Neuraminidase is a major glycoprotein of influenza virus which is essential for viral infection and offers a potential target for antiviral drug development. Rational drug design of NA inhibitors is now in the clinic and these molecules are effective and safe for the treatment of influenza. Recently, research of structure-based NA inhibitors is becoming an interesting field, leading to a breakthrough in the control of influenza. Here we review the progress in the rational drug design of NA inhibitors in recent years.
Keywords: Influenza virus, neuraminidase, neuraminidase inhibitor, pharmacophore model, antiviral agent
