Article Description

Eight drimane sesquiterpenes (1-8), six isochromane derivatives (9-14), and three known compounds, daldinin B (15), 9α-hydroxy-6β-[(2E,4E,6E)- octa-2,4,6-trienoyloxy]-5α-drim-7-en-11,12-olide (16), and pergillin (17), were isolated from the EtOAc extract of the marine-derived fungus Aspergillus ustus 094102. The structures of the new compounds were elucidated on the basis of spectroscopic analysis. The cytotoxic effects on A549 and HL-60 cell lines were evaluated by SRB and MTT methods. Ustusorane E (13) showed significant cytotoxicity against HL-60 cells with an IC value of 0.13 μM. Ustusolates C (6) and E (8) exhibited moderate cytotoxicity against A549 and HL-60 cells with IC values of 10.5 and 9.0 μM, respectively, and ustusolate A (4) showed weak cytotoxicity against HL-60 and A549 cells with IC values of 20.6 and 30.0 μM, respectively. © 2009 American Chemical Society and American Society of Pharmacognosy.
