Structure-activity relationship of anti-inflammatory meroterpenoids isolated from Dictyopteris polypodioides in RAW264 cells.
In this study, we explored anti-inflammatory compounds from the brown alga Dictyopteris polypodioides and isolated 7 meroterpenoids. Their anti-inflammatory activities were evaluated using the lipopolysaccharide-stimulated mouse macrophage cell line, RAW264. Yahazunol (1) exhibited similar nitric oxide (NO) production inhibitory activity as zonarol (2), which has previously been shown to be an anti-inflammatory compound. Yahazunol (1), zonarol (2), and isozonarol (3) inhibited not only NO production but also inducible nitric oxide synthase, interleukin-6, and C-C motif chemokine ligand 2 mRNA expression in RAW264 cells. The structure-activity relationships of the 11 compounds, including their synthetic analogs, revealed the significance of the hydroquinone moiety in the anti-inflammatory activity of these sesquiterpenoids in RAW264 cells. Diacetylated zonarol (9) exhibited an activity comparable to that of zonarol as a result of intracellular deacetylation. These results provide new insights into the anti-inflammatory activity of hydroquinone-containing natural products.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
