摘要: 本论文对中国南海来源真菌Penicillium sp. SCSIO 40438的次级代谢产物进行研究。通过硅胶柱色谱、Sephadex LH-20凝胶柱色谱以及高效液相色谱等多种分离方法对该菌株的发酵产物进行分离纯化,利用核磁共振和高分辨质谱等波谱学方法对分离得到的化合物进行结构鉴定。从中共分离鉴定到9个化合物:1-(2-Methylbut-3-en-2-yl)-1H-indole-3-carbaldehyde (1)、1-methyl-2(1H)-quinazolinone (2)、fructigenine A (3)、fructigenine B (4)、2-[(s)-hydroxy(phenyl)methyl]-3-methylquinazolin-4(3H)-one (5)、3-methylviridicatin (6)、3-O-methylviridicatol (7)、viridicatol (8)和(+)-cyclopenol (9),其中化合物1和2为新天然产物。抑菌活性实验表明,化合物8具有中等强度的抑制金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌活性,最低抑菌浓度为8.0 μg mL-1。

Abstract: This experiment aims to study the secondary metabolites from the South China Sea derived fungus Penicillium sp. SCSIO 40438. The solid fermentation products of the strain were isolated and purified by a variety of separation methods, including silica gel column, Sephadex LH-20 gel column, and preparative high performance liquid chromatography. The structures of the isolated compounds were identified by nuclear magnetic resonance, high resolution electrospray ionization mass spectroscopy and comparison with the reported data. Nine compounds were obtained and identified as 1-(2-Methylbut-3-en-2-yl)-1H-indole-3-carbaldehyde (1)、1-methyl-2(1H)-quinazolinone (2), fructigenine A (3), fructigenine B (4), 2-[(s)-hydroxy(phenyl)methyl]-3-methylquinazolin-4(3H)-one (5), 3-Methylviridicatin (6), 3-O-methylviridicatol (7), viridicatol (8), (+)-cyclopenol (9), and compounds 1 and 2 are two new natural products. Compound 8 showed moderate antibacterial activities against Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus with minimal inhibition concentration (MIC) values of 8.0 μg mL-1.
