Source  Synthetic construct(derived from HIV-1 integrase)



Activity Information


Target Organism  HIV

Assay  Integrase Assay

Activity 

  • [Ref.16854053]HIV-1:Inhibition of 3′-processing catalyzed by integrase(IC50=113±15 µM);inhibition of strand transfer catalyzed by integrase(IC50=56±7 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  Integrase

Mechanism  HIV-1 integrase (IN) is essential for viral replication. Following reverse transcription of the RNA into DNA by HIV-1 reverse transcriptase, IN integrates the viral DNA into the host genome.The peptide could inbibit integrase(By inhibiting the two steps of IN catalysis: 3′-processing and strand transfer).
