Fig. 1. NMS-873 inhibits both influenza A and B viruses.
(A) Chemical structure of NMS-873. (B) Cellular cytotoxicity of NMS-873 in MDCK cells. (C) Antiviral activity of NMS-873 against representative influenza A and B viruses. The antiviral activity of NMS-873 was determined in plaque reduction assay. Monolayers of MDCK cells overexpressing ST6Gal I were infected with indicated viruses and incubated with overlays containing a serial of concentrations of NMS-873, 1 μM of amantadine or 0.2 μM of oseltamivir carboxylate.
