| Abstract: Objective To study the chemical composition and biological activity of secondary metabolites of Penicillium polonicum H92 from seawater sediments at the bottom of mangroves in Zhangjiang Estuary, Fujian. Methods Silica gel column chromatography, reversed-phase silica gel (ODS) column chromatography, gel (Sephadex LH-20) column chromatography, thin-layer chromatography, and semi-preparative high-performance liquid chromatography were used to analyze the organic solvent extraction of Penicillium polonicum H92, and the secondary metabolites were isolated and purified. Mass spectrometry (MS), nuclear magnetic resonance (NMR), ultraviolet spectroscopy (UV) and other modern spectroscopy techniques were used to identify the structure of the separated chemical constituents. Oseltamivir was used as a positive control drug to conduct neuraminidase (NA) activity test against influenza virus with the above compounds. Results Seven secondary metabolites were isolated from Penicillium polonicum H92, and four of which were identified as quinolinone compounds as Viridicatin (1), 3-O-Methylviridicatin (2), and Viridicatol (3), 3-Hydroxy-4-(3-methoxyphenyl)-2-quinolinone (4). Compound 5 and 6 were diketopiperazines as Cyclic (L-Phe-L-Trp) (5), and Fructigenine A (5). Compoundone 7 was elucidated as an alkaloid of Aurantiomide C. Conclusion The preliminary evaluation of biological activity showed that compounds 2 and 6 had different levels of inhibitory activity against influenza virus neuraminidase. |
