In silico and in vitro methods to identify ebola virus VP35-dsRNA inhibitors

[Display omitted] Ebola virus continues to be problematic as sporadic outbreaks in Africa continue to arise, and as terrorist organizations have considered the virus for bioterrorism use. Several proteins within the virus have been targeted for antiviral chemotherapy, including VP35, a dsRNA binding protein that promotes viral replication, protects dsRNA from degradation, and prevents detection of the viral genome by immune complexes. To augment the scope of our antiviral research, we have now employed molecular modeling techniques to enrich the population of compounds for further testing in vitro. In the initial docking of a static VP35 structure with an 80,000 compound library, 40 compounds were selected, of which four compounds inhibited VP35 with IC50
