An indolizidine alkaloid (swainsonine) was isolated from the plant Swainsona canescens. Swainsonine is a specific and potent inhibitor of alpha-mannosidase (EC 22.214.171.124) and when administered to animals produces a phenocopy of the genetically based lysosomal storage disease, mannosidosis. Evidence is presented to suggest that swainsonine is a reversible active site-directed inhibitor of lysosomal alpha-mannosidase.
