Fluorinated oligopeptides, especially those having 4,4-difluoro-2-amino butyric acid at the C terminus, may be effective inhibitors of hepatitis C virus NS3 protease. Examples of hexapeptides of the invention, optimized for binding in the S1 specificity pocket of the enzyme, may display IC

s at the sub-micromolar level. Embodiments of tripeptides of the invention, having a keto-acid group at the C-terminus are, likewise, potent inhibitors of NS3 protease.

Des exemples d'hexapeptides selon l'invention, optimisés pour leur liaison dans la poche de spécificité S1 de l'enzyme peuvent présenter IC50s au niveau submicromolaire. Des tripeptides selon l'invention avec groupe ceto-acide au niveau du carbone terminal de chaîne, sont également des inhibiteurs potentiels de la protéase NS3.

N-terminal truncation of the hexapeptide ketoacid 1 gave rise to potent tripeptide inhibitors of the hepatitisCvirus NS3 protease/NS4A cofactor complex. Optimization of these tripeptides led to ketoacid 30 with an IC50 of 0.38 microM. The SAR of these tripeptides is discussed in the light of the recently published crystal structures of a ternary tripetide/NS3/NS4A complexes.
