An improved procedure based on centrifugation at 37,000 g has been developed for isolating the antineoplastic glycoprotein strongylostatin 1 from Strongylo-centrotus droebachiensis (Müller). The green sea urchin has also been found to contain a second protein anticancer constituent designated strongylostatin 2. Treatment of the murine P3S8 lymphocytic leukemia with strongylostatin 2 resulted in 39-42% life extension at a dose of 4.5 mg/'kg.In the marine phylum Echinodermata the subphylum Echinozoa contains the free-living echinoderms without arms such as the nearly eight hundred sea urchins (Echinoidea class). Generally the tube feet and movable spines of these animals are used for locomotion. The ventral side contains the mouth ringed with five teeth (Aristotle's lantern) and the anus is on the upper side. The sea urchins are bottom-living and feed on both plants and animals. The broad ranging (circumpolar) green urchin Strongylocentrotus droebachiensis Müller (Echinocea superorder, Strongylocentrotidae family) bears glandular-type (2) pedicellariae venom glands which assist in feeding and defense by immobilizing prey (3). 2 For example, treatment with a solution of zinc sulfate evokes an escape response similar to that seen when the urchin is attacked by the predatory starfish Marthasterias glacialis; the globiferous pedicellariae are raised with open jaws (4).
