Seven new phenolic bisabolane sesquiterpenoids (1–7), along with 10 biogenetically related analogues (8–17), were obtained from the deep-sea-derived fungus Aspergillus versicolor YPH93. The structures were elucidated based on extensive analyses of the spectroscopic data. Compounds 1–3 are the first examples of phenolic bisabolanes that contain two hydroxy groups attached to the pyran ring. The structures
从深海真菌Aspergillus versicolor YPH93 中获得了 7 种新的酚类红没药烷倍半萜类化合物 ( 1 – 7 ) 以及 10 种生物遗传学相关的类似物 ( 8 – 17 )。基于对光谱数据的广泛分析,阐明了这些结构。化合物1 – 3是含有两个连接到吡喃环的羟基的酚类红没药烷的第一个例子。对 sydowic 酸衍生物 ( 1 – 6和8 – 10 ) 的结构进行了仔细研究,导致对六种已知类似物的结构进行了修改,包括对 sydowic 酸 ( 10 ) 绝对构型的修改。评估所有代谢物对铁死亡的影响。化合物7对erastin/RSL3诱导的铁死亡有抑制作用,EC 50值范围为2至4μM,而对TNFα诱导的坏死性凋亡或H 2 O 2诱导的细胞坏死没有影响。
