AT-130 inhibits Wt HBV (IC50=2.4 μM), rtL180M HBV (IC50=9.8 μM), rtM204I HBV (IC50=35.6 μM).
AT-130 (0.1, 1, 5, 10, 100 μM; for 7 days) causes dose-dependent inhibition of wt HBV replication in HepG2 cells transduced with HBV baculovirus. AT-130 at a concentration of 2.5 μM, reduces encapsidated HBV DNA by 50% (IC50) and at 18.5 μM by 90% (IC90).
AT-130 has no toxic to either HepG2 or Huh-7 cells at concentrations of up to 250 μM.
AT-130 (0.005, 0.05, 0.5, 5, 50 μM) does not inhibit HBV DNA synthesis by blocking the HBV endogenous DNA polymerase reaction directly in Huh 7 or HepG2 cells. AT-130 inhibits HBV DNA replication in hepatoma cells but has no effect on viral DNA polymerase activity or core protein translation.
AT-130 (2.5, 18.5 μM) has no effect on total HBV RNA production but does reduce encapsidated RNA. AT-130 does not affect core protein or nucleocapsid production and the activity of the protein expression vector.
