Activity Information


Target Organism  WNV

Assay 

Activity 

  • [Ref.31351847]West Nile virus(WNV): inhibition of WNV infection in LLCKM-2 monkey kidney epithelial cells(IC50~10μM, 70.0±3.0% inhibition at 128 μM).

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

Cytotoxicity 

  • [Ref.31351847]No cytotoxicity against LLCMK-2 monkey kidney epithelial cells at 100 mg/ml.

Binding Target  envelope

Mechanism  The peptide may play roles in protein-protein rearrangements or bilayer membrane interactions during the entry and fusion process and thus inhibit infection of DENV or WNV.
