The cancer cell line bioassay-guided separation of an extract from the marine mollusk Turbo stenogyrus led to the isolation of four new cerebrosides designated turbostatins 1-4 (1-4). The structure of each glycolipid was determined by interpreting results of a series of HR-APCI-MS and NMR (1D and 2D) spectral analyses. All four turbostatins exhibited significant (GI50 0.15-2.6 microg/mL) cancer cell growth inhibition against the murine P388 lymphocytic leukemia and a panel of human cancer cell lines.
对海洋软体动物扁玉螺提取物进行癌细胞系生物测定导向分离,得到了四种新的脑苷脂,命名为扁玉螺素1 - 4(1 - 4)。通过解读一系列高分辨大气压化学电离质谱(HR - APCI - MS)和核磁共振(1D和2D)光谱分析结果,确定了每种糖脂的结构。所有四种扁玉螺素对小鼠P388淋巴细胞白血病和一组人类癌细胞系均表现出显著的(半数抑制浓度GI50为0.15 - 2.6微克/毫升)癌细胞生长抑制作用。
