Outline of Final Research Achievements

Marine sponges are an important source of structurally diverse and biologically active natural products, several of which have inspired the development of therapeutic agents. In this project, 1500 extracts of marine sponges collected in Japanese shallow-sea or deep-sea were analyzed by LC-MS followed by cluster analyses to reveal their chemical profiles. Based on the chemical profiles, we isolated three cytotoxic peptides and three cytotoxic glycolipids from two different marine sponges. Their structures were determined by a combination of chemical methods and spectroscopic data analyses.
