  Synthesis of the New Mannosidase Inhibitors, Diversity-Oriented 5-Substituted Swainsonine Analogues, via Stereoselective Mannich Reaction

  摘要：

  5alpha-Substituted swainsonine analogues were synthesized by Mannich reaction of an in situ generated (-)-swainsonine iminium ion intermediate. 5alpha-Substituted swainsonine analogues were epimerized to their 5beta-isomers in protic solvent.

  Reaching for specificity: X‐ray crystallographic data indicates potent 5α‐substituted swainsonine analogues bind in a novel fashion to Golgi α‐mannosidase II by inserting in a water cluster and by forming new hydrophobic interactions. These offer the potential of being extended into the GlcNAc binding site to improve selectivity and reduce harmful side effects.

  达到特异性： X射线晶体学数据表明有效的5α-取代的swainsonine类似物通过插入水簇中并形成新的疏水性相互作用，以新颖的方式与高尔基α-甘露糖苷酶II结合。这些提供了被扩展到GlcNAc结合位点以改善选择性和减少有害副作用的潜力。
