Oxidative Stress-Generating Antimicrobials, a Novel Strategy to Overcome Antibacterial Resistance

Area of Science:

• Microbiology and Infectious Diseases
• Drug Discovery and Development
• Oxidative Stress Biology

Background:

• Antimicrobial resistance (AMR) is a critical global health challenge, necessitating urgent development of novel therapeutic strategies.
• Oxidative stress induction is an emerging approach to overcome bacterial resistance by disrupting pathogen redox homeostasis.
• Repurposing existing antimicrobials and discovering new natural products are key to combating recalcitrant bacterial infections.

Purpose of the Study:

• To review the current landscape of oxidative stress-generating compounds as antimicrobial agents.
• To highlight novel natural products (plant and bacterial metabolites) with antibacterial activity via oxidative stress.
• To focus on the potential of these compounds against intracellular bacterial pathogens.

Main Methods:

• Literature review of recent research on oxidative stress and antimicrobial activity.
• Analysis of studies identifying novel plant and bacterial secondary metabolites.
• Evaluation of compounds targeting bacterial redox defenses.

Main Results:

• Oxidative stress-inducing agents show promise in overcoming antimicrobial resistance.
• Several novel plant and bacterial metabolites have been identified with potent antibacterial mechanisms involving oxidative stress.
• These compounds demonstrate potential for treating infections caused by challenging intracellular pathogens.

Conclusions:

• Targeting bacterial redox balance with oxidative stress-generating compounds is a viable strategy against AMR.
• Novel natural products offer a promising source for developing new antibiotherapeutics, particularly for intracellular infections.
• Further research into these compounds could lead to effective combinatorial therapies for resistant bacterial infections.
