Castanospermine is an indolizidine alkaloid first isolated from the seeds of Castanospermum australe.[3] It is a potent inhibitor of some glucosidase enzymes[4] and has antiviral activity in vitro and in mouse models.[5]

The castanospermine derivative celgosivir is an antiviral drug candidate currently in development for possible use in treating hepatitis C virus (HCV) infection.[6]
