  Synthesis and anti-influenza evaluation of orally active bicyclic ether derivatives related to zanamivir

  摘要：

  We synthesized bicyclic ether sialidase inhibitors Such as tetrahydro-furan-2-yl. tetrahydro-pyran-2-yL and oxepan-2-yl derivatives related to zanamivir. These compounds substituted by diol at the C-3' and C-4' positions resulted in the retention of low nanomolar inhibitory activities against not only influenza A virus sialidase but also influenza A virus in cell culture. Compound I la in particular showed comparable efficacy in vivo relative to that of oseltamivir phosphate. (C) 2003 Elsevier Science Ltd. All rights reserved.
