Activity 

• [Ref:14694985]HCV:IC50=inhibition of activation of NS3-6K protease(50 nM)(0.1% inhibition at 3 µM).

Hemolytic Activity  No hemolysis information or data found in the reference(s) presented in this entry

Cytotoxicity  No cytotoxicity information found in the reference(s) presented

Binding Target  NS3 protease

Mechanism  HCV NS3 protease is essential for the processing of HCV polyprotein, this protease is a target of choice to control HCV replication. The peptide was demonstrated that can indeed block the activity of NS3 and thus inhibit HCV replication
