Abstract

The recent outbreaks of avian flu in Southeast Asia and swine flu in Mexico City painfully exemplify the ability of the influenza virus to rapidly mutate and develop resistance to modern medicines. This review seeks to detail the molecular mechanism by which the influenza virus has obtained resistance to amino-adamantyls, one of only two classes of drugs that combat the flu. Amino-adamantyls target the viral M2 H+ channel and have become largely ineffective due to mutations in the transmembrane domain of the protein. Herein we describe these resistance rendering mutations and the compounded effects they have upon the protein's function and resulting virus viability.
