Evaluation of metal-based antimicrobial compounds for the treatment of bacterial pathogens

Area of Science:

• Medicinal Chemistry
• Microbiology
• Materials Science

Background:

• Antimicrobial resistance (AMR) poses a significant global health challenge, reducing antibiotic efficacy and increasing mortality.
• The pipeline for novel antibiotics with new mechanisms of action is insufficient to combat rising AMR.
• Metals, historically used for antibacterial purposes, were largely superseded by antibiotics but show renewed potential.

Purpose of the Study:

• To review the antibacterial activity and mechanisms of action of metal-based complexes.
• To evaluate the potential of metal-based agents for systemic use against resistant bacteria.
• To identify limitations and future directions for metal-based antibacterial therapies.

Main Methods:

• Literature review of metal-based complexes with reported antibacterial activity.
• Analysis of studies detailing the mode of action of these compounds.
• Assessment of preclinical and clinical data regarding systemic application and toxicity.

Main Results:

• Metal-based complexes exhibit diverse antibacterial activities through novel mechanisms.
• Some metal compounds, like auranofin, have established therapeutic uses, indicating potential for antibacterial applications.
• Challenges remain regarding toxicity, delivery, and spectrum of activity for systemic use.

Conclusions:

• Metal-based compounds represent a promising strategy to overcome conventional antibiotic resistance.
• Further research is needed to optimize efficacy, safety, and delivery for clinical translation.
• Metal-based agents could offer a vital alternative for treating infections caused by multidrug-resistant bacteria.
