title: Isolation of geodiatoxins 2-4 from the marine sponge Geodia mesotriaena.
abstract: 1. In a previous study of the marine sponge Geodia mesotriaena von Lendenfeld for antineoplastic constituents, evidence was obtained for the presence of several toxins and geodiatoxin 1 was isolated. 2. Further separations guided by bioassay using CDF1 mice have led to the isolation of three additional chromoprotein toxins lethal at 8 mg/kg.
