  • Enterovirus A71 (EV-A71):exerts antiviral activity in HeLa cells(EC50=0.76 ± 0.03 μg/mL);
  • GFP-fused coxsakievirus (H3):exerts antiviral activity in HeLa cells(EC50=0.99 ± 0.09 μg/mL);
  • GFP-fused RSV:exerts antiviral activity in HEp2 cells(EC50=0.99 ± 0.09 μg/mL);
  • GFP-fused VSV:exerts antiviral activity in Vero cells(EC50=1.18 ± 0.09 μg/mL);
  • HIV-1 (NLHX):exerts antiviral activity in Vaginal epithelial cells (VK2)(EC50=2.4 μM);
  • HIV-2 (NLYU2):exerts antiviral activity in Vaginal epithelial cells (VK2)(EC50=3.6 μM).

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

Cytotoxicity 

  • [Ref.15081088]Vero cells:CC50=8.51 μM.

Binding Target  Not found

Mechanism  Melittin suppresses cell fusion mediated by HSV-1 syncytial mutants probably by interfering with the activity of the Na, K ATPase, cellular enzyme involved in the membrane fusion process.
