Sesquiterpenes From Oplopanax elatus Stems and Their Anti-Photoaging Effects by Down-Regulating Matrix Metalloproteinase-1 Expression via Anti-Inflammation. Front Chem 2021; 9:766041. [PMID: 34805098 PMCID: PMC8600134 DOI: 10.3389/fchem.2021.766041] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 10/11/2021] [Indexed: 11/23/2022] Open
Abstract
In the process of continuing to investigate ultraviolet b (UVB) irradiation protective constituents from Oplopanax elatus stems, nine new sesquiterpenes, named as eurylosesquiterpenosides A–D (1–4), eurylosesquiterpenols E–I (5–9), and ten known ones (10–19) were gained. Their structures were established by analysis of their NMR spectroscopic data, and electronic circular dichroism calculations were applied to define their absolute configurations. In addition, UVB induced HaCaT cells were used to study their anti-photoaging activities and mechanism. The results consolidated that compounds 7, 11, and 14 could improve the survival rate of HaCaT cells in concentration dependent manner at 10, 25, and 50 μM. Furthermore, western blot assay suggested that all of them could inhibit the expression of matrix metalloproteinase-1 (MMP-1), and increase the level of type I collagen markedly. Compounds 11 and 14 could reduce the phosphorylation of extracellular signal-regulated kinase and p38, respectively. Besides, compounds 7, 11, and 14 could significantly down-regulate the expression of inflammation related protein, such as tumor necrosis factor-α and cyclooxygenase-2, which indicated that they played anti-photoaging activities by reducing MMP-1 expression via down-regulating the production of inflammatory mediators and cytokines in UVB-induced HaCaT cells.

Abstract
The chemical compositions of the water-distilled essential oil of Stachys cretica ssp. lesbiaca Rech. fil. and S. cretica ssp. trapezuntica Rech. fil. were determined by GC and GC–MS. Altogether 63 compounds were identified. The sesquiterpene hydrocarbon, germacrene D (20.3% and 12.9% respectively) was the main component identified in both oils. Furthermore, ethanol, light petroleum, dichloromethane, ethyl acetate and n-butanol extracts prepared from the aerial parts of the plants were tested for their antimicrobial activities against six bacterial strains and the yeast Candida albicans. The extracts exhibited no antibacterial activity, but the light petroleum and n-butanolic fractions showed low antifungal activities. Crude ethanolic extracts of the two subspecies were tested for their ability to inhibit the growth of HL-60 and Ishikawa human tumor cell lines. The IC50 values were 100 μg/mL for the HL-60 cell line and 200 μg/mL for the Ishikawa cell line.
