Discovery and synthesis of novel benzofurazan derivatives as inhibitors of influenza A virus

The identification of a novel hit compound inhibitor of the protein-protein interaction between the influenza RNA-polymerase PA and PB1 subunits has been accomplished by means of high-throughput screening. A small family of structurally related molecules has been synthesized and biologically evaluated with most of the compounds showing micromolar potency of inhibition against viral replication.
