中文摘要: |
综合运用正、反相硅胶柱层析、薄层层析以及半制备HPLC等多种色谱方法对海洋真
菌Eutypella sp. F0219的乙酸乙酯提取物进行系统分离纯化,获得8个细胞松弛素类化合物(1~8)。
经 一 维 核 磁 共 振 波 谱 数 据 、质 谱 以 及 X- 射 线 单 晶 衍 射 方 法 等 确 定 这 些 化 合 物 分 别 为
phenochalasin A (1),scoparasin D (2),phenochalasin B (3),cytochalasin Z26(4),cytochalasin Z24
(5),[12]-cytochalasin (6),cytochalasin Z25(7)和 cytochalasin Z27(8)。通过 CCK-8 实验评价上述
化合物在非小细胞肺癌NCI-H1299细胞的增殖影响,筛选结果表明化合物2表现出中等的抗肿瘤
活性,IC50值为(5.1±0.25)μmol/L。本研究首次报道了化合物phenochalasin A (1)的X-射线单晶
结构。 |
英文摘要: |
Eight cytochalasins were isolated from the ethyl acetate extract of the marine-derived fungus Eutypella sp.
F0219 by applying silica gel and C18 revised-phase column chromatography, TLC, and semi-preparative HPLC methods.
On the basis of 1D-NMR, ESI-MS, and single-crystal X-ray diffraction crystallography, the structures of these compounds
were elucidated as phenochalasin A (1),scoparasin D (2),phenochalasin B (3),cytochalasin Z26 (4),cytochalasin Z24 (5),[12]-
cytochalasin (6),cytochalasin Z25 (7),cytochalasin Z27 (8), respectively. These compounds were evaluated for cytotoxic activi‑
ties against NCI-H1299 cell line by the assay of CCK-8. Compound 2 exhibited moderate cytotoxicity with IC50 value of
(5.1 ± 0.25) μmol/L. In addition, this is the first report of the X-ray structure of phenochalasin A (1). |
