Description
Kansuiphorin B is a tetracyclic diterpenoid that is 6,7-epoxy-13-hydroxyingenol in which the hydroxy groups at positions 3, 13 and 20 are esterified by 2,3-dimethylbutyric acid, lauric acid and palmitic acid. Isolated from the roots of Euphorbia kansui, it exhibits anti-cancerous activity. It has a role as a metabolite and an antineoplastic agent. It is a cyclic terpene ketone, a fatty acid ester, a tetracyclic diterpenoid and a dodecanoate ester. It is functionally related to a 2,3-dimethylbutyric acid, an ingenol, a dodecanoic acid and a hexadecanoic acid.
Kansuiphorin B has been reported in Euphorbia kansui with data available.
