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.
