Abstract: In order to promote attachment of the ristocetin aglycone molecule to the surface of the influenza virus, the aglycone was derivatized with a hemagglutinin ligand sialic acid moiety using a click reaction. The sialoristocetin derivative exhibited somewhat lower anti-influenza virus activity than ristocetin and aglycoristocetin.

Keywords: ristocetin aglycone – influenza virus – antiviral activity – sialoconjugate
