4105 Gymnodimine Gymnodimine is found in mollusks. Gymnodimine is isolated from New Zealand oysters (Tiostrea chilensis) and the dinoflagellate Gymnodinium cf. mikimotoi. 173792-58-0 10436276 C32H45NO4 White powder. Gymnodimine exerts its toxic effects via binding to nicotinic acetylcholine receptors with picomolar affinities with no sign of apparent reversibility in short time frames. The toxicity of gymnodimine has been attributed, at least in part, to the imine functionality as its reduction leads to a non-toxic derivative. Gymnodimine and 13-desmethyl spirolide C bound to acetylcholine binding proteins. (A15418) No indication of carcinogenicity to humans (not listed by IARC). Gymnodimine is found in mollusks.
