phorbol, particularly 12-O-tetradecanoylphorbol 13-acetate, also
known as phorbol myristate acetate, have been identified as the
potent, highly lipophilic tumor-promoting components in croton
oil. They are potent promoters of skin tumors in vivo and have
been shown to transform cultured fibroblasts and embryonic cells
previously exposed to polycyclic aromatic hydrocarbon carcinogens in vitro. The structure of phorbol, the parent alcohol is
shown below. Phorbol esters also have important effects on leukocytes and on the immune system of the intact animal. There
appears to be a specific receptor for phorbol esters on T cells, a
finding that may account for the selective toxicity of phorbol
esters for T cells. The mechanism of tumor promotion by phorbol
esters is still largely unknown, but findings suggest an initial cell
membrane interaction (often with stimulation of second messenger synthesis and increased protein kinase activity), with subsequent effects on nuclear regulatory events. |
| PHORBOL 12-MYRISTATE 13-ACETATE Usage And Synthesis |
| Description | Phorbol 12-myristate-13-acetate (16561-29-8) activates protein kinase C (10-100 ng/ml)1. May display PKC-independent effects in various cell types2. Warning: Phorbol 12-myristate-13-acetate is a skin irritant. Avoid contact with this compound. | | Chemical Properties | white to off-white solid | | Uses | 4β-Phorbol 12-Myristate 13-Acetate is used in the activation of certain pyruvate kinases as well as protein kinases. | | General Description | White crystals. | | Air & Water Reactions | Practically water insoluble. | | Reactivity Profile | PHORBOL 12-MYRISTATE 13-ACETATE is sensitive to acids and alkalis. . | | Fire Hazard | Flash point data for PHORBOL 12-MYRISTATE 13-ACETATE are not available; however, PHORBOL 12-MYRISTATE 13-ACETATE is probably combustible. | | Biological Activity | Extensively used phorbol ester activator of protein kinase C; tumor promoter. Binds to PKC with a K i value of 2.6 nM as measured by displacement of [ 3 H]phorbol 12,13-dibutyrate binding in rat cortex synaptosomal membranes. | | Biochem/physiol Actions | Cell permeable: yes | | References | 1) Saraiva et al.
