Outline of Final Research Achievements

The search for new anti-trypanosomal natural products from marine organisms was performed. As a result, seventeen new natural products were isolated from marine sponges and dinoflagellates, and the structures of new compounds were elucidated. Three new compounds were analogs of anti-trypanosomal natural products previously found by us. These compounds were isolated to analyze the structure activity relationships of anti-trypanosomal natural products. The detailed investigation about anti-trypanosomal activity of new compounds were currently in progress.
