Abstract:
Proteins are essential to the survival and pathogenicity of microorganisms, serving as structural components, enzymes, and regulatory elements. Schiff bases, organic compounds formed by the condensation of primary amines with carbonyl compounds, have emerged as promising antimicrobial agents due to their ability to disrupt microbial protein integrity. This study investigates the multifaceted interactions between Schiff bases and microbial proteins, revealing key mechanistic insights such as membrane disruption, enzyme inhibition, metal chelation, and Reactive Oxygen Species (ROS) generation. Notably, Schiff bases demonstrate potent activity against multidrug-resistant strains, including Staphylococcus aureus, Escherichia coli, and Candida albicans, and exhibit synergistic effects when combined with conventional antibiotics. Proteomic analysis highlights their impact on survival-associated and pathogenicity-related proteins, including chaperones, efflux pumps, and virulence factors. These findings underscore the novelty of targeting microbial proteomes and stress-response pathways, positioning Schiff bases as versatile candidates for next-generation antimicrobial therapies.
