WebPinnatoxins and α-conotoxins represent two such groups of marine toxins. While pinnatoxins are macrocyclic small molecules and α-conotoxins are peptidic toxins, both act as potent and selective nicotinic receptor antagonist toxins. As such, both toxin groups can be utilized to study different aspects of nicotinic receptor structure and function. WebJul 13, 2011 · Published 13 July 2011. Biology, Chemistry.

Pinnatoxins are paralytic chemical compounds that inhibit neuronal and muscle-type nicotinic acetylcholine receptors. Although first discovered in shellfish, they are produced by the peridinoid dinoflagellate Vulcanodinium rugosum. Eight subtypes, designated pinnatoxin A-H, have been described.
