Activity Information


Target Organism  HSV,HIV

Assay  HIV-1 integrase inhibition assay

Activity 

  • [Ref.15081088]Herpes simplex virus type 1 (HSV-1):inhibition of HSV-1 infection in Vero cells(EC50=28.68 μM);
  • Herpes simplex virus type 2 (HSV-2):inhibition of HSV-2 infection in Vero cells(EC50=5.00 μM).
  • [Ref.15482931]HIV-1:Inhibition of 3′-processing catalyzed by integrase(IC50=60 µM);inhibition of strand transfer catalyzed by integrase(IC50=57 µM).

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

Cytotoxicity 

  • [Ref.15081088]Vero cells:CC50>100 μM.

Binding Target  HIV Integrase

Mechanism  The HIV-1 integrase plays a crucial role in the HIV-1 virus replication cycle. The peptide can inhibit the activity of integrase and thus inhibit virus replication.
