Two new compounds, (7 2 5)-3,5,7-trimethyl-2,5-octadienedioic-8-methyl ester () and neovasipyridone G (), together with a new natural product compound (725)-3,5,7-trimethyl-2,5-octadienedioic acid (), and six known compounds () were isolated from sp. SYPF7381. Their structures were elucidated on the basis of extensive spectroscopic analysis, and the absolute configurations of compounds and were determined by optical rotation. The absolute configuration of compound was determined by means of electronic circular dichroism (ECD) calculation. In addition, the anti-inflammatory activities of all compounds were assayed in RAW 264.7 cells by assessing LPS-induced NO production. Furthermore, the structure-antiinflammation activity relationships for these isolated compounds were summarized based on the experimental as well as the docking results.
