METHODS
Antiviral Activity
Antiviral activity was measured using an inducible HBV expression system,
5 AD38 cells.( Ladner, S.K. et al., Antimicrob Agents Chemother 41, 1715-20 (1997)). Initial
experiments tested the activity of 10p&8 HAP (percentage viral assembly at 24 hour). For
active molecules, effective concentrations were determined for suppression of HBV production
by 50% and by 90%; this value is reported in p_M. สารประกอบ toxicity was tested in the parent
cell line, HepG2. This is reported as the concentration required to suppress cell growth by 50%, 10 CC50 (in tiLM) and as the ratio of CC50/EC50, also known as the therapeutic index. As a control
and for comparison, the results for the nucleoside analog 3TC (lamivudine) also described.
