Phorbol esters

Chemical structure of 12-O-tetradecanoylphorbol-13-acetate, a phorbol ester

Phorbol esters are a class of chemical compounds found in a variety of plants, particularly in the Euphorbiaceae and Thymelaeaceae families.[1] Chemically, they are ester derivatives of the tetracyclic diterpenoid phorbol.

Biological activity

Phorbol esters are known for their ability to promote tumors. In particular, 12-O-tetradecanoylphorbol-13-acetate (TPA) is used as a biomedical research tool in models of carcinogenesis.[2][3]

Plants that contain phorbol esters are often poisonous.[3]
