  • Publication number: 20240368221
    Abstract: The present invention relates to an Impatiens balsamina-derived anti-bacterial peptide and an anti-bacterial composition comprising same. Specifically, six types of peptide derivatives were prepared on the basis of the sequence of a conventional Impatiens balsamina-derived peptide Ib-AMP4 known to have anti-fungal activity, and a peptide derivative exhibiting anti-bacterial and anti fungal activity better than that of Ib-AMP4 and having weak cytotoxicity and hemolytic properties has been identified, and thus the peptide derivative, which is an Impatiens balsamina-derived anti-bacterial peptide, can be used, in the fields of medicine, cosmetics and food, as an anti-bacterial or anti-fungal pharmaceutical composition, antibiotic, food preservative, cosmetic preservative, pharmaceutical preservative or feed additive preservative, and the like.
