摘要: 采用MTT法检测细胞存活率,利用α-促黑素(α-MSH)诱导的B16小鼠黑色素瘤细胞模型和UVB照射诱导豚鼠皮肤色素沉着模型对棕榈酰三肽-5的美白功效进行评价。研究了其对细胞内酪氨酸酶活性、小眼畸形相关转录因子(MITF)和酪氨酸酶mRNA水平的影响。结果表明,棕榈酰三肽-5能够显著降低上清及细胞内的黑色素水平且无细胞毒性。进一步研究发现,棕榈酰三肽-5通过抑制酪氨酸酶活性,下调MITF和酪氨酸酶的mRNA水平,从而抑制黑色素的生成。在动物模型中,棕榈酰三肽-5能够显著降低UVB照射诱导的豚鼠皮肤色素沉着和黑色素分布区域灰度值(P<0.05)。

Abstract: To evaluate skin whitening efficacy and mechanism of palmitoyl tripeptide-5,the cell viability was detected by MTT method,B16 guinea pig melanoma cell models treated by α-melanocyte stimulating hormone (α-MSH) and hyperpigment of UVB-stimulated dorsal skin of guinea pigs were measured.Activity of tyrosinase,the mRNA expression of MITF and tyrosinase were investigated.Results show that palmitoyl tripeptide-5 exert a skin whitening efficacy by inhibiting melanin production via downregulation of MITF and tyrosinase expression,inhibiting activity of tyrosinase in melanocytes.Colorimetric analysis shows that the palmitoyl tripeptide-5 significantly inhibit the pigmentation and reduce the gray value in UVB-irradiated guinea pig dorsal skin area (P<0.05).

Key words: whitening, palmitoyl tripeptide-5, UVB, B16 cell, guinea pig
