A new hybrid polyketide, cladodionen (1), together with a new abscisic acid analogue, cladosacid (2), were isolated from the marine-derived fungus, Cladosporium sp. OUCMDZ-1635. Their structures, including the absolute configurations, were fully elucidated on the basis of spectroscopic analysis, ECD spectra, quantum chemical calculations, and chemical methods. Cladodionen (1) showed cytotoxic activities against MCF-7, HeLa, HCT-116, and HL-60 human cancer cell lines with IC50 values of 18.7, 19.1, 17.9, and 9.1 µM.
从海洋真菌 Cladosporium sp. OUCMDZ-1635 中分离出了一种新的杂交多酮--cladodionen(1)和一种新的脱落酸类似物--cladosacid(2)。根据光谱分析、ECD 光谱、量子化学计算和化学方法,完全阐明了它们的结构,包括绝对构型。Cladodionen (1) 对 MCF-7、HeLa、HCT-116 和 HL-60 人类癌细胞株具有细胞毒性活性,IC50 值分别为 18.7、19.1、17.9 和 9.1 µM。
