• DUCK HEPATITIS-B VIRUS
• AZIDOTHYMIDINE ANALOGS
• ANTIVIRALS

We have adopted the in vitro hepatocyte culture system of the duck infected with duck hepatitis B virus (HDBV) to an antiviral assay system. Using this method, we found that 2',3'-dideoxy-3'-azidothymidine (N3dT) and 2', 3'-dideoxy-3'-O-methylthymidine (OMeT) had antiviral effects against DHBV replication in the concentrations of 20-50-mu-mol/l and 4-40-mu-mol/l, respectively. The N3dT inhibited the single strand DNA formation (negative strand), which is an intermediate of virus replication. However, the inhibition of single strand DNA synthesis by OMeT was relatively weak. These two compounds may have different mechanisms of DHBV DNA replication inhibition. Two other 3'-substituted pyrimidine analogues tested were very weak inhibitors. Antiviral agents that inhibit the reverse transcriptase activity of the hepadnavirus DNA polymerase could be potential candidates for the chemotherapy of these viruses.
