Two new oxidized sterols 1 and 2 were obtained from the active fraction of a mangrove fungus Aspergillus awamori isolated from the soils around the mangrove plant Acrostichum speciosum. Their structures were elucidated using spectroscopic methods as 22E-7α-methoxy-5α,6α-epoxyergosta-8(14),22-dien-3β-ol (1) and 22E-3β-hydroxy-5α,6α,8α,14α-diepoxyergosta-22-en-7-one (2). The NMR data and complete assignments for both DMSO-d6 and CDCl3 were given. Their cytotoxic activity against A549 cell line was evaluated. Furthermore, the detailed conformation analysis for ring B (cyclohexene oxide system) of sterol 1 was given on the basis of NOEs. The endo-boat conformation was considered as the preferred conformation for ring B rather than half-chair conformation. Copyright © 2009 John Wiley & Sons, Ltd. |
