内生真菌Penicillium spinulosum次级代谢产物及其促血管生成、抗微生物活性研究

Proangiogenic and antimicrobial activities of secondary metabolites from the endophytic fungus Penicillium spinulosum

  • 摘要: 本研究采用多种色谱技术从一株香果树内生真菌Penicillium spinulosum大米发酵产物中获得7个次级代谢产物, 经核磁、质谱等波谱学方法结合文献数据对这些化合物进行了结构鉴定, 分别为spinulacid (1), ascomindone A (2), ascomindone C (3), monomethylsulochrin (4), barceloneic acid A (5), flufuran (6) 和5-hydroxymethyl-furaldehyde (7), 其中化合物1为新苯甲酸类衍生物。药理活性评价显示, 化合物1256在20和40 μmol·L-1浓度下对转基因斑马鱼具有显著的促血管生成活性(动物实验获得山东省科学院生物研究所实验动物福利伦理委员会批准, 批准号为SWS20240611); 化合物14对禾谷镰刀菌表现出中等或强的抗真菌活性, 其最小抑菌浓度(MIC) 分别为12.5和6.25 μg·mL-1; 此外, 化合物4对金黄色葡萄球菌和欧文杆菌也显示出明显的抗菌活性, 其MIC值分别为6.25和12.5 μg·mL-1

     

    Abstract: A new benzoic acid derivative, spinulacid (1), together with six known compounds ascomindone A (2), ascomindone C (3), monomethylsulochrin (4), barceloneic acid A (5), flufuran (6), and 5-hydroxymethyl-furaldehyde (7) were obtained from the rice fermentation extract of an endophytic fungus Penicillium spinulosum isolated from Emmenopterys henryi Oliv. by various chromatographic techniques. Their structures were elucidated by the analysis of NMR data, MS and comparison with literature. The biological activity results showed that compounds 1, 2, 5, and 6 exhibited significant proangiogenic activity in transgenic zebrafish at concentrations of 20 and 40 μmol·L-1 (the animal experiment was approved by the Animal Ethical and Welfare Committee of Biology Institute, Shandong Academy of Science, the approval number is SWS20240611). Compounds 1 and 4 displayed moderate or strong antifungal activity against phytopathogen Fusarium graminearum with minimum inhibitory concentration (MIC) values of 12.5, and 6.25 μg·mL-1, respectively. Besides, compound 4 was also found to show obvious antibacterial activity against Staphylococcus aureus and Erwinia carotovora with MIC values of 6.25 and 12.5 μg·mL-1, respectively.
