In Vitro After phosphorylation to di- and triphosphate forms, LB80317 is incorporated into the viral DNA inside the nucleocapsid, which inhibits further DNA synthesis. In in vitro studies using cell line models, the drug concentrations causing 50% reduction in HBV DNA produced (EC50) is 0.5 μM for LB80317.
In Vivo Forty percent of the amount of LB80331/LB80317 in the mouse liver is detected as the phosphorylated form. LB80380 is rapidly absorbed and converted to LB80331. LB80317 has a long half-life at steady-state (T1/2=8.3-9.9 hours),
Target EC50: 0.5 μM (DNA synthesis of HBV)
