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.
