biological activities. Here, we report the synthesis of two representative congeners, namely, pervicoside B and C, starting from lanosterol with the longest linear sequence of both 34 steps and in 0.3% overall yields. The flexible synthetic approach has enabled us to expeditiously prepare 16 analogues for preliminary studies on the key structural features influencing their antiproliferative activities against
甾烷糖苷是海参的特征代谢产物,具有多种生物活性。在这里,我们报告了两种代表性同类物的合成,即pervicoside B和C,它是从羊毛甾醇开始的,其线性最长的序列均为34个步骤,总产率为0.3%。灵活的合成方法使我们能够迅速制备出16种类似物,以初步研究影响其抗肿瘤细胞增殖活性的关键结构特征。发现简化的二糖与天然四糖一样有效,可用作未来研究的先导。
