Purpose: 6-Shogaol is one of the spicy flavor ingredients of ginger and hydrolysis product of gingerols. The purpose of this study is to investigate the potential of 6-shogaol as a natural cosmetic raw material by examining cell protection and inflammation inhibitory activity in human dermal fibroblasts (HDFs).
Methods: To verify the cytoprotective effects of 6-shogaol, cell viability was measured by water-soluble tetrazolium salt (WST-1) assay. To verify the anti-inflammatory effects of 6-shogaol, we performed nuclear factor kappa-light-chain-enhancer of activated B cells (NFΚB) promoter luciferase assay to check the expression of NFΚB. Additionally, the expression of inflammation related gene such as cyclooxygenase 2 (COX2), receptor for advanced glycation end product (RAGE), tumor necrosis factor alpha (TNFΑ), interleukin 6 (IL6), and interleukin 8 (IL8) mRNA was measured by quantitative real-time polymerase chain reaction (qRT-PCR).
Results: 6-Shogaol showed no toxicity in HDFs at concentrations of 5, 10, 20, and 40 μM, respectively and the cell viability was increased in a dose dependent manner. qRT-PCR analysis showed 6-shogaol treatment downregulated the expression of NFΚB, COX2, RAGE, TNFΑ, IL6, and IL8 in a dose dependent manner, resulting that 6-shogaol leads to protective activities against inflammatory responses in HDFs.
Conclusion: As mentioned above, 6-shogaol restored cell viability and decreased the expression of inflammatory factors in a dose dependent manner. Consequently, these results suggest the possibility of 6-shogaol as cosmetic material preventing skin aging, through identified functions on cytoprotection and anti-inflammation.
