Entecavir is an oral antiviral drug used in the treatment of hepatitis B (HBV) infection. It is marketed under the trade name Baraclude (BMS). Entecavir is a potent deoxyguanosine nucleoside analog with antiviral activity selective for hepadnaviruses. In vitro, the active intracellular form of entecavir, entecavir triphosphate, demonstrates a higher binding affinity for HBV DNA polymerase than the natural guanosine triphosphate substrate and effectively inhibits HBV DNA replication at 3 stages in the replication pathway: priming, reverse transcription and DNA-dependent DNA synthesis. Can be also used as a reference compound.
