High-Purity Tumor Promoter & PKC Pathway Activator
≥98% Purity (HPLC-UV validated, λmax 234 nm)
Mechanistic Research Tool: Serves as the core structure for bioactive esters (e.g., PMA) in PKC-dependent carcinogenesis and immunology studies.
Natural Source Integrity: Sourced from Croton tiglium seeds, preserving native diterpenoid activity.
1. Tumor Promotion Research
Acts as a progenitor of tumor-promoting esters (e.g., PMA) in two-stage carcinogenesis models, enabling mechanistic studies of PKC-mediated cell proliferation.
Metabolic Activation: Liver microsomes convert phorbol to active esters in vivo, mimicking endogenous tumor promotion pathways.
2. Pharmacological Synergy
Enhances cytotoxicity of chemotherapeutics (e.g., doxorubicin) in multidrug-resistant cancer lines via PKCα modulation.
