Isolation of bioactive compounds from sharks.

Robert Langer
30 pp.

This report details the investigation of an extract from shark cartilage as a potential cancer treatment. Researchers believe one strategy for designing a cancer treatment is to find an inhibitor of the growth of blood vessels that feed tumors. An extract from calf cartilage inhibits blood vessel growth, but it is difficult to get enough extract from calves for extensive experiments. Unlike bone-rich mammalian skeletons, shark skeletons are almost entirely cartilage. Not only can the researchers obtain more cartilage from shark than from calf, but shark cartilage is a richer source of the blood vessel growth-inhibiting extract.
