通过人工发酵培养,利用层析技术,从南海红树林内源真菌#2240的培养液中分离得到3个蒽醌类次级代谢产物,它们分别是:(+)-3,3',7,7',8,8'-六羟基-5,5'-二甲基连二蒽醌(化合物1),1,4,5-三羟基-7-甲基蒽醌(化合物2)和1,6,8-三羟基-3-甲基蒽醌(化合物3),其中化合物1为新化合物. 它们的结构通过谱图分析(包括1H、13C NMR、DEPT、HMQC、HMBC、HREIMS、UV-Vis及IR等)和相关文献得以确定. 初步药理实验表明,化合物1对DNA拓扑异构酶(hTopo I)具有强抑制活性,最低抑制浓度2.35×10-4 mol/L,结果远低于阳性对照物喜树碱之值1.00×10-3 mol/L.
