Marine organisms represent an enormous, essentially unexploited, resou
rce of natural products. Globally, the race to develop marine-derived
drugs is well under way with many pharmaceutical companies positioning
themselves to reap large profits by the exploitation of the ocean's r
ich chemical diversity. Targeted strategies, often in combination with
high-throughput screening, are being employed in this hunt for novel
pharmacotherapeutic agents. David de Vries and Phil Beart examine the
potential, problems and technologies of an international pharmaceutica
l search that has important ethical considerations.
