Abstract

Background/Aim: Dimethylsulfoniopropionate (DMSP) has been intensively studied in bacteria, plankton, algae and salt-resistant plants to investigate its metabolism and fate in the atmosphere. However, its effects on diseased terrestrial animals have not yet been examined. We have found that DMSP exerts a great healing effect for a variety of inflammatory disorders in rodents. In the present study, effects of single and high concentration of DMSP on terrible Ehrlich ascites carcinoma (EAC) bearing-mice with unavoidable-rapid death were examined. Results: We found that high concentration of DMSP completely suppresses acute EAC, which has never been eradicated, and accumulates large amounts of activated macrophages with no inflammation on various viscera in the peritoneal cavity of normal mice. Conclusion: These results show that DMSP is a new and potent anticancer compound with no side-effects, most likely playing a vital role for cancer immune therapy.
