  • Patent number: 10815275
    Abstract: Antimicrobial peptoids with improved selectivity to bacteria and a use thereof are described. Specifically, the antimicrobial peptoids have high antimicrobial activity and greatly decreased toxicity to animal cells. The antimicrobial peptoids show excellent antimicrobial activity against bacteria and exhibit low cytotoxicity to animal cells due to altered degree of folding in helical structure or altered charge characteristics. Therefore, the antimicrobial peptoids have improved selectivity to bacteria, and thus can be usefully used as antimicrobial compositions.
