本研究对1株传统中药杏香兔耳风来源真菌Penicillium sp. L02的次级代谢产物进行研究,从中分离得到1个新的andrastin型杂萜化合物atlantinone C（1）和4个类似物（2~5）。通过1D、2D核磁共振波谱、高分辨质谱和X-ray单晶衍射确定了新化合物1的平面结构和绝对构型。体外抗炎结果显示,化合物4和5对LPS诱导的RAW 264.细胞的NO释放具有显著的抑制活性,IC50值分别为29.09 ± 1.33 μM和26.71 ± 1.40 μM,强于阳性药吲哚美辛（36.69 ± 1.23 μM）。体外抗4种临床常见耐药菌活性测试表明,化合物1~5的最低抑菌浓度（MIC）均大于64.0 μg/mL。

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.
