运用硅胶柱色谱、凝胶柱色谱和高效液相色谱等分离技术对一株海洋沉积物来源真菌Phellinus sp. HN-22大米发酵提取物的倍半萜类成分进行研究, 从中发现1个新的倍半萜类化合物(3S,6S,7S,10S)-tremulene-10,12-dihydroxy- 11-ylacetate (1)和7个已知的倍半萜类衍生物[6α-hydroxycinnamolide (2), 6β-hydroxycinnamolide (3), 3β-acetoxycinna- molide (4), Ceriponol D (5), 3β-hydroxycinnamolide (6), 2α,3β-dihydroxycinnamolide (7), 3β,6β-dihydroxycinnamolide (8)]. 新化合物1的结构通过高分辨电喷雾电离质谱(HR-ESI-MS)、核磁共振波谱法(NMR)和量子化学计算方法进行确定. 通过抑制炎症因子(NO)生成的活性测试显示, 化合物3能较好地抑制NO的生成, 其半抑制浓度(IC50)值为(27.78±0.04) μmol/L, 与阳性药物地塞米松(IC50值32.56±0.34 μmol/L)活性相当, 表现出较好的抗炎活性.

The study on sesquiterpenoids from a marine-derived fungus Phellinus sp. HN-22 led to the isolation and purifi- cation of a new sesquiterpene compound, (3S,6S,7S,10S)-tremulene-10,12-dihydroxy-11-ylacetate (1), and seven known sesquiterpenes derivatives, 6α-hydroxycinnamolide (2), 6β-hydroxycinnamolide (3), 3β-acetoxycinnamolide (4), Ceriponol D (5), 3β-hydroxycinnamolide (6), 2α,3β-dihydroxycinnamolide (7), and 3β,6β-dihydroxycinnamolide (8). The structure absolute configuration of the new compound was determined by high resolution electrospray ionization mass spectroscopy (HRESIMS), nuclear magnetic resonance (NMR) and electronic circular dichroism calculations (ECD) methods. Based on inhibiting effects of the production of inflammatory factor NO, compound 3 exhibited similar anti-inflammatory activity with a half maximal inhibitory concentration (IC50) value of (27.78±0.04) μmol/L as that of the positive control, dexamethasone (IC50=(32.56±0.34 μmol/L)).

Key words: marine-derived fungi, tremulane-type sesquiterpenes, drimane-type sesquiterpenes, separation and identification, anti-inflammatory activities
