Peptide Name LCD278B

Sequence QLLIRMI

Sequence Length 7

UniProt ID No entry found

Source Synthetic construct

Activity Information

Target Organism HIV

Assay Disintegration assay

Activity

[Ref.12054767]HIV-1:Inhibition of 3′-end processing catalyzed by integrase(IC50>200 µM);no inhibition of HIV-1 infection up to 100 μM.

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

Cytotoxicity

[Ref.12054767]P4 cells: Cell viability estimated by the MTT assay was decreased by about 5% at peptide concentrations higher than 100 μM.

Binding Target Integrase

Mechanism Binding of both viral DNA and host chromosomal DNA are critical steps in IN-catalyzed reactions. The peptide interacted with the catalytic domain of IN interfering with the binding of the DNA substrate and inhibit the replication of virus.
