Activity 

• [Ref.30508603]DENV-1:inhibition of virus infection in Vero cells(58%±2.55% inhibition at 50 μM,IC50=10 μM);
• DENV-2:inhibition of virus infection in Vero cells(IC50=10 μM);
• DENV-3:inhibition of virus infection in Vero cells(60% inhibition at 20μM);
• DENV-4:inhibition of virus infection in Vero cells(55% inhibition at 20μM).

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

Cytotoxicity 

• [Ref.30508603]<20% cytotoxicity against Vero and C6/36 cells at 200 μM.

Binding Target  E protein

Mechanism  The peptide acts as inhibitors by binding to the E protein, suppressing its conformational changes, and preventing its binding to the cellular receptor, thereby inhibiting viral entry.
