Entecavir functions as a guanosine analogue, selectively inhibiting HBV reverse transcriptase, which halts viral DNA synthesis within infected hepatocytes. It has high antiviral potency and a high genetic barrier to resistance, making it a key compound in hepatitis B research.
Research Applications
Viral load reduction in chronic HBV infection
Antiviral resistance mutation analysis
Pharmacokinetic and intracellular uptake profiling
Combination therapy studies with tenofovir or lamivudine
In vitro in hepatocyte cultures and in vivo animal model investigations
