Sequence SALEEQYKTFLDKFMHELEDLLYQLSL

Sequence Length 27

UniProt ID No entry found

Source Synthetic construct

Activity Information

Target Organism SARS-CoV-2

Assay plaque assay

Activity

[Ref.33580154]SARS-CoV-2:93% inhibition of replication in Vero-E6 cells at 10 μM;inhibition of replication in Calu-3 cells(IC50=53 nM).

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

Cytotoxicity

[Ref.33580154]The peptide proved to be devoid of cell toxicity on Vero-E6 and Calu-3 cells.

Binding Target Not found

Mechanism The peptide was designed mimicking the N-terminal helix of hACE2 protein,which could prevent the SARS-CoV-2 from infecting human cells, blocking the interaction between hACE2 and the virus spike protein.
