Bersacapavir is an HBV capsid assembly modulator that exerts a dual mechanism of action against both early and late stages of HBV infection. It forms complete genome-free empty capsids and inhibits de novo synthesis of cccDNA, making it useful in hepatitis B research.

  • Enhances the rate and extent of HBV capsid assembly.
  • Potently inhibits HBV replication in HepG2.117 and HepG2.2.15 cells.
  • Exhibits additive to synergistic antiviral activity when combined with TDF or ETV.
  • Reduces extracellular HBV DNA, intracellular HBV RNA, extracellular HBe/cAg, and extracellular HBsAg.
  • Inhibits cccDNA formation when added to HBV-infected PHHs.
  • Disrupts pre-formed mature HBV capsids.
  • Can be dissolved in 10% DMSO and 90% corn oil for in vivo dissolution.
