Nemertelline is a neurotoxic tetra-pyridine compound originally found in the marine ribbon worm Amphiporus angulatus.^[1] These worms produce a variety of toxins which are used both in hunting their prey and in defending themselves from predators.^[2] Interest in potential application of this compound as an antifouling agent for boats and other marine installations has led to attempts to produce it synthetically by convenient routes.^[3] Its toxicity is similar to nicotine in crustaceans but has no mammalian toxicity. It is similar to nicotelline in structure.^[4]
