We have previously reported that the maturation of core protein of hepatitis C virus (HCV) by the cleavage with signal peptide peptidase (SPP) is essential for propagation of HCV. In this study, we examined the inhibitory activity of inhibitors for γ-secretase, another intramembrane cleaving protease, to SPP and revealed that interaction of Val223 in SPP with dibenzoazepine structure in the γ-secretase inhibitors is critical for inhibition of SPP. Treatment with SPP suppressed maturation of HCV core proteins of all genotypes of HCV and did not induce emergence of drug-resistant viruses. These results suggest that SPP is an ideal target for the development of therapeutics against chronic hepatitis C.
