摘要:

皮肤糖化反应是导致肤色暗黄、色斑、老化的一个重要因素,针对皮肤糖化问题,开发了一种生物活性多肽并进行护肤功效验证。AIMP1衍生肽(AdP)是由氨基酰tRNA合成酶相互作用多功能蛋白质1(AIMP1)衍生而来的寡肽,具有类AIMP1的多种生物活性。采用牛血清白蛋白(BSA)糖化和羰基化体系研究AdP的抗糖化效果,并对含AdP的样品进行了临床功效测试。结果表明:AdP可减缓BSA与葡萄糖的糖基化反应,减少蛋白质羰基的生成,具有浓度依赖性;皮肤角质层含水量显著提高27.32%,TEWL降低12.77%,R2值提高10.34%,ITA°值提高14.25%,皱纹面积减少12.14%,AdP可有效抑制蛋白糖化,具有提升屏障功能、祛黄提亮抗皱的功效。

Abstract:

Advanced glycation end-products (AGEs) are produced during protein glycation and associated with skin ageing. The AIMP1 derived peptide (AdP) which is derived from aminoacyl tRNA synthase interacting multifunctional protein 1 may be used as an inhibitor of glycation. This study evaluated the potential anti-glycation effect of AdP and its application in cosmetic. Thirty valid subjects were selected as the research subjects, and non-invasive instruments were used to detect and record the water content, TEWL, R2, ITA°, wrinkle area/AOI area in the test group and the control group at 0, 4 and 8 weeks using corresponding products. The results show that the glycosylation reaction between BSA and glucose is inhibited by AdP, and the formation of protein carbonyl is reduced in a concentration-dependent manner. The applications of AdP in cosmetic has significant effects on improving the stratum corneum water content, the R2 value, the ITA° value, and the reducing the TEWL value and wrinkles. These findings suggest that AdP may serve as an inhibitor of glycation and provide new insights into its application.

Key words: AIMP1 derived peptide, anti-glycosylation, efficacy study
