The design and synthesis of potent, tripeptidic acylsulfonamide inhibitors of HCV NS3 protease that contain a difluoromethyl cyclopropyl amino acid at P1 are described. A cocrystal structure of 18 with a NS3/4A protease complex suggests the presence of a H-bond between the polarized C–H of the CHF2 moiety and the backbone carbonyl of Leu135 of the enzyme. Structure–activity relationship studies indicate
