摘要: 探讨分离、纯化和鉴定链霉菌BAF-0711发酵液中的抗肿瘤活性成分的方法。采用大孔吸附柱层析、硅胶柱层析等方法对该菌株的次级代谢产物进行分离纯化;根据理化性质和波谱学方法进行化学结构的鉴定;利用MTT法来检测化合物的抗肿瘤活性。从该菌株发酵液中分离到化合物BAF-0711-A。经波谱方法鉴定与文献中报道的bafilomycin A1同质。以拉帕替尼为对照,BAF-0711-A对乳腺癌细胞MB-45-3d有较强的增殖抑制活性,其IC50值为0.217 μmol/L。

Abstract: The purpose of the present study was to isolate,purify and identify components with antitumor activity produced by Streptomyces sp. BAF-0711.The secondary metabolite was isolated and purified by macroporous resin column chromatography,silica gel chromatography, etc.;the chemical structure was identified by physicochemical properties and spectroscopic methods;The antitumor activity was detected by MTT assay.As a result,compound BAF-0711-A was isolated from the fermentation broth of Streptomyces sp. BAF-0711 and was identified as bafilomycin A1 by spectroscopic methods.MTT assay showed that BAF0711-A had strong growth inhibitory activity compared with lapatinib on MDA-MB-453 cell,with IC50 value of 0.217 μmol/mL.

Key words: bafilomycin A1, macrolide antibiotic, isolation and purification, structural identification, antitumor activity
