[h=3]Abstract[/h] Neuraminidase, which plays a critical role in the influenza virus life cycle, is a target for new therapeutic agents. The study of structure-activity relationships revealed that the C-5 position amino group of oseltamivir was pointed to 150-cavity of the neuraminidase in group-1. This cavity is important for selectivity of inhibitors against N1 versus N2 NA. A serial of influenza neuraminidase inhibitors with the oseltavimir scaffold containing lipophilic side chains at the C-5 position have been synthesized and evaluated for their influenza neuraminidase inhibitory activity and selectivity. The results indicated that compound 13o (H5N1 IC[SUB]50[/SUB] = 0.1 ?0.04μM,H3N2 IC[SUB]50[/SUB] = 0.26?0.18 μM) showed better inhibitory activity and selectivity against the group-1 neuraminidase. This study may provide a clue to design of better group-1 neuraminidase inhibitors. This article is protected by copyright. All rights reserved.
