Swainsonine | Glycosidase inhibitor

Swainsonine (72741-87-8) is a naturally occurring alkaloidal toxin found in locoweed. Inhibits the biosynthesis of complex glycoproteins by inhibition of Golgi mannosidase II (IC50 = 0.2 mM).1 Inhibits growth and potentiates the cytotoxic effect of taxol in hepatocellular carcinoma in vivo.2 Induces apoptosis in a variety of cell types including cerebral cortical neurons.3 Impairs adult neurogenesis and spatial learning and memory.4  Abrogation of complex glycosylation by swainsonine results in strain-and cell-specific inhibition of prion replication.5 Induces lysosomal storage disease in farm animals.6
