HPLC/microtiter-plate-based generation of activity profiles the extract of a marine alga-derived fungus, identified as Gliocladium sp., was shown to contain the known strongly cytotoxic metabolite 4-keto-clonostachydiol (1) and also clonostachydiol (2) as well as gliotide (3), a new cyclodepsipeptide containing several D-amino acids. The absolute configuration of 1 was elucidated by reduction to 2,
使用基于HPLC /微量滴定板的活性谱图生成方法,鉴定为Gliocladium sp。的海藻衍生真菌提取物含有已知的强细胞毒性代谢物4-酮-clonostachydiol(1)以及clonostachydiol(2) )和格列肽(3),这是一种新的含有两个D-氨基酸的环二肽。通过还原为2来阐明1的绝对构型,并制备了氯氧水苏糖醇的另外两种氧化衍生物(5、6),并对其生物学活性进行了评估。
