title: Structures of azaspiracid analogs, azaspiracid-4 and azaspiracid-5, causative toxins of azaspiracid poisoning in Europe.
abstract: Two new analogs of azaspiracid, azaspiracid-4 and azaspiracid-5, isolated from the mussel Mytilus edulis, involved in a newly emerged shellfish poisoning in Europe were determined to be 3-hydroxy-22-demethylazaspiracid and 23-hydroxy-22-demethylazaspiracid, respectively.
