Activity Information


Target Organism  HIV

Assay  Disintegration assay

Activity 

  • [Ref.12054767]HIV-1:Inhibition of 3′-end processing catalyzed by integrase(IC50>200 µM);no inhibition of HIV-1 infection up to 100 μM.

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

Cytotoxicity 

  • [Ref.12054767]P4 cells: Cell viability estimated by the MTT assay was decreased by about 5% at peptide concentrations higher than 100 μM.

Binding Target  Integrase

Mechanism  Binding of both viral DNA and host chromosomal DNA are critical steps in IN-catalyzed reactions. The peptide interacted with the catalytic domain of IN interfering with the binding of the DNA substrate and inhibit the replication of virus.
