Swainsonine is an indolizidine alkaloid. It is a potent inhibitor of Golgi alpha-mannosidase II, an immunomodulator, and a potential chemotherapy drug.[1] As a toxin in locoweed (likely its primary toxin[2]) it also is a significant cause of economic losses in livestock industries, particularly in North America. It was first isolated from Swainsona canescens.[3]
