                                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.
