对深海来源真菌Talaromyces indigoticus FS688进行化学成分研究, 从中发现了3个新的聚酮类化合物以及5个已知化合物, 其化学结构是通过综合的波谱分析得以确定, 同时其绝对构型是通过理论电子圆二色谱(ECD)计算确定. 其中, 5-甲基六氢呋喃[2,3-b]呋喃-2-基-乙烷-1-醇(2)对所测试的4株人体肿瘤细胞株(SF-268, MCF-7, HepG-2和A549)表现出显著的细胞毒活性, IC50介于0.18~0.53 µmol/L之间.

The chemical investigation of the deep-sea-derived fungus Talaromyces indigoticus FS688 led to the isolation of three new polyketides together with five known compounds. Their structures were determined by comprehensive spectroscopic analysis and the absolute configurations were evaluated by theoretical electrostatic circular chroism (ECD) calculations. Among them, 5-methylhexahydrofuro[2,3-b]furan-2-yl-ethan-1-ol (2) exhibited significant cytotoxicity against the four tested human tumor cell lines (SF-268, MCF-7, HepG-2 and A549) with the IC50 values in the range of 0.18~0.53 µmol/L.

Key words: Talaromyces, deep-sea-derived fungus, polyketide, spectroscopic analysis, cytotoxicity
