New compounds show promise against hepatitis C infection

Dr. Samuel Wheeler French Jr., MD, PhD, Assistant Professor of Pathology and Laboratory Medicine at UCLA and researcher at UCLA's Jonsson Comprehensive Cancer Center, is a liver pathologist who is currently developing a proteomic-based program to study the development of liver cancer from hepatitis C viral infection. His most recent study results, to be presented in an American Society for Investigative Pathology (ASIP) symposium on "Pathobiology of Liver Injury and Fibrosis" on April 12 at Experimental Biology 2011, evaluate the effects of several flavonoids on hepatitis C viral infection.

Previously, Dr. French has shown that quercetin, a plant-derived bioflavonoid used by some as a nutritional supplement, attenuates Hepatitis C virus production with no cell toxicity. In his most recent research, French and colleagues found that two other bioflavonoids, catechin and naringenin, displayed antiviral activity on tissue culture. The next step is to determine through a Phase I Clinical Trial that they are safe for patients with chronic hepatitis C infection.

"We now have several new compounds we can test to see if they reduce virus infection," said Dr. French. "The positive thing about this family of compounds is that they are nontoxic, and can be taken at high doses. Bioflavonoids represent a very promising therapy with very few side effects that could help millions of people."
