Source  Synthetic construct



Activity Information


Target Organism  RSV

Assay  Antiviral assay

Activity 

  • [Ref.32124885]Respiratory syncytial virus (RSV):inhibition of viral infection in the MA-104 cell(IC50=0.04mg/ml).

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

Cytotoxicity 

  • [Ref.32124885]MA-104 cells:CC50= 0.04 ± 0.01 mg/ml.

Binding Target  Not found

Mechanism  It is likely that these peptides exert anti-RSV activity through a combination of two mechanisms: destabilization of the viral envelope and competitive inhibition of attachment/fusion of the virus with the target cell.
