N2 - Two new analogs of the human lethal toxin polycavernoside A, polycavernoside C and C2 (0.1-0.2 mg for each), were isolated from the red alga, Gracilaria edulis. The relative stereostructure of polycavernoside C and the absolute structure of polycavernoside C2 were determined by spectroscopic analysis and synthesis of the model of their aglycon.
