resulted in the identification of three new fatty acid esters, named calopusins A-C (1-3), along with two known fatty acid methyl esters (4-5). These new compounds are structurally unique fatty acid esters with a 2,3-butanediol moiety. Their structures were elucidated through 1D- and 2D-NMR spectroscopic data and GC-MS analysis as well as a modified Mosher's method. The new compounds 1-3 showed significant
对韩国野生蘑菇牛肝菌的 MeOH 提取物进行生物测定引导的分馏和化学研究,鉴定了三种新的脂肪酸酯,命名为 calopusins AC (1-3),以及两种已知的脂肪酸甲酯 (4- 5)。这些新化合物是具有 2,3-丁二醇部分的结构独特的脂肪酸酯。通过一维和二维核磁共振光谱数据和 GC-MS 分析以及改进的 Mosher 方法阐明了它们的结构。新化合物 1-3 对所测试癌细胞系的增殖显示出显着的抑制活性,IC(50) 值在 2.77-12.51 muM 范围内。
