title: DTX5c, a new OA sulphate ester derivative from cultures of Prorocentrum belizeanum.
abstract: Prorocentrum belizeanum is a dinoflagellate known for its okadaic acid (OA) and dinophysitoxins (DTXs) production, both OA and DTX are polyether toxins of the Diarrhetic Shellfish Poisoning (DSP) group. We have recently published the isolation of a new diol-ester of okadaic acid from cultures of P. belizeanum. On this occasion we present a new sulphated water-soluble derivative, DTX-5c, isolated from this microalga, whose structure was established on the basis of its spectroscopical data.
