An Antarctic collection of Latrunculia apicalis contained as its major secondary metabolite the pigment discorhabdin C as well as a previously unreported pigment, discorhabdin G. Discorhabdin alkaloids have a variety of pharmacological and ecological bioactivities, including the mediation of interactions with the potential predator Perknaster fuscus, a spongivorous sea star. © 1995, American Chemical Society.
