The major toxin involved in the diarrhetic shellfish poisoning was isolated from the hepatopancreas of the mussel Mytilus edulis and was named dinophysistoxin-1. It was obtained as a colorless solid: mp. 134°C, [d]20D 28°, LD99 160μg/kg (ip to mouse). Comparison of the toxin by various spectrometries with okadaic acid isolated from the marine dinoflagellate Prorocentrum lima established that dinophysistoxin-1 is 35S-methyl okadaic acid C45H70O13. Gas chromatographic analysis evidenced the presen

The species-specific partnership between the sea anemone and anemone fish in many parts of the Indo-Pacific region is a well-known phenomenon. Chemicals secreted by the sea anemone to elicit symbiotic behavior of the fish have been studied for two host-guest pairs, Radianthus kuekenthali (sea anemone)-Amphiprion perideraion (anemone fish) and Stoichactis kenti-A. ocellaris. A new pyridinium compound, amphikuemin, which induces characteristic attracted swimming (toward the chemical stimulus) in A
