Antiviral research

The highly lethal filoviruses, Ebola and Marburg cause severe hemorrhagic fever in humans and non-human primates. To date there are no licensed vaccines or therapeutics to counter these infections. Identifying novel pathways and host targets that play an essential role during infection will provide potential targets to develop therapeutics. ⋯ Investigation of the mechanism of action of the compound revealed that it had antioxidant properties. Specifically, compound NSC 62914 was found to act as a scavenger of reactive oxygen species, and to up-regulate oxidative stress-induced genes. However, four known antioxidant compounds failed to inhibit filovirus infection, thus suggesting that the mechanistic basis of the antiviral function of the antioxidant NSC 62914 may involve modulation of multiple signaling pathways/targets.
