海洋来源真菌Penicillium citrinum中的一个新半缩醛类化合物 (英文)

A novel hemiacetal from the marine-derived fungus Penicillium citrinum

  • 摘要:

    利用硅胶、Sephadex LH-20及半制备HPLC等柱色谱方法从一株海洋来源真菌Penicillium citrinum中分离得到了一个结构新颖的半缩醛类化合物 (1)。通过高分辨电喷雾质谱、一维以及二维核磁等方法确定了它的平面和立体结构, 同时, 从核磁谱图中发现了化合物1在溶剂中是以互变异构体的形式存在的。在对人白血病细胞HL-60人肺癌细胞A-549、人宫颈癌细胞HeLa以及人白血病细胞K5624种细胞株的抗肿瘤活性筛选中, 发现化合物1对人白血病细胞HL-60显示弱的抑制活性, IC50值为77.4 μmol·L−1

     

    Abstract:

    A novel hemiacetal, citrinacetal (1) was isolated from a marine-derived fungus Penicillium citrinum by column chromatography on silica gel, Sephadex LH-20 and semi-preparative HPLC.  Its structure and stereochemistry was established on the basis of HR-ESI-MS, 1D and 2D NMR spectroscopic methods.  The NMR spectrum showed this compound exists in solution as a mixture of two stereoisomers.  The cytotoxic effect of compound 1 was evaluated in A-549, HL-60, HeLa, and K562 cancer cell lines.  However, compound 1 only displayed weak cytotoxic activity on HL-60 cell, with IC50 value 77.4 μmol·L−1.
