Diosgenin

Diosgenin is a sapogenin that is spirostan which is substituted by a hydroxy group at the 3beta position, contains a double bond at the 5-6 position, and has R- configuration at position 25. A natural product found in Dioscorea (wild yam) species, it is used as the starting point for the commercial synthesis of a number of steroids, including cortisone, pregnenolone and progesterone. It has a role as an antiviral agent, a metabolite, an antineoplastic agent and an apoptosis inducer. It is a sapogenin, a 3beta-sterol, a hexacyclic triterpenoid and a spiroketal. It derives from a hydride of a spirostan. — ChEBI
