What is (+)-Dioscin?

Plain description, key identifiers and synonyms

Dioscin is a spirostanyl glycoside that consists of the trisaccharide alpha-L-Rha-(14)-[alpha-L-Rha-(12)]-beta-D-Glc attached to position 3 of diosgenin via a glycosidic linkage. It has a role as an antiviral agent, a metabolite, an antineoplastic agent, an antifungal agent, an EC 1.14.18.1 (tyrosinase) inhibitor, a hepatoprotective agent, an anti-inflammatory agent and an apoptosis inducer. It is a spirostanyl glycoside, a trisaccharide derivative, a hexacyclic triterpenoid and a spiroketal. It is functionally related to a diosgenin. It derives from a hydride of a spirostan.
