The synthesis of beta-D-Fd(4)C was achieved in a stereoselective fashion fi
om D-xylose. The antiviral activity and cytotoxicity of beta-D-Fd(4)C was
compared with that of beta-L-Fd(4)C and 3TC (Lamivudine). Of the three agen
ts compared, beta-L-Fd(4)C was found to be the most potent antiviral agent.
