Glycoyessotoxin a, a new yessotoxin derivative from cultures of Protoceratium reticulatum.
The dinoflagellate Protoceratium reticulatum produces toxins of the yessotoxin group currently included in the diarrhetic shellfish poisoning class. In this paper we report on the isolation and structural elucidation of a 32-arabinoside of yessotoxin, G-YTXA (2), obtained from laboratory cultures of P. reticulatum (strain GG1AM) that possesses a pentose unit, beta-arabinofuranose, as a side chain.
