Several pronucleotide analogs of the model anti-HBV dinucleotide 3'-dA-U(2'OMe) have been synthesized and evaluated for stability, bioreversibility and cytotoxicity. These studies have helped identify potential candidates for further evaluation.
During the past decade, nucleotide analogs have emerged as novel antiviral agents against hepatitis B virus. Adefovir dipivoxil, a prototype phosphonate analog, has been approved for chronic hepatitis B virus therapy, and additional phosphonate analogs and di- and tri-nucleotides are under development. Several innovative prodrug derivatizations have also been reported to improve the oral bioavailability of nucleotide analogs, which usually carry a negative charge.
