| pentaketides relating to aspinonene and dihydroaspyrone from a marine-derived fungus, aspergillus ostianus. | three new pentaketides, aspinotriols a ( 1) and b ( 3) and aspinonediol ( 5), were isolated together with two known compounds, aspinonene ( 7) and dihydroaspyrone ( 9), from the marine fungus aspergillus ostianus strain 01f313, which was collected in pohnpei and cultured with bromine-modified artificial seawater. the structures of the new compounds were determined by spectroscopic analyses including 1d and 2d nmr. although 1 and 3 are diastereomers, they show nearly superimposable (1)h and (13)c ... | 2007 | 17994702 |
