Inhibition of RNA Viruses In Vitro and in Rift Valley Fever-Infected Mice by Didemnins A and B

Didemnins, a new class of depsipeptides isolated from a Caribbean tunicate, have been shown to have potent antiviral activity against a broad range of RNA viruses in vitro. Didemnins A and B both protected mice against a lethal challenge of Rift Valley fever virus.
