Outline of Final Research Achievements

Marine organisms have some different systems of metabolism and physiological functions from the living thing on the ground. We extract the bioactive substances from them and isolate the substances with the strong antitumor activity for the index of the cytotoxicity against cancer cells. We aim not only to analyze the antitumor effect for oral squamous cell carcinoma cells but also apply them to the novel antitumor agents against oral cancer. Marine organisms from both adjacent Japanese sea and adjacent Indonesian sea are collected and freeze-dried. The extracted compounds are investigated their activity by cytotoxic assay for cancer cells and are purified.The novel bioactive substances are investigated with the toxicity for the human iPS cells which are differentiated into some important organic cells under the serum free culture.
