Abstract
The emergence of drug-resistant strains of influenza virus makes exploring new classes of inhibitors that target universally conserved viral targets a highly important goal. The influenza A viral genome is made up of eight single-stranded RNA-negative segments. The RNA promoter, consisting of the conserved sequences at the 3' and 5' end of each RNA genomic segment, is universally conserved among influenza A virus strains and in all segments. Previously, we reported on the identification and NMR structure of DPQ (6,7-dimethoxy-2-(1-piperazinyl)-4-quinazolinamine) (compound 1) in complex with the RNA promoter. Here, we report on additional screening and SAR studies with compound 1, including ex vivo anti-influenza activity assays, resulted in improved cellular activity against influenza A virus in the micromolar range.
