Abstract: The focus of the present invention is an effective anti-poxvirus drug for use in treating or preventing human disease caused by pathogenic poxviruses. More particularly, the present invention relates to antiviral drugs that target the poxvirus proteinase responsible for core protein maturation, a step which is absolutely essential for the production and spread of infectious virions.
