marine zooplankton, Artemia salina. Myrochromanosides A and B exhibited obvious inhibitory against three tested microalgae with IC50 values in the range of 9.2–108.9 μM. 8α-Hydroxyroridin H, roridin A and verrucarin A exhibited significant inhibition against P. donghaiense with IC50 values of 6.1, 5.8, and 6.0 μM and toxicity against brine shrimp larvae with LC50 values of 1.4, 2.8, and 0.26 μM, respectively
从贝类衍生真菌Albifimbria verrucaria CD1的培养物中分离出八种 myrochromanol 类似物,包括 C-2 处的三对差向异构体和 myrochromanol 支架和两个带有糖部分连接在 C-4 的 myrochromanol 实例,以及十二种单端孢霉烯衍生物-4。其中,8个化合物命名为2- epi -myrochromanol、ent -myrochromanol B、4- epi -myrochromanol B、2- epi - myrochromanol A、myrochromanosides A和B、6',7'- erythro- (2'E ,4 ′ Z )-trichoverrol B, 3 R ,8 S-dihyroxyroridin H 是以前未描述的真菌代谢物。它们的平面结构和相对构型通过 1D 和 2D NMR 以及 HR-MS 数据分析确定,它们的绝对构型使用改进的
