Three new phosphoramidites exhibiting two or three alkyne functions were prepared and introduced at the 5′ end of oligonucleotides. The resulting bis- and tris-alkyne oligonucleotides were conjugated with acetylthiohexyl, ferrocenecarboamide hexyl, or carbohydrate-propyl azides by using click chemistry (CuAAC) to afford polyconjugated oligonucleotides. Conjugations were performed either in solution

We have synthesized a panel of bivalent S-sialoside analogues, with modifications at the 4 position, as inhibitors of influenza virus. These first generation compounds show IC50 values ranging from low micromolar to high nanomolar in enzyme inhibition and plaque reduction assays with two intact viruses, Influenza H1N1 (A/California/07/2009) and H3N2 (A/Hongkong/8/68).
