undescribed bisabolane derivatives, trichaspin, trichaspsides A and B, three undescribed cyclonerane sesquiterpenes, 9-cycloneren-3,7,11-triol, 11-cycloneren-3,7,10-triol, and 7,10-epoxycycloneran-3,11,12-triol, and one undescribed harziane diterpene, 11-hydroxy-9-harzien-3-one, were obtained from the culture of Trichoderma asperellum cf44-2, an endophyte of the marine brown alga Sargassum sp. Their structures
三种未描述的红没药烷衍生物,trichaspin,trichaspsides A 和 B,三种未描述的 cyclonerane 倍半萜,9-cycloneren-3,7,11-triol,11-cycloneren-3,7,10-triol,和 7,10-epoxycycloneran-3 11,12-三醇和一种未描述的 harziane 二萜 11-hydroxy-9-harzien-3-one 是从 Trichoderma asperellum cf44-2(一种海藻马尾藻属的内生菌)的培养物中获得的。它们的结构和相对构型是通过 1D/2D NMR 和 MS 数据分析确定的,它们的绝对构型是通过 ECD 或特定旋光度数据确定的。Trichaspin 具有前所未有的乙基化红没药烷骨架,而 trichaspsides A 和 B 分别代表红没药烷和降红没药烷倍半萜的第一个氨基糖苷。
