Two aromatic butenolides, aspernolides A and B along with the known metabolites, butyrolactone I, terrein and physcion were isolated from the fermentation broth of a soft coral derived fungus Aspergillus terreus. The structures of these metabolites were assigned on the basis of detailed spectroscopic analysis. The absolute stereochemistry of aspernolides A (1) and B (2) was established by their preparation
两种芳香丁烯内酯、aspernolides A 和 B 以及已知的代谢物、丁内酯 I、terrein 和 physcion 从软珊瑚衍生的真菌 Aspergillus terreus 的发酵液中分离出来。这些代谢物的结构是根据详细的光谱分析确定的。Aspernolides A (1) 和 B (2) 的绝对立体化学是通过它们从已知的丁内酯 I 中制备的。生物遗传学 aspernolides A 和 B 必须来源于丁内酯 I,一种众所周知的细胞周期蛋白依赖性激酶 (cdk) 的特异性抑制剂来自A. 土星。测试时,aspernolide A 对癌细胞系表现出轻微的细胞毒性。
