A new andrastin-type meroterpenoids derivative, atlantinone C (1) and four known analogues, including bialorastin C (2),peniciterpenolide A (3),peniandrastin G (4),10-formyl andrastone A (5) were isolated from an endophytic fungus Penicillium sp. L02 in this study. Their structures were elucidated by detailed analysis of comprehensive spectroscopic data, and the structure of 1 was further determined by X-ray diffraction analysis. In vitro anti-inflammatory assays revealed that compounds 4 and 5 exhibited significant inhibitory activities against NO production in LPS-induced RAW 264.7 cells, with IC50 values of 29.09 ± 1.33 μM and 26.71 ± 1.40 μM, respectively, which were more potent than the positive control indomethacin (36.69 ± 1.23 μM). In vitro antibacterial evaluation against four common clinical drug-resistant bacteria indicated that the MIC of compounds (1-5) were greater than 64.0 μg/mL, showing no clinically significant antibacterial activity.

Key words: Ainsliaea fragrans Champ., Penicillium sp. L02, endophytic fungus, secondary metabolites, structural identification, anti-inflammatory activity, antibacterial activity
