Background:

• Rising antibiotic resistance poses a significant global health threat to humans and animals.
• Antimicrobial peptides (AMPs) are emerging as a crucial alternative to conventional antibiotics.
• Cyclic AMPs, particularly macrocyclic AMPs, are gaining attention for their unique properties.

Purpose of the Study:

• To review the structures and functions of prominent cyclic natural and synthetic antimicrobial peptides.
• To highlight the potential of cyclic AMPs in combating drug-resistant bacteria.
• To provide insights into future research directions for cyclic AMPs.

Main Methods:

• Literature review of existing studies on cyclic antimicrobial peptides.
• Analysis of structural and functional data of natural and synthetic cyclic AMPs.
• Discussion of current trends and future prospects in the field.

Main Results:

• Cyclic AMPs exhibit potent antimicrobial activity against various pathogens.
• Their cyclic structures contribute to enhanced stability and efficacy.
• AMPs show a low propensity for inducing bacterial resistance.
• Both natural and synthetic cyclic AMPs represent valuable therapeutic candidates.

Conclusions:

• Cyclic antimicrobial peptides are a promising strategy to address the challenge of antibiotic resistance.
• Further research into their structures and functions can accelerate the development of novel antimicrobial agents.
• The future of cyclic AMPs in medicine is bright, offering new hope against resistant infections.
