Benzoic acid inhibitors of influenza virus neuraminidase.

A strategy was developed to design non-carbohydrate inhibitors of influenza virus neuraminidase. Using an iterative cycle of modeling, synthesis, biological testing and X-ray crystallography structure determination, a series of inhibitors based on benzoic acid were produced. The refined structures of three compounds complexed with neuraminidase are reported. The results demonstrate the success of this structure-based drug-design strategy.
