Source  Synthetic construct(derived from HIV-1 viral protein R (Vpr))



Activity Information


Target Organism  HIV

Assay  Dot-blot binding assay

Activity 

  • [Ref.17490682]HIV-1:inhibit the activity of RNA-dependent DNA polymerase(IC50>>200 µM);inhibit the activity of DNA-dependent DNA polymerase(IC50>>200 µM);inhibit the activity of Rnase H(IC50>>200 µM);
  • Inhibition of 3′-end processing catalyzed by integrase(IC50>>200 µM);inhibition of strand transfer catalyzed by integrase(IC50>>200 µM);inhibition of disintegration catalyzed by integrase(IC50>>200 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,Reverse Transcriptase

Mechanism  The viral enzymes RT and IN have cardinal roles in the early stages of the replication of retroviruses and retrotransposons. The peptide derived from viral protein R (Vpr) could inhibit integrase(IN) and Reverse Transcriptase(RT) and thus inhibit the replication of HIV-1.
