2-5A-antisense chimeras: inhibitors of respiratory syncytial virus infection.

A new approach to the chemical control of respiratory syncytial virus infection is reviewed in the context of the biology of the virus and previous treatment approaches. Conjugation of the interferon action mediator, 2',5'-oligoadenylate (2-5A), to antisense agents provides a strategy for the selective ablation of RNA. This application of this technology to respiratory syncytial virus has provided a potent selective inhibitor of virus replication.
