L’océan, nouvelle frontière de la médecine
Brest. France.July 2005. Portrait of Dominique RIBOLA, engineer in chemistry and doctor of engineering at « Ecole Centrale of Paris ». With his own companie « SEADEV », Dominique RIBOLA is developping innovative molecules and production processes from the bacteria collected in the deepest parts of the ocean. Working with IFREMER, (French research center on marine life) the results are starting to fabricate entirely biodegradable plastic, effective oral hygiene ingredients, highly cosmetic products, and new substances of pharmacological interest. Dominique RIBOLA has opened fascinating new portals into the world of biotechnologie and biomedicine.There is no end to the discoveries
Cancers, malaria, infection
virale, maladie d’Alzheimer, arthrite… Le potentiel de l’océan pour produire de
nouveaux médicaments afin de traiter ces maladies n’a jamais offert autant de
possibilités. La faune et la flore marines contiennent des secrets biochimiques
qui peuvent aider à comprendre les maladies et à la production de traitements.
Les bactéries des grandes profondeurs contiennent des nouvelles molécules exploitables pour la biomédecine ou la
biotechnologie. Les recherches montrent que le potentiel pharmaceutique des
organismes marins peut dépasser le potentiel terrestre actuel.

Dr William FENICAL, Professor of Oceanography holding a molecular model of a new anticancer agent produced by deep ocean bacteria : the marinomycin A. Marinomycin A is a potent inhibitor of cancer cell growth and shows an impressive selectivity toward melanoma. This picture was done near the University of California, in San Diego in la Jolla, (USA) where William FENICAL is Director of the Center for Marine Biotechnology and Biomedicine (CMBB).
The ocean is the next great biomedical frontier
Cancers, malaria, viral infection, Alzheimer
disease, arthritis… The potential of the ocean to provide new drugs to treat
human illnesses has never offered greater promise. Marine plants and animals
contain biochemical secrets which can provide new insights and understanding of
human diseases and their treatment. Bacteria from the depths of the sea provide
new molecules for biomedecine and biotechnologie. Research now indicates that
the pharmaceutical potential of natural compounds from marine organisms may
surpass the potential of traditional terrestrial drug sources ! There is no end
to the discoveries…

Dr William FENICAL, Professor of Oceanography with a sand/mud sample from the coast of La Jolla in San Diego in the USA . The idea is to indicate how promising the new actinomycete bacteria from this source. More than 13 new genera of these bacteria have been found in marine muds, strongly indicating a huge diversity of new antibiotics and anti-tumor drugs can be developed. William FENICAL is Director of the Center for Marine Biotechnology and Biomedicine (CMBB). at the SCRIPPS institution of Oceanography.

At the SCRIPPS Institution of Oceanography in San Diego (USA). Photo of unicellular actinomycete growing on agar media. It is a new genus of bacteria. It was isolated from marine sediment collected during a research expedition in the Republic of Palau in Pacific. The marine derived actinomycete is most closely related to Microccus luteus. These strains were only recently isolated from marine sediments and are currently having their chemical diversity studied. In addition to looking for never before seen chemical compounds,, scientists are also testing to see whether the strains produce chemical compounds that have anti-cancer, antibiotic and/or anti-fungal properties.

Dr Gutierrez : « The clinical results show that this newly discovered molecule has a huge potential for regenerating bone and skin loss associated with age, including osteoporosis and arthritis. »
This molecule was discovered in the algae called « Padina pavonica ». It is a new core symmetrical structure linked with the steroid family.
ICP and the French research institute Texinfine have now established a joint research facility and production unit to produce the molecule on an industrial scale, for pharmatceutical and nutritional products to help with the regeneration of bone and skin.

He discovered more than 150 species of sponge. The scientists have identified molecules which, in vitro, can prevent proteins vital to the parasite of Malaria from functionning. They come from marine sponge. In the back, photo of a sponge- alcyonnaires. Sponges, often plagued by parasitical bacteria, produce defensive chemical substances.

« The ocean may be the last, best hope of earth » Roger Revelle
The spiny starfish (Marthasterias Glacialis) living in the English ChannelÕs waters produces a surprising molecule against cancer. It was Dr. Laurent Meijer of CNRS of Roscof, France who discovered the ÒRoscovotineÓ. ItÕs a molecule used against breast and lung cancers. Therapeutic tests are underway. In blocking cancerous cells without affecting healthy ones, the ÒRoscovotine is a new potential chemical therapeutic weapon against cancer.

Abalone. (Photo taken in an aquarium) Researchers are studying the molecules that regulate sperm and egg interactions in sea urchins and abalones to understand better how human cells work. Deciphering sperm and egg interactions at the cellular level in lower animals can unlock mysteries of cell interaction in higher animals. Such discoveries may be used to explain human disease processes with the hope of increasing our ability to prevent them. Understanding how sperm cells penetrate egg cells also can help scientists understand how disease-causing cells invade normal cells.

Interactions of all kinds, including chemical interactions, are a fundamental characteristic of nature. In the marine environment, interactions between organisms are mainly mediated by chemical communication. Although the natural function of most natural products remains uninvestigated, many of them have been demonstrated to serve as defenses against predators or competitors. Investigations of biological and chemical ecological phenomena in the marine world contribute to a better understanding of marine habitats and also provide a more founded basis regarding the search for pharmaceutically useful marine natural products.
