Potent and selective inhibitor of α-mannosidase I1,2.Inhibits the conversion of high mannose to complex oligosaccharides3. Attenuates tunicamycin-, thapsigargin- and Beta Amyloid1-42-induced ER stress dependent neuronal cell death and protects primary cultured mouse cortical neurons from Beta Amyloid 1-42 toxicity4. Increases titers (4 fold) in the production of lentivirus vectors with enhanced efficiency in targeting dendritic cells5,6.
