CAY10766 is an antiviral compound.1 It inhibits entry of influenza virus-like particles pseudotyped with hemagglutinin A (HA) from H5N1 influenza A virus into A549 cells (EC50 = 0.24 µM). CAY10766 (1 µM) reduces H1N1 and H5N1 influenza A viral titers in infected MDCK cells. It also exhibits synergy with oseltamivir carboxylate in MDCK cells infected with the influenza A reporter PR8-NS1-Gluc virus.
