42,43,44,45,46,47,55-Heptanor-41-oxohomoyessotoxin, a new biotoxin from mussels of the northern Adriatic sea.
The diarrhetic shellfish toxin composition in the digestive glands of mussels from the northern Adriatic sea was investigated. Along with known yessotoxins, identified by comparison of their chromatographic and spectral properties with those reported in the literature, we isolated a new analogue of yessotoxin, 42,43,44,45,46,47,55-heptanor-41-oxohomoyessotoxin, 1. Its structure was determined by (1)H NMR spectroscopy and mass spectrometry.
