Source  Synthetic construct(derived from BmKn2)



Activity Information


Target Organism  HIV

Assay  Luciferase Assay

Activity 

  • [Ref.22536342]human Immunodeficiency viruses-1(HIV-1): inhibition of viral particle(EC50= 2.76 μg/ml (1.65 μM)).

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

Cytotoxicity 

  • [Ref.22536342]TZM-bl cells: CC50 = 38.46 µg/ml.

Binding Target  Not found

Mechanism  Kn2-7 aggregates and inserts into viral envelope so that the hydrophobic peptide region aligns with the lipid core region and the hydrophilic peptide regions form the interior region of the pore, with the help of positive charge of peptide somehow
