摘要: 本文通过硅胶柱层析和半制备HPLC对放线菌HCCB11431的代谢产物进行了分离纯化,得到了2个新化合物和4个已知的化合物,经IR、MS和NMR等波谱数据鉴定出结构,分别为:3-(3-acetoxy-4-methoxy-5-methylphenyl)-2-aminopropanoic acid (1)、3-(3-acetoxy-4-hydroxyl-5-methyphenyl)-2-aminopropanoic acid (2)、2′-dexoyadenosine (3)、Cytidine (4)、Uridine (5)、2′-deoxycytidine (6),其中化合物1和2为新化合物。细胞毒活性表明,化合物1~6对不同的肿瘤细胞都有一定的抑制作用,其中化合物2~4对三种肿瘤细胞均有较高的抑制作用,对MCF-7的抑制作用较明显,IC50分别为7.9、10.1、9.5 μg/mL。

Abstract: Two new compounds 1-2 and four known compounds 3-6 were isolated from the fermentation broth of Streptomyces sp.HCCB11431 by using silica gel column chromatography and semi-preparative HPLC chromatography.They were identified as 3-(3-acetoxy-4-methoxy-5-methylphenyl)-2-aminopropanoic acid (1), 3-(3-acetoxy-4-hydroxyl-5-methyphenyl)-2-aminopropanoic acid (2), 2′-dexoyadenosine (3), Cytidine (4), Uridine (5), 2′-deoxycytidine (6) based on the date of IR,MS and NMR.All compounds exhibited cytotoxicity against breast cancer cell line MCF-7,pancreatic cancer cell line PANC-1 and prostatic cancer cell line Du145. Compounds 2-4 showedstrong inhibitory against MCF-7 with IC50 values of 7.9,10.1 and 9.5 μg/mL,respectively.
