Compound found that targets wide range of viruses

"Now, researchers from the University of Texas Medical Branch at Galveston, UCLA, Harvard University, the U.S. Army Medical Research Institute of Infectious Diseases and Cornell University have teamed up to develop and test a broad-spectrum antiviral compound capable of stopping a wide range of highly dangerous viruses, including Ebola, HIV, hepatitis C virus, West Nile virus, Rift Valley fever virus and yellow fever virus, among others.

"UCLA researchers led by Dr. Benhur Lee — corresponding author on a paper on the work appearing this week on the Proceedings of the National Academy of Science Web site — identified the compound (which they call LJ001), after screening a "library" of about 30,000 molecules to find a one that blocked the host cell entry of deadly Nipah virus. Subsequent experiments revealed that LJ001 blocked other viruses that, like Nipah, were surrounded by fatty capsules known as lipid envelopes. It had no effect on nonenveloped viruses."
