Abstrakt: Influenza types A and B both cause serious disease in man; vaccines are in use but must be reformulated each year in response to antigenic variation and are frequently ineffective against new influenza variants. Influenza viruses are enveloped RNA viruses which contain two major surface glycoproteins: hemagglutinin (HA) and neuraminidase (NA, EC 3.2.1.18). These proteins are essential for infection and offer potential targets for antiviral drug development. Based upon the knowledge of the most important steps of the whole interaction between virus and host cell, the main purpose of our research was to find a sialic acid analogue for increasing the affinity of the sialic acid cell receptor analogue to the principal binding site of HA. A series of sialic acid analogues were prepared and their structures were designed with the goal to have molecules able to saturate the HA receptor and thereby be potentially useful as anti-influenza drugs.
