Phorbol esters are a class of chemical compounds found in a variety of plants, particularly in the families Euphorbiaceae and Thymelaeaceae. [ 1 ] [ 2 ] Chemically, they are ester derivatives of the tetracyclic diterpenoid phorbol .
Phorbol is a natural product found in many plants, especially those of the Euphorbiaceae and Thymelaeaceae families. [10] [11] Phorbol is the active constituent of the highly toxic New World tropical manchineel or beach apple, Hippomane mancinella. [12] It is very soluble in most polar organic solvents, as well as in water. In the manchineel ...
Mezerein is a toxic diterpene ester found in the sap of Daphne mezereum and related plants. Plants of the genera Euphorbiaceae and Thymelaeaceae possess a wide variety of different phorbol esters, which share the capacity of mimicking diacylglycerol (DAG) and thus activating different isoforms of protein kinase C. Mezerein was first isolated in ...
This latex is extremely toxic due to its skin irritant and carcinogenic diterpene derivatives, mainly phorbol esters. [11] In addition to irritation of the skin and mucous membranes, E. candelabrum latex may cause blindness if brought into contact with the eyes. [5] Various components of E. candelabrum plants can be

Euphorbia helioscopia contains toxic diterpenes [10] and diterpenoids [11] and phorbol esters. These substances are the major skin irritants found in the plant. [12] The plant is considered poisonous when eaten raw. Nausea, allergic reactions, skin irritation, vomiting may occur after eating. [13] A number of tannins can be found in E ...
This past week I found hundreds of these plants more than one foot tall before April 1! Know thy enemy: What to know about poison hemlock. Poison hemlock is a biennial, which means that it spends ...
Mice painted only with croton oil hadn’t developed tumors. Croton oil is the source of the chemical compound phorbol. [7] Tumor promotion activity was traced to phorbol esters present in croton oil. [8] Pure phorbol 12-myristate 13-acetate, which is found in croton oil, is widely used in laboratory research to induce tumor development.
