  Inhibition of human neuraminidase 3 (NEU3) by C9-triazole derivatives of 2,3-didehydro-N-acetyl-neuraminic acid

  摘要：

  We report the synthesis of a series of C9 and N5Ac modified analogs of 2,3-didehydro-N-acetyl-neuraminic acid (DANA) and their inhibitory potency for the human neuraminidase 3 (NEU3) enzyme. We were able to generate a small library of compounds through the synthesis of azide derivatives of DANA, followed by Cu-catalyzed azide-alkyne cycloaddition (CuAAC) to generate triazole-containing inhibitors. Our results suggest that NEU3 can tolerate large hydrophobic groups at the C9 position; however, none of the derivatives made at the N5Ac side-chain were active. We identify three new inhibitors that have comparable potency to the best reported inhibitors of the enzyme. (C) 2010 Elsevier Ltd. All rights reserved.
