3-6, together with the known secalonic acid D (7), were isolated from a fermentation culture of the fungus Aspergillus aculeatus. Their structures and absolute configurations were established by analyses of their spectroscopic data, including 1D and 2D-NMR spectra, HR-ESIMS, electronic circular dichroism (ECD) data, and quantum chemical calculations. These metabolites were evaluated for in vitro cytotoxic
六个倍半萜类化合物1-6,包括两个新的,一种ent-daucane型倍半萜类化合物,曲霉A(1)和一个正癸烷一个,asperaculane B(2),以及四个已知的降丁烷衍生物,aculenes AD 3-6,以及从真菌曲霉曲霉的发酵培养物中分离出已知的乙二醛酸D(7)。通过分析其光谱数据,包括1D和2D-NMR光谱,HR-ESIMS,电子圆二色性(ECD)数据以及量子化学计算,可以确定它们的结构和绝对构型。评估了这些代谢物对两种细胞系,人癌细胞系(HeLa)和一种正常仓鼠细胞系(CHO)的体外细胞毒活性。
