Saponins exhibit multiple biological and pharmacological activities, and the sugar moiety of saponins is known to play a crucial role in bioactivity. In this report, we focus on the synthesis and evaluation of saponins with all-nitrogenated sugar (ANS), in which all oxygen atoms are replaced with nitrogen atoms. OSW-1 derivative-, cholesterol-, and diosgenin-ANS glycosides are synthesized by glycosylation
皂苷具有多种生物和药理活性,已知皂苷的糖部分在生物活性中发挥着至关重要的作用。在本报告中,我们重点关注全氮糖皂苷(ANS)的合成和评价,其中所有氧原子都被氮原子取代。OSW-1 衍生物、胆固醇和薯蓣皂苷元 ANS 糖苷是在 TMSOTf 存在下通过 ANS 糖基化合成的。因此,具有 ANS 的 OSW-1 模拟物表现出良好的细胞毒活性 (IC 50 = 7.31 μM) 并诱导细胞凋亡。
