Background:The Ebola VP30 is required for viral transcription and can exist in phosphorylated (inactive) and dephosphorylated (active) forms. Results: VP30 is dephosphorylated by PP1; the small PP1-targeting molecule 1E7-03 inhibits VP30 dephosphorylation and viral transcription, thereby blocking viral replication. Conclusion: PP1 plays an important role in Ebola virus transcription. Significance: Targeting PP1 is a feasible approach for inhibition of Ebola virus.

A general approach to 3-fluoro-, 3-chloro-, and 3-bromoquinolines which relies on organosilane-promoted Friedländer reaction of α-haloketones is described. The scope of the methylene component as well as influence of the organosilane component on the outcome of the reaction is studied. The method can be used under parallel synthesis conditions.
