Abstract Nine new C-9 polyketides, named aspiketolactonol (1), aspilactonols A-F (2-7), aspyronol (9) and epiaspinonediol (11), were isolated together with five known polyketides, (S)-2-(2'-hydroxyethyl)-4-methyl-gamma-butyrolactone (8), dihydroaspyrone (10), aspinotriol A (12), aspinotriol B (13) and chaetoquadrin F (14), from the secondary metabolites of an Aspergillus sp. 16-02-1 that was isolated from a deep-sea sediment sample. Structures of the new compounds, including their absolute configurations, were determined by spectroscopic methods, especially the 2D NMR, circular dichroism (CD), Mo-2-induced CD and Mosher's H-1 NMR analyses. Compound 8 was isolated from natural sources for the first time, and the possible biosynthetic pathways for 1-14 were also proposed and discussed. Compounds 1-14 inhibited human cancer cell lines, K562, HL-60, HeLa and BGC-823, to varying extents.
