    摘要:

    【背景】海洋来源真菌次级代谢产物由于具有化学结构新颖和生物活性多样的特点,是药物发现新的源泉之一。【目的】研究Parengyodontium album SCSIO 40430次级代谢产物及其抑菌活性。【方法】利用常压柱色谱、半制备HPLC等色谱学方法对P. album SCSIO 40430发酵液粗提物进行分离纯化;通过HR-ESI-MS、1H、13C NMR等光谱学方法,并结合文献数据,确定其产生的化合物结构;对分离得到的化合物进行抑菌活性测试。【结果】分离到3个苯并二氢吡喃酮类化合物,结构确定为deoxyphomalone (1)、2-ethyl-3,5-dihydroxy-11- methylchroman-9-one (2)、2-ethyl-3-hydroxy-5-methoxy-11-methylchroman-9-one (3)。【结论】获得3个苯并二氢吡喃酮类化合物;活性测定结果显示化合物2对耐甲氧西林金黄色葡萄球菌(MRSA ATCC 43300)、苏云金芽孢杆菌(B. thuringiensis SCSIO BT01)有较好的生长抑制活性(MIC 16 μg/mL)。

    Abstract:

    [Background] Marine-derived fungi are prolific resources of natural products due to their diversity and ability to produce novel bioactive compounds. [Objective] To obtain the bioactive secondary metabolites from the fungus Parengyodontium album SCSIO 40430, which isolated from a Montipora foliosa sample from the South China Sea, and to evaluate for their antibacterial activity. [Methods] The compounds were isolated and purified by silica gel column, Sephadex LH-20 column and semi-prepartive HPLC chromatography. Their structures were identified by HR-ESI-MS, 1H, 13C NMR, and comparison with the data of literatures. [Results] Three compounds were isolated from the butanone extract and structurely identified as deoxyphomalone (1), 2-ethyl-3,5-dihydroxy-11-methylchroman- 9-one (2) and 2-ethyl-3-hydroxy-5-methoxy-11-methylchroman-9-one (3). [Conclusion] Three chromanone compounds were aquired, and compounds 2 displayed antibacterial activities of Methicillin-resistant Stphylococcus and Bacillus thuringiensis SCSIO BT01 (MIC 16 μg/mL).
