenyl‐4,5‐dihydro‐1H‐imidazol‐1‐yl)‐3‐phenoxybenzamide (4f) (MIC = 100 μg/mL, C. albicans, A. niger, A. clavatus) were the most effective against Gram‐positive and Gram‐negative bacteria as well as fungal strains. To understand the mechanism of action of synthesized compounds, molecular docking experiments were performed against S. aureus tyrosyl‐tRNA synthetase and C. albicans sterol 14‐α demethylase.
