An unusual sesquiterpene glycoside trichoacorside A () and two novel sorbicillinoid glycosides sorbicillisides A () and B (), together with a known compound sorbicillin (), were isolated and identified from the culture extract of an endophytic fungus EN-586, obtained from the marine red alga . Trichoacorside A () is the first representative of a glucosamine-coupled acorane-type sesquiterpenoid. Their structures were elucidated based on detailed interpretation of NMR and mass spectroscopic data. The absolute configurations were determined by X-ray crystallographic analysis, chemical derivatization, and DP4+ probability analysis. The antimicrobial activities of compounds - against several human, aquatic, and plant pathogens were evaluated.
从海洋红藻中内生真菌 EN-586 的培养物提取物中分离并鉴定出一种不寻常的倍半萜糖苷曲考索苷 A()和两种新型的索比菌素糖苷索比利西林 A()和 B()，以及一种已知化合物索比菌素()。曲考索苷 A()是第一个氨基葡萄糖偶联阿科烷型倍半萜的代表。基于对 NMR 和质谱数据的详细解释，确定了它们的结构。通过 X 射线晶体学分析、化学衍生化和 DP4+概率分析确定了绝对构型。评估了化合物-对几种人类、水生和植物病原体的抗菌活性。
