Mycale hentscheli

Peloruside A (31), which is a 16-membered, highly oxidized macrolide from the sponge Mycale hentscheli, induces tubulin polymerization (2). 13-Deoxytedanolide (32) isolated from Japanese sponges of the genus Mycale shows promising antitumor activity. It inhibits protein synthesis by binding to a 70 S large subunit of eukaryotic ribosome (17).
