Chromanone derivatives are highly active antiviral agents. Combinations of chromanones and/or chromanols with HBV polymerase inhibitors, HBV DNA inhibitors or HBV core protein inhibitors and/or isoxazoles and, where appropriate, interferon inhibit the replication of HBV viruses better than agents disclosed previously.
Isoxazoles are highly effective anti-viral agents. Combinations of isoxazoles, dihydropyrimidines and/or lamivudine and, optionally, interferon inhibit the proliferation of HBV viruses better than conventional agents.
