Some chemicals produced by marine animals that may be useful in treating human diseases include: A striking feature of this list is that all of the organisms (except the cone snail) are sessile (non-moving) invertebrates. As the authors of the study explain, “bioactivities reported from actinobacterial [natural products] include antibacterial, antifungal, antitumor, anticancer, anti-inflammatory, antiviral, cytotoxic, and immunosuppressive activities.”, Some of the actinobacterial extracts were effective against C. albicans and S. aureus. Drug Source T arget Cellular/Animal Model Effect Ref. What can science tell us about mediums who hear voices? However, there are still very few marine-derived compounds playing a role in the treatment of disease. […] Such compounds proved to have antibacterial, antiviral, antifungal, antimalarial, antitumor, immunosuppressive, and cardiovascular activity.”. Ziconotide is a synthetic version of conotoxin that works as a pain reliever and is 1,000 times more potent than morphine. Of the drugs that scientists test for in the environment, an emerging class of interest is selective serotonin re-uptake inhibitors (SSRIs), commonly prescribed for depression and anxiety disorders. A California startup “bioprospects” for sponges, algae and other organisms whose chemistry may be useful to the world of medicine Most recently, a group of researchers investigated molecules that they had extracted from lampreys — a jawless, parasitic fish with an ancient pedigree. VLRs target the extracellular matrix (ECM), which is a network of molecules that runs between cells. Beyond providing nutritious seafood and food supplements, marketable products, climate control, employment, recreation and aesthetic enjoyment, marine life has long been used to … Among the marine organisms, algae have revealed to be one of the major sources of new compounds of marine origin, including those exhibiting antitumor and cytotoxic potential. Finding new cures happens in steps. It proved so toxic that it was rejected as a therapeutic drug source. There are many good reasons to improve ocean health, but one of the most compelling is to make people healthier too. There are hundreds of other species of cone snail, including the geography cone. People may take it to treat chronic pain that results from conditions such as cancer, stage 3 HIV, and certain neurological disorders. “These chemicals are psychotropic. Title: Anticancer Drugs Discovery and Development from Marine Organisms VOLUME: 9 ISSUE: 16 Author(s):Chiranjib Chakraborty, Chi-Hsin Hsu, Zhi-Hong Wen and Chan-Shing Lin Affiliation:Department of Marine Biotechnology and Resources, College of Marine Science and Division of Marine Biotechnology, Asia-Pacific Ocean Research Center, National Sun Yat-sen University, Kaohisung, Taiwan. However, because ziconotide only works if healthcare professionals deliver it directly into the spinal fluid (intrathecally), they only use it when other therapies have failed or are not viable. However, we are aware that aquatic organisms are especially vulnerable to their effects: many fish and other aquatic species are experiencing increased feminisation as a result of their exposure to birth control pills and other hormonal medications disposed of in the oceans. KH-CB19: C 15 H 13 Cl 2 N 3 O 2 M.W. When dried, this mixture is usually around 16% morphine alkaloid, though some plants have been specially bred to produce up to 26% morphine.  Similarly, a study found that eurysterols A and B, two chemicals from a sponge of the genus Euryspongia, “exhibited antifungal activity against amphotericin B-resistant and wild-type strains of [C. albicans].” They also killed human colon carcinoma cells in the laboratory. Most plankton are microscopic, but some are visible to the naked eye. Competition for space may explain why some of these invertebrates produce anti-cancer agents. The sponge Halichondria okadai is responsible for producing one chemical of note, which researchers have replicated and renamed as eribulin. During the reign of the emperor Fu Hsi, there was a tax on the profits that came from fish-derived medicine. People sometimes refer to this mollusk as the cigarette snail because, following envenomation, you only have enough time to smoke a cigarette before you die. 2018 Sep 14;16(9). The Ocean, which is called the ‘mother of origin of life’, is also the source of structurally unique natural products that are mainly accumulated in living organisms. In fact, the authors of a review on the topic even refer to them as a “drug treasure house.” They write: “Every year, around 5,300 different natural products and new compounds have been isolated from marine sponges. However, there is no question that these ... are unique to the ocean and thus provide opportu- nities for the isolation of unique drugs. Interestingly, according to senior author Dr. Maria de Fátima Carvalho, “seven of the extracts inhibited growth of breast and particularly nerve cell cancers, while having no effect on noncancer cells.”. search of organisms from the marine environment as sources for new drugs. Actinobacteria are particularly interesting to medical researchers. All of these things require active biological molecules. In a living creature, drugs do not always respond in the way that scientists expect. Jumping forward a few thousand years to the 1950s, an organic chemist called Werner Bergmann isolated a number of nucleosides from a Caribbean species of sponge called Cryptotethya crypta. Bioprospecting for Industrial Enzymes and Drug Compounds in an Ancient Submarine Forest, Searching for New Pharmaceutical Drugs from Hydrothermal Vent Animals and Microbes – Submarine Ring of Fire 2012: Northeast Lau Basin, Medicines from the Sea – NOAA Ocean Today, Medicines from the Deep Sea: Exploration of the Gulf of Mexico, Biological Diversity Equals Chemical Diversity–The Search for Better Medicines – Islands in the Stream 2002. As humans heap increasing pressure on marine ecosystems, concerns about the health of our oceans are reaching fever pitch. For example, if a sponge makes a compound that is toxic to predators, or tastes bad, that sponge may be protected from being eaten, and will have an advantage over one that does not produce the compound. Ocean research offers promising new ways to predict disease There are two major approaches to be developed for drug discovery from marine organisms, which includes establishment of new and further development of … To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video. From the antibodies derived from animals to the metabolites obtained from plants, natural products are one of the main sources of compounds for drug discovery and have demonstrated considerable potential in the biomedical field. Meet Dr. Shirley A. Pomponi, Natural Products Biologist – OceanAGE Careers, Subscribe The potential for discovering important new drugs from deep-ocean organisms is high, because most of Earth’s seafloor is still unexplored, and deep-sea explorations routinely find species that have never been seen before.
