Rational drug design utilizing available X-ray crystal structures of sialic acid analogues bound to the active site of influenza virus neuraminidase has led to the discovery of a series of potent carbocyclic influenza neuraminidase inhibitors. From this series, GS 4104 (oseltamivir, TAMIFLU) has emerged as a promising antiviral for the treatment and prophylaxis of human influenza infection. This article will summarize the design, discovery, and development of oseltamivir as an oral therapeutic to treat influenza infection.
