摘要
从海洋真菌根霉2-PDA-61中共发现6个已知化合物,其中包括2个细胞毒活性的环五肽(1和2)和4个苯的衍生物(3~6)。通过波谱学数据分析和与已知化合物数据比较,这些化合物分别被鉴定为malformin C(1)、malformin A1(2)、2,5-二羟基苯乙酸甲酯(3)、对羟基苯乙醇(4)、对甲基苯乙醇(5)和对苯二甲醚(6)。化合物1和2对P388细胞系表现出中等强度的细胞毒活性,IC50值分别为1.8μM和4.2μM。
Two cytotoxic cyclicpentapeptides(1 and 2) and four benzene derivatives(3-6) have been isolated from the marine-derived fungus Rhizopus sp.2-PDA-61.By spectral analysis and comparison the data with those of known compounds,they were identified as malformin C(1),malformin A1(2),2,5-dihydroxyphenylacetic acid methyl ester(3),p-hydroxy phenylethanol(4),p-methyl phenylethanol(5),and p-dimethoxybenzene(6),respectively.Moreover,compounds 1 and 2 displayed moderate cytotoxicities to P388 cell lines,and the IC50 values of them were 1.8 μM and 4.2 μM.
