Chemical Innovations of Antimicrobial Polymers for Combating Antimicrobial Resistance

Area of Science:

• Polymer Science
• Microbiology
• Infectious Diseases

Background:

• The escalating global crisis of antimicrobial resistance (AMR) necessitates novel therapeutic approaches beyond conventional antibiotics.
• Antimicrobial polymers present a viable alternative due to their membrane-disrupting or multi-target mechanisms, which circumvent resistance development.

Purpose of the Study:

• To review recent advancements in the design and synthesis of antimicrobial polymers.
• To explore their applications in treating systemic and topical infections.
• To identify challenges hindering clinical translation and suggest future research directions.

Main Methods:

• Review of current literature on antimicrobial polymer design, synthesis, and application.
• Analysis of chemical motifs and structural derivatives of antimicrobial polymers.
• Evaluation of challenges in clinical translation for systemic and topical infections.

Main Results:

• Antimicrobial polymers demonstrate efficacy through various mechanisms, including membrane disruption and targeting multiple microbial functions.
• Successful applications in combating both systemic and topical infections are emerging.
• Key challenges include achieving adequate dosage, bioavailability, stability for systemic use, and biofilm dispersal for topical treatments.

Conclusions:

• Antimicrobial polymers hold significant potential as next-generation therapeutics against multidrug-resistant pathogens.
• Addressing challenges in dosage, delivery, and biofilm penetration is crucial for clinical success.
• Further research can optimize antimicrobial polymer development for improved treatment outcomes.
