초음파 복합처리를 통한 참굴 펩타이드의 피부미백 및 피부면역 활성

초록

In this study, peptides were isolated from Crassostrea gigas using an ultrasonification process at 40˚C. The yield of the peptides was greater than 34%, and their cytotoxicity was found to be less than 22.8% against several cell lines that were treated with the extracts at a dose of 1.0 mg/mL. In addition, the tyrosinase inhibitory and melanin synthesis of the peptides isolated from Crassostrea gigas were also evaluated to determine if they could be used as a potential cosmetic agent. The peptides were found to significantly inhibit the melanin synthesis of the clone M-3 cell line by up to 62.7%. The inhibitory activities of the tyrosinase were observed 34.51% in ascorbic acid, 42.49% in extract with the ultrasonification at 40˚C and 35.37% in 40˚C extract at 1.0 mg/mL concentration, respectively. Finally, when samples were treated with the peptide extracts at a concentration of 0.6 mg/mL, PGE2 expression was significantly decreased. Taken together, these results indicate that Crassostrea gigas may be a source of cosmetic agents capable of improving physiological hyperpigmenting and immunomodulating skin disorders.
