Biological target:

BAY 41-4109 is an inhibitor of human hepatitis B virus (HBV) with an IC50 of 53 nM.

In vitro activity:

HepG2.2.15 cells were used to investigate the antiviral effects of Bay 41-4109 by using real-time polymerase chain reaction (PCR), western blotting, and immunofluorescence. The C terminally truncated core protein was expressed and purified. Changes in hepatitis B capsid formation were assayed by dynamic light scattering and transmission electronic microscopy. Bay 41-4109 was found to be a highly selective and potent inhibitor of hepatitis B virus replication in HepG2.2.15 cells. This compound was equally effective at inhibiting HBV DNA release and the cytoplasmic HBcAg level, with 50% inhibitory concentrations of 32.6 and 132 nM, respectively. HBV DNA and HBcAg were inhibited in a dose-dependent manner, indicating that the anti-HBV mechanisms are associated with and dependent on the rate of HBcAg inhibition. Bay 41-4109 treatment disassembled the core capsids and separated them into monomers or dimers, the form in which they could be further degraded into peptides. The core protein assembled in a misdirected manner cannot function effectively. These results suggest that, based on its particular activities, Bay 41-4109 is a promising anti-HBV candidate.

In vivo activity:

The antiviral effect of Bay 41-4109 was evaluated in a mouse model with humanized liver. Alb-uPA/SCID mice were transplanted with human hepatocytes and infected with HBV (hepatitis B virus). Ten days post-infection, the mice were treated with Bay 41-4109 for five days. During the 30 days of follow-up, the HBV load was evaluated by quantitative PCR. At the end of treatment, decreased HBV viremia of about 1 log(10) copies/ml was observed. By contrast, increased HBV viremia of about 0.5 log(10) copies/ml was measured in the control group. Five days after the end of treatment, a rebound of HBV viremia occurred in the treated group. Furthermore, 15 days after treatment discontinuation, a similar expression of the viral capsid was evidenced in liver biopsies. These findings demonstrate that Bay 41-4109 displayed antiviral properties against HBV in humanized Alb-uPA/SCID mice.
