New Pyridyl and Dihydroisoquinoline Alkaloids Isolated from the Chevron Nemertean Amphiporus angulatus
Nemertean worms perdieme lingerie contain toxins that are used to paralyze their prey and to deter potential predators.Hoplonemerteans often contain pyridyl alkaloids like anabaseine that act through nicotinic acetylcholine receptors and crustacean chemoreceptors.The chemical reactivity of anabaseine, the first nemertean alkaloid to be identified,
