Abstract: The present invention relates to a peptide with amidated carboxy terminus having melanogenesis inhibitory activity and a composition comprising same, and more specifically, to a peptide with amidated (—NH2) carboxy terminus, composed of one amino acid sequence selected from the group consisting of SEQ ID NO: 3, SEQ ID NO: 5, SEQ ID NO: 9 to 18, and a pharmaceutical composition, cosmetic composition, and food composition for the treatment of pigmentation diseases comprising same as an active ingredient.

Abstract: The present invention relates to a peptide having inhibitory activity against melanogenesis and a composition comprising the same and, more particularly, to a peptide having melanogenesis-inhibiting activity and a pharmaceutical, a cosmetic, and a food composition comprising the same as an effective ingredient for whitening the skin, the peptide comprising an amino acid sequence represented by General Formula (I) amino terminus-X1-X2-X3-Leu-X4-carboxy terminus, wherein X1 is Asn or Ser; X2 is an amino acid selected from the group consisting of Asn, His, and Asp; X3 is His or Asn; and X4 is Gly or Phe. Exhibiting the effect of very effectively inhibiting the activity of enzymes and proteins which are associated with melanin biosynthesis, without decreasing cell viability, the peptide according to the present invention can be usefully utilized in developing skin-whitening medications, cosmetics, and functional foods.
