General Information


DRAVP ID  DRAVPe00961

Peptide Name   P10(derived from HCV polyprotein)

Sequence  ADLEVVAATYVLVA

Sequence Length  14

UniProt ID  P26662 

Source  Synthetic construct(derived from Hepatitis C virus(HCV) polyprotein)



Activity Information


Target Organism  HCV

Assay  NS3-6K inhibition assay(determined by Fluorescent probe)

Activity 

  • [Ref.14694985]Hepatitis C virus(HCV):inhibition of activation of NS3-6K protease(50 nM)( 6±11% inhibition at 1 µM;27±5% inhibition at 3 µM; 75±1% inhibition at 10 µM; IC50=6.3µM).

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
