| Hazard Information | Back Directory | [Description]
Glucosidases catalyze the cleavage of individual glucosyl residues from various glycoconjugates, including complex carbohydrates and glycoproteins. Castanospermine is an inhibitor of both α- and β-glucosidases, inhibiting lysosomal and neutral α-glucosidases with Ki values of 0.1 and 10 μM, respectively, and lysosomal and cytosolic β-glucosidases with Ki values of 7 and 40 μM, respectively.1 It is effective both in vitro and in vivo.2,3 Through its effects on glucosidases, castanospermine blocks N-linked glycosylation during post-translational modification of proteins, affecting protein trafficking and cell functions that are dependent on glycosylation, including angiogenesis.3,4 Castanospermine also interferes with viral replication and infection that is dependent on glucosidase activity.5,6,7 | [Chemical Properties]

Castanospermine is a plant alkaloid shown to be a potent inhibitor of lysosomal a-or beta- glucosidase. It also inhibits mammalian glucosidase 1 and beta-mannosidase from sweet almonds and fungal beta-xylosidase. | [Uses]
Castanospermine, is used as a glycosidase inhibitor and antiinflammatory agent.castanospermine is used to inhibit syncytium formation between HIV-infected and CD4-expressing cells and may also interfere with infectivity. It has also been demonstrated that this agent inhibits inflammation at the level of leukocyte extravasation in rat models of experimental adjuvant-induced arthritis and autoimmune encephalomyelitis. Castanospermine is an inhibitor of Glucosidase I, Maltase-glucoamylase, and MANBA. Potent inhibitor of α- and β-glucosidases, especially glucosidase l (required for glucoprotein processing by transfer of mannose and glucose from asparagine-linked lipids). Inhibits HIV syncytium formation and replication. | [Definition]
ChEBI: Castanospermine is a tetrahydroxyindolizidine alkaloid that consists of octahydroindolizine having four hydroxy substituents located at positions 1, 6, 7 and 8 (the 1S,6S,7R,8R,8aR-diastereomer). It has a role as a metabolite, an anti-HIV-1 agent, an anti-inflammatory agent and an EC 3.2.1.* (glycosidase) inhibitor. | [Biological Activity]
Potent inhibitor of α - and β -glucosidases, especially glucosidase l (required for glucoprotein processing by transfer of mannose and glucose from asparagine-linked lipids). Inhibits HIV syncytium formation and replication. | [storage]
