We are developing inhibitors of the RNA-dependent RNA polymerase of norovirus. Similar to the hepatitis C virus polymerases, this enzyme is essential to viral replication and is highly conserved between all noroviral geno-groups. Therefore, an inhibitor of this enzyme might be an effective treatment or short-term prophylactic agent when administered during a cruise or hospital/nursing home stay, for example. We are currently developing polymerase inhibitors, NNIs using X-ray quality norovirus polymerase crystals.
