Protein kinase C (PKC) is a phorbol ester receptor. [2] [3] Phorbol esters can stimulate PKC in a similar way to diglycerides. [2] [3] Phorbol esters are known for their ability to promote tumors. [2] In particular, 12-O-tetradecanoylphorbol-13-acetate (TPA) is used as a biomedical research tool in models of carcinogenesis. [4] [5] Plants that ...
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 ...
12-O-Tetradecanoylphorbol-13-acetate (TPA), also commonly known as tetradecanoylphorbol acetate, tetradecanoyl phorbol acetate, and phorbol 12-myristate 13-acetate (PMA) is a diester of phorbol. It is a potent tumor promoter often employed in biomedical research to activate the signal transduction enzyme protein kinase C (PKC).
C1 domain (also known as phorbol esters/diacylglycerol binding domain) binds an important secondary messenger diacylglycerol (DAG), as well as the analogous phorbol esters. [1] Phorbol esters can directly stimulate protein kinase C, PKC. Phorbol esters (such as PMA) are analogues of DAG and potent tumor promoters that cause a variety of ...

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.

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 ...
