摘要:
Several L-enantiomers of nucleoside analogues were stereospecifically synthesized by a multi-step reaction from L-xylose and their antiviral properties were examined in vitro. Two of them, namely beta-L-2',3,-dideoxycytidine (beta-L-ddC) and its 5-fluoro derivative (beta-L-FddC) were found to have potent anti-human immunodeficiency virus (HIV) and significant antihepatitis B virus (HBV) activities in cell cultures.
