Peptide Name   SA-35

Sequence  MITHGCYTRTRHKHKLKKTL

Sequence Length  20

UniProt ID  No entry found

Source  Synthetic construct



Activity Information


Target Organism  RSV

Assay  Antiviral assay

Activity 

  • [Ref.32124885]Respiratory syncytial virus (RSV):SA-35 caused a significant decrease of the RSV infectivity by 33 times at concentrations 1 mg/ml.

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

Cytotoxicity 

  • [Ref.32124885]MA-104 cells:CC50= 2.1 ± 0.1 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.
