They mimic diacylglycerols, glycerol derivatives in which two hydroxyl groups have reacted with fatty acids to form esters. The most common and potent phorbol ester is 12-O-tetradecanoylphorbol-13-acetate (TPA), also called phorbol-12-myristate-13-acetate (PMA), which is used as a biomedical research tool in contexts such as models of ...
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 ...

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 ...
Phorbol 12,13-dibutyrate (PDBu) is a phorbol ester which is one of the constituents of croton oil. As an activator of protein kinase C, it is a weak tumor promoter compared to 12-O-tetradecanoylphorbol-13-acetate. [1] PDBu is widely used as a chemical reagent because of its solubility in water and other organic solvents.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

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).
