2013 Annual Report
Pterostilbene was shown to inhibit progression of prostate cancer in animals. Pterostilbene inhibited the metastasis protein 1 (MTA1), and reduced tumor size more than resveratrol. This study found:.
The biting deterrent effect of a series of fatty acids against the yellow fever mosquito [Aedes (Ae.) aegypti] was investigated, in collaboration with an entomologist at the University of Mississippi. Bioassays on mid-chain length fatty acids showed at 24-h post treatment; lauric acid had a proportion not biting value higher than DEET at low concentrations and a similar value at higher concentrations. Cloth patch assays with human subjects at USDA, ARS, Center for Medical, Agricultural and Veterinary Entomology (CMAVE) showed that the mid-chain length fatty acids were not as effective as DEET against Ae. Aegypti.
Phenolic compounds from cashew nut shell liquid were evaluated for activity against Ae. aegypti larvae, in collaboration with CMAVE. Cardol and cardanol derivatives were active. Neither methylation nor hydrogenation of the compounds improved their activities. Large scale synthesis of a mosquito repellent, with duration of action three times longer than DEET, was performed. Toxicity studies were performed by a private company.
Collaboration with scientists from China and Brazil yielded:.
In collaboration with microbiologists from Brazil, bioactive compounds from fungi associated with macroalgae from Antarctica were surveyed. Penicillium spp. recovered from the endemic species Palmaria decipiens and Monostrama hariotii, respectively, yielded extracts with high and selective antifungal and/or trypanocidal activities. Extracts of the phytopathogenic fungi Fomitopsis and Epicoccum species were antifungal and phytotoxic. Acyl derivatives of glucinol were as active against the fish bacteria Flavobacterium columnare and Streptococcus iniae as a drug control.
