中文摘要:
      目的对1株西沙群岛永兴岛海域来源短指软珊瑚sinularia sp.共附生真菌Penicillium sclerotiorum中的azaphilones类化合物及其生物活性进行研究。方法利用硅胶柱层析、薄层色谱、Sephadex LH-20凝胶柱层析、MPLC、HPLC等分离手段对菌株发酵提取物进行分离和纯化;运用NMR、MS等现代波谱学方法,并结合相关文献数据比对,鉴定化合物的结构;通过细胞毒活性模型评价化合物抗肿瘤活性。结果从真菌Penicillium sclerotiorum的代谢产物中获得了9个azaphilones类合物,分别(+)-Sclerotiorin(1), Isochromophilone Ia(2), Isochromophilone Ib(3), Isochromophilone III(4), epi-isochromophilone III (5), Isochromophilone IV(6), dechloroisochromophilone IV(7), Isochromophilone VIII(8), TL-1-monoAc(9),其中化合物8在30μmol.L-1浓度下对HL-60细胞的抑制率达到97.87%,IC50值为11.81μmol.L-1
英文摘要:
      Objective To study the azaphilones compounds of the epiphytic fungus Penicillium sclerotiorum from the Xisha Islands soft coral sinularia sp., Methods The fermentation extracts of the strains were separated and purified by silica gel column chromatography, thin layer chromatography, Sephadex LH-20 gel column chromatography, MPLC and HPLC. The spectroscopy methods such as NMR and MS were used. The literature data was aligned to identify the structure of the compound; The antitumor activities of the compounds were evaluated by a cytotoxicity experiments. Results Nine azaphilones were isolated from the fungus Penicillium sclerotiorum, namely (+)-Sclerotiorin (1), Isochromophilone Ia (2), Isochromophilone Ib (3), Isochromophilone III (4), epi-isochromophilone III(5), Isochromophilone IV(6), dechloroisochromophilone IV(7), Isochromophilone VIII (8), TL-1-monoAc (9). Compound 8 inhibited HL-60 cells at 30 μmol.L-1by 97.87%. The IC50value is 11.81μmol.L-1.
