Fuscusine, a Tetrahydroisoquinoline Alkaloid from the Seastar<i>Perknaster Fuscus Antarcticus</i>

Abstract

Abstract The body wall of the Antarctic seastar Perknaster fuscus antarcticus contains fuscusine (2), the structure of which was elucidated by interpretation of spectral data. Fuscusine was detected as a “false positive” in the E. coli K-12 SOS chromotest bioassay.
