Compound found that targets wide range of viruses
Date:2/1/2010

b where much of the cell-culture work was done, as well as mouse studies with Ebola and Rift Valley fever viruses. "We followed up and determined that it was somehow changing the lipid envelope to prevent the fusion of the virus particle with the host cell."

Additional experiments indicated that while LJ001 also interacted with cell membranes, whose composition is nearly identical with that of virus envelopes, it caused them no ill effects. The reason, according to the researchers: Cells can rapidly repair their membranes, but viruses can't fix their envelopes.

"At antiviral concentrations, any damage it does to the cell's membrane can be repaired, while damage done to static viral envelopes, which have no inherent regenerative capacity, is permanent and irreversible," said Lee.
