Activity 

• [Ref.35216177]HSV-1:inhibition of HSV-1 replication in Vero cells(IC50=3.13 μM,IC90=4.96 μM);
• SARS-CoV-2:inhibition of replication in Vero cells(IC50=0.77 μM μM,IC90=6.96 μM);
• Measles virus(MeV):inhibition of MeV replication in VERO/hSLAM cells(IC50=39.4 μM μM,IC90>50.00 μM);
• influenza virus(H1N1,VR-1894):inhibition of replication in MDKC cells(IC50=4.77 μM,IC90=7.11 μM).

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

Cytotoxicity 

• [Ref.35216177]Vero cells:CC50>100.00 μM

Binding Target  membrane

Mechanism  TL peptides may be able to selectively induce pore formation in highly curved membrane structures (below ~250 nm in diameter), resulting in membrane lysis once a critical number of pores is formed, with the consequence of viral infectivity reduction.
