Abstract
Treating wound infections caused by Gram-positive and Gram-negative bacteria, along with associated inflammation, remains challenging due to the limited therapeutic efficacy of conventional antibiotics. Leveraging the unique properties of cholic acid derivatives, such as their cationic nature, hydrophobicity, and structural adaptability, a novel aspirin-derived facile amphiphile based on cholic acid (amphiphile 1) is designed and synthesized. The investigations reveal that the amphiphile 1 functions as a bacterial membrane disruptor through interacting with key components such as lipoteichoic acid and lipopolysaccharide of bacterial membranes. It is observed that amphiphile 1 can degrade both monomicrobial and polymicrobial preformed biofilms originating from Gram-positive and Gram-negative bacteria. Animal studies demonstrate that hydrogel-based delivery of amphiphile 1 effectively mitigates bacterial infections and resolves bacterial-associated inflammation. Collectively, these findings underscore that amphiphile 1 is a putative therapeutic agent for addressing the challenges of polymicrobial infections.
期刊介绍:
Quality research. Outstanding publications. With an impact factor of 3.124 (2019), ChemMedChem is a top journal for research at the interface of chemistry, biology and medicine. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
ChemMedChem publishes primary as well as critical secondary and tertiary information from authors across and for the world. Its mission is to integrate the wide and flourishing field of medicinal and pharmaceutical sciences, ranging from drug design and discovery to drug development and delivery, from molecular modeling to combinatorial chemistry, from target validation to lead generation and ADMET studies. ChemMedChem typically covers topics on small molecules, therapeutic macromolecules, peptides, peptidomimetics, and aptamers, protein-drug conjugates, nucleic acid therapies, and beginning 2017, nanomedicine, particularly 1) targeted nanodelivery, 2) theranostic nanoparticles, and 3) nanodrugs.
