A saturated derivative of sphingosine. As an inhibitor of protein kinase C (PKC), safingol competitively binds to the regulatory phorbol-binding domain of PKC, a kinase involved in tumorigenesis. This agent has been shown to act synergistically with other chemotherapeutic agents and may potentiate chemotherapy drug-induced apoptosis in vitro and in vivo. Check for \'https://www.cancer.gov/about-cancer/treatment/clinical-trials/intervention/C1568\' active clinical trials using this agent.
