Activity Information


Target Organism  HIV

Assay  cell-cell fusion inhibition assay

Activity 

  • [Ref.20605950]HIV-1:inhibition of peptide against cell-cell fusion between Jurkat E6-1 and HXBc2 cells(IC50=148±4 nM);inhibition of peptide against virus-cell fusion on CD4-expressing cells(IC50=10±1 nM).

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

Cytotoxicity 

  • No cytotoxicity information or data found in the reference(s) presented in this entry

Binding Target  membrane

Mechanism  N peptide may target an exposed C-helix region of gp41 and can interact with their coiled coil formation within a gp41 dimer,which can inhibit HIV-1 entry.
