Three new meroterpenoids, named austalides S-U (1-3), were isolated from the culture of a sponge-derived fungus Aspergillus aureolatus HDN14-107, together with eleven known austalides derivates (4-14). Their structures, including absolute configurations, were assigned on the basis of NMR, MS data, and TDDFT ECD calculations. Compound 1 is the first case of austalides with the terpene ring fused to the chroman ring in trans configuration. Compounds 3 and 5 exhibited activities against influenza virus A (H1N1), with IC50 values of 90 and 99 μM, respectively.
从海绵来源的真菌 Aureolatus HDN14 - 107 的培养物中分离出三种新的半萜类化合物，命名为澳洲内酯 S - U（1 - 3），同时还分离出了十一种已知的澳洲内酯衍生物（4 - 14）。它们的结构，包括绝对构型，是根据核磁共振（NMR）、质谱（MS）数据以及含时密度泛函理论（TDDFT）电子圆二色光谱（ECD）计算确定的。化合物 1 是首例萜烯环与色满环以反式构型稠合的澳洲内酯。化合物 3 和 5 对甲型流感病毒（H1N1）表现出活性，其半数抑制浓度（IC50）值分别为 90 和 99 μM。
