A maleic anhydride derivative, botryoanhydride (1), and a chromone derivative, botryochromone (2), together with three known chromones, eugenitin (3), 6-hydroxymethyleugenin (4) and 6-methoxymethyleugenin (5), were isolated from cultures of the endophytic fungus BCC 54265 of the family Botryosphaeriaceae. The structures were elucidated on the basis of NMR, HRMS and CD data. Compound 2 showed weak cytotoxic activity to cancer cell-lines.
从葡萄座腔菌科内生真菌BCC 54265的培养物中分离出一种马来酸酐衍生物——葡萄孢酐(1)和一种色酮衍生物——葡萄孢色酮(2),以及三种已知色酮:丁香色原酮(3)、6-羟甲基丁香色原酮(4)和6-甲氧基甲基丁香色原酮(5)。通过核磁共振(NMR)、高分辨质谱(HRMS)和圆二色光谱(CD)数据对其结构进行了鉴定。化合物2对癌细胞系显示出微弱的细胞毒性活性。
