Activity 

• [Ref.30089693]HIV-1 HXB2:inhibition of cell-cell fusion in TZM-bl cells(IC50=25.3±2.6 nM);
• HIV-1 NL4-3:inhibition of pseudovirus infection in TZM-bl cells(IC50=44.2±2.6 nM);
• HIV-1 JRCSF:inhibition of virus infection in TZM-bl cells(IC50=22.1±3.9 nM).

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

Cytotoxicity 

• No cytotoxicity information or data found in the reference(s) presented in this entry

Binding Target  membrane

Mechanism  The peptide acts by binding to the heptad repeat 1 (HR1) region of gp41 and preventing the interaction of the HR1 and HR2 domains, which is required for virus–cell fusion.(By similar)
