Research Abstract

In order to explore the possibility of discovering new compounds with biomedical importance from deep-sea sponges, we collected 78 samples at Shinsone, near Oshima Island and examined the biological activities of their extracts. More than 70% of the extracts exhibited either cytotoxic, antimicrobial, or enzyme inhibitory activity, demonstrating the importance of deep-sea sponges in natural products drug discovery. We have isolated the following compounds from the collected specimens.
1.Theopederin K from Discodermia japonica
2.Shinsonefuran from Stoeba extensa
3.Novel macrolides from Poecillastra sp.
Isolation of cytotoxic constituents from another deep-sea sponge collected off Heda, Izu, is in progress.
