Phorbol is widely used in biochemical research, particularly in studies related to cell signaling and cancer. It is known for its ability to activate protein kinase C (PKC), a key enzyme involved in various cellular processes, making it a valuable tool for investigating PKC-mediated pathways. Additionally, phorbol esters, derivatives of phorbol, are utilized to induce tumor promotion in experimental models, aiding in the study of carcinogenesis and tumor development. Its application extends to immunology, where it is used to stimulate immune cell activation and study inflammatory responses. Phorbol's role in these areas has significantly contributed to understanding cellular mechanisms and disease progression.
