Abstract:

Eight known alkaloids were isolated from jellyfish-derived fungus Aspergillus fumigatus SCSIO41214. These compounds were isolated by silica gel column chromatography, ostade-cylsilane (ODS), and high performance liquid chromatography (HPLC). The structure of 1 was identified by performing a comprehensive analysis of spectroscopic data and X-ray diffraction for the first time. The structures of 2 ~ 8 were elucidated by spectroscopic methods and by comparison with data from the literature. In bioassay, compound 4 showed weak inhibitory activity against lipopolysaccharide (LPS)-induced nitric oxide (NO) in RAW264.7 cells at the concentration of 10 μmol·L-1.

Key words: jellyfish, Aspergillus fumigatus SCSIO41214, alkaloid
