The genetically modified nairoviruses of this invention possesses a viral ovarian tumor protease with decreased ability to remove ubiquitin (Ub) and ISG15 tags that the human organism uses to label proteins for removal. Exemplary are Crimean-Congo hemorrhagic fever virus and Erve virus. Unlike complete knockout strains, the modified virus retains enough activity for replication in a human cell line. This creates an immunogenic and non-pathogenic virus that can be used as an effective live vaccine agent for prophylaxis and treatment.

This invention provides a family of compounds that inhibit Class II fructose 1,6-bisphosphate aldolase (FBA), which is implicated in the pathogenic activity of a broad range of bacterial and parasitic agents. The compounds were identified by empirical testing, and provide a basis for further derivatization and optimization of 8-hydroxyquinoline-2-carboxylic acid and related compounds. Crystal structure shows that the compounds don't bind directly to the catalytic site of the enzyme, and so are not defined simply as substrate analogs. Instead, they create a pocket by induced fit, resulting a powerful and specific inhibitory effect on FBA activity.
