Scientists have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed near Fiji in the South Pacific.
The research team, led by Georgia Institute of Technology Professor of Biology Mark Hay, says some of the natural compounds indicate the potential to kill cancer cells, bacteria and the HIV virus. And scientists say two of the compounds exhibit anti-bacterial activity towards antibiotic-resistant Staphylococcus aureus.
The compound isolated in the greatest abundance -- named bromophycolide A -- killed human tumor cells by inducing apoptosis, or programmed cell death -- a mechanism that is promising for development of new anti-cancer drugs.
The findings on three of these compounds -- called diterpene-benzoate natural products -- are reported in the Oct. 12 online issue of the American Chemical Society journal Organic Letters. Information on the other compounds will be published at a later date.
The research was primarily funded by the Fogarty International Center at the National Institutes of Health.

Golden Nanorods for Medical Applications
(PhysOrg.com) -- Gold nanoparticles are under consideration for a number of biomedical applications, such as tumor treatment. A German-American research team at Carnegie Mellon University in Pittsburgh, Hunter College in New York, and the RWTH Aachen has now developed a new method for the production of nanoscopic gold rods. In contrast to previous methods, they have achieved this without the use of cytotoxic additives. As they report in the journal
Angewandte Chemie, the synthesis is not carried out in water, but in an ionic liquid, a “liquid salt”.

Sulfur in marine archaeological shipwrecks -- the 'hull story' gives a sour aftertaste
Advanced chemical analyses reveal that, with the help of smart scavenging bacteria, sulfur and iron compounds accumulated in the timbers of the Swedish warship Vasa during her 333 years on the seabed of the Stockholm harbour. Contact with oxygen, in conjunction with the high humidity of the museum environment, causes these contaminants to produce sulfuric acid, according to a new doctoral thesis in chemistry from Stockholm University.
