Activity Information


Target Organism  HBV

Assay  Scintillation count

Activity 

  • [Ref.12469306]Hepatitis B virus(HBV): inhibition of the association of L-HBsAg with HBcAg(IC50>1000 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  core antigen (HBcAg)(Viral assembly)

Mechanism  During HBV morphogenesis, both the PreS and S domains of L-HBsAg form docking sites for the viral nucleocapsids. Thus, a compound that disrupts the interaction between the L-HBsAg and nucleocapsids could serve as a therapeutic agent against the virus based upon inhibition of morphogenesis. Peptide inhibits the association of L-HBsAg with core antigen (HBcAg).
