Sporulosol (1), a new ketal, together with four known compounds, has been isolated from the liquid fermentation cultures of a wetland-soil-derived fungus, Paraconiothyrium sporulosum. Its structure was elucidated primarily by NMR experiments, and was further confirmed by X-ray crystallography. Sporulosol was obtained as a racemic mixture and the resolved two enantiomers racemized immediately after
从湿地土壤衍生真菌孢子霉菌的液体发酵培养物中分离出一种新的缩酮Sporulosol(1)和四种已知化合物。主要通过NMR实验阐明其结构,并通过X射线晶体学进一步证实。以外消旋混合物的形式得到孢子醇,手性分离后立即将拆分的两个对映异构体消旋。孢粉醇似乎是第一个衍生自6H-苯并[c] chromen-6-和苯并呋喃酮单元的缩酮。该化合物对人肿瘤细胞系T24表现出适度的细胞毒性,IC50值为18.2 µM。
