Structure and fluorometric HPLC determination of 1-desulfoyessotoxin, a new yessotoxin analog isolated from mussels from Norway.

Abstract

A new analog of yessotoxin, 1-desulfoyessotoxin, was isolated from the digestive glands of mussels growing in the Sognefjord, Norway. Its structure was determined by NMR and negative ion CID MS/MS experiments. 1-Desulfoyessotoxin can be detected by the fluorometric HPLC method analogous with other yessotoxins.
