RESUMEN

El virus de Hepatitis C (VHC) es el principal agente causante de la Hepatitis tipo no-A no-B a nivel mundial. Actualmente existen 170 millones de personas portadoras del virus en riesgo de desarrollar cirrosis y cáncer hepático. La proteasa NS3 del VHC es esencial para la replicación viral y es por tanto uno de los principales objetivos para el desarrollo de terapias específicas contra la infección ya que además, es codificada por uno de los genes con menor variabilidad dentro del genoma del VHC.
