Researchers worry that damage to the oceans could mean some species — and whatever chemicals they produce — will be lost before they’re found

Marc Slattery, a marine biologist by training, looks to sponges and coral as possible sources of drugs. As stationary species in the open ocean, these organisms have developed many chemical defenses to protect themselves. Slattery studies whether those chemicals could protect us, too. Maybe the same compounds that fend off fish could battle viruses, kill bacteria, and even fight cancer.

“These organisms are producing some nasty sorts of chemistry,” Slattery explains. “If you focus on the biotech side of things, there may be a drug in that” — or, he suspects, many.

After a long history of success on land, pharmacognosy — the search for substances in nature that have pharmaceutical potential — is finally getting its sea legs. Slattery, a pharmacognosy professor at the University of Mississippi, is one of the researchers scouring the oceans for cures.

Ocean acidification, warming water temperature and pollution all threaten sensitive corals and the symbiotic species that live on the reefs. Says Michael Lesser, a coral reef biologist at the University of New Hampshire who collaborates with Slattery, “We could lose something that could have great value to us as human beings, and not even know it.”
