  Synthesis of C-4-modified zanamivir analogs as neuraminidase inhibitors and their anti-AIV activities

  摘要：

  With the introduction of bioisosteres of the guanidinium group together with scaffold hopping, 35 zanamivir analogs with C-4-modification were synthesized, and their inhibitory activities against both group-1 and group-2 neuraminidase (H5N1 and H3N2) were determined. Compound 026 exerts the most potency, with IC50 values of 0.58 and 2.72 mu M against N2 and N1, respectively. Further preliminary anti-avian influenza virus (AIV, H5N1) activities against infected MDCK cells were evaluated, and D5 exerts similar to 58% protective against AIV infection, which was comparable to zanamivir (similar to 67%). In a rat pharmacokinetic study, compound D5 showed an increased plasma half-life (t(1/2)) compared to zanamivir following either intravenous or oral administration. This study may represent a new start point for the future development of improved anti-AIV agents. (C) 2012 Elsevier Masson SAS. All rights reserved.

• Efficient Dehydrative Sialylation of C-4-Aminated Sialyl-Hemiketal Donors with Ph₂SO/Tf₂O

  An efficient approach to the dehydrative sialylation of various substrates with C-4-aminated sialyl-hemiketal donors by using the reagent combination of diphenyl sulfoxide and triflic anhydride is reported. By using a C-4-hindered non-nucleophilic amine auxiliary, excellent yields and high alpha-stereoselectivities were obtained for coupling with a wide range of primary and secondary acceptors.
