Popis: [Image: see text] Treatment of dengue virus (DENV) and other flavivirus infections is an unmet medical need. The highly conserved flaviviral NS5 RNA-dependent RNA polymerase (RdRp) is an attractive antiviral target that interacts with NS3 and viral RNA within the replication complex assembly. Biochemical and cell-based evidence indicate that targeting cavity B may lead to dual RdRp and NS5–NS3 interaction inhibitors. By ligand-based design around 1H-pyrido[2,1-b][1,3]benzothiazol-1-one (PBTZ) 1, we identified new potent and selective DENV inhibitors that exert dual inhibition of NS5 RdRp and NS3–NS5 interaction, likely through binding cavity B. Resistance studies with compound 4 generated sequence variants in the 3′-untranslated region of RNA while further biochemical experiments demonstrated its ability to block also RNA-NS5 interaction, required for correct RNA synthesis in cells. These findings shed light on the potential mechanism of action for this class of compounds, underlying how PBTZs are very promising lead candidates for further evaluation.
