| 摘 要： | 研究海绵来源真菌Aspergillus repens发酵产物中的活性代谢产物.分离培养微生物进行活性筛选,采用活性追踪的方法、利用色谱手段分离获得单体化合物,根据波谱分析及其理化性质确定其结构,利用SRB评价单体化合物的抗肿瘤活性,利用纸片法测定单体化合物的抗植物病菌活性.获得1个萘并吡喃酮化合物,其结构鉴定为3,4-二氢-9,10-二羟基-7-甲氧基-3-甲基-1H-萘并2,3c]吡喃-1-酮 (Semivioxanthin).该化合物对肿瘤细胞A-549、HL-60和BEL-7402有一定抑制作用,对植物致病菌作用较强.海绵微生物代谢产物是发现活性物质重要资源,值得深入研究.

| Abstract: | To investigate the bioactive metabolites of sponge-derived fungus Aspergillus repens.Sponge-derived fungi were isolated and cultivated.The bioactive compounds were isolated by bioassayguided separation procedure and their structures were identified by means of spectral analysis and physicochemical properties.Their bioactivities were preliminarily evaluated in vitro by the SRB and paper method.An anthraquinone was isolated and its structure was identified as 3,4-Dihydro-9,10-dihydroxy-7-methoxy-3-methyl-1H-n... |
