Bistachybotrysins A–C (1–3), three phenylspirodrimane dimers representing an unusual [6,6,7,6]-tetracyclic skeleton with a central 2,10-dioxabicyclo[4.3.1]decan-7-ol core fused with two phenyl units, were isolated from a fungal strain, Stachybotrys chartarum CGMCC 3.5365. The structures of 1–3 were elucidated through extensive spectroscopic data analysis, including Mo₂(AcO)₄-induced and calculated electronic circular dichroism (ECD). 1 and 2 exhibited potent cytotoxicity against four human tumor cell lines with IC₅₀ values in the range of 2.8–7.5 μM. Furthermore, a possible biogenesis for 1–3 is proposed.

Bistachybotrysins A-C（1 - 3），表示与中央-2,10-二氧杂双环[4.3.1]癸-7-醇芯一个不寻常的[6,6,7,6] -tetracyclic骨架3个phenylspirodrimane二聚体融合有两个从真菌菌株Stachybotrys chartarum CGMCC 3.5365中分离出苯基单元。的结构1 - 3分别通过广泛的光谱数据分析阐明，含有Mo ₂（ACO）₄诱导的和计算的电子圆二色性（ECD）。1和2对具有IC _50的四种人类肿瘤细胞系表现出强力的细胞毒性值在2.8–7.5μM的范围内。此外，对于可能的生物合成1 - 3提出。
