Source  Synthetic construct(derived from angiotensin-converting enzyme 2)



Activity Information


Target Organism  SARS-CoV

Assay  Pseudovirus infection assay

Activity 

  • [Ref.16510163]SARS-CoV:inhibition of pseudovirus infection in HeLa cells(25% inhibition at 100 µM).

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  spike glycoprotein

Mechanism  Virus entry into cells is mediated through interactions between spike (S) glycoprotein and angiotensin-converting enzyme 2 (ACE2), peptide derived from ACE2 could bind with spike glycoprotein and inhibits virus entry.
