Modification strategies for improving anti-enzymatic stability of antimicrobial peptides
As antibiotic resistance becomes increasingly concerning,antimicrobial peptides,as a new type of antibiotic alternative,have attracted more attention.However,the low enzymatic stability of antimicrobial peptides severely limits their clinical applications.To address this issue,researchers have developed various structural modification strategies,including the introduction of unnatural amino acids,peptide chain cyclization and chemical group modification.This article reviews the basic principles and cases of the above modification strategies analyzes the advantages and disadvantages of different modification strategies and recommends ways these strategies can be optimized.In addition,this article predicts the developments of and potential challenges to strategies for enhancing enzymatic stability of antimicrobial peptides in the hope of providing references for subsequent research and development of antimicrobial peptides.
