Showcase Features Research Using Natural Products

June 9, 2016 | Ten projects highlighting the use of natural products in medical research were on display June 1 at the latest Showcase of Medical Discoveries wine-and-cheese reception hosted by the UAMS College of Medicine and vice chancellor of research. The event was the 14th reception in a series created to foster communication and collaboration among UAMS investigators and clinicians. Participants included faculty members, student trainees, postdoctoral researchers, research staff and other guests.

“Natural products from plants and animals are a rich source for novel drugs that can be used to treat and identify mechanisms underlying human disease. Through this event, we hope to connect UAMS researchers with diverse backgrounds and accelerate the drug discovery process,” said Lawrence Cornett, Ph.D., UAMS vice chancellor for research.

Posters at the showcase, which was held at the UAMS Winthrop P. Rockefeller Cancer Institute, used text and graphics to portray data and  conclusions from months of work by researchers.

Peter A. Crooks, Ph.D., a featured speaker at the event, was eager to promote the benefits of natural products to medical research. “My interests lie in investigating the biological properties of plants,” said Crooks, whose drug discovery research includes work with natural plant products to combat methamphetamine and tobacco addiction.

Crooks was trained in natural products chemistry and serves as professor and chairman of the UAMS Department of Pharmaceutical Sciences in the College of Pharmacy.

Fellow researcher Cesar M. Compadre, Ph.D., shared information on his research that investigates the cancer-fighting properties of a plant native to southern Ecuador. “This particular plant is typically used to fight infection, but we have shown it also has the ability to kill leukemia stem cells,” said Compadre, who has conducted extensive research on bioactive compounds of natural origin. He also is a professor in the UAMS Department of Pharmaceutical Sciences.

Another participant, Michael Borrelli, Ph.D., presented the work of his research team, which includes Crooks and graduate assistant Zheng Chen, on the natural drug parthenolide to inhibit the growth of liver tumor cells. In their research, liver tumors treated with the drug exhibited a significant decrease in volume in only nine days. Borrelli is a professor in the UAMS Department of Radiology in the College of Medicine.

Guests gather to discuss UAMS research projects at the Showcase on Medical Discoveries.
