New Unnatural L-Nucleoside Enantiomers:From Their Stereospecific Synthesis to Their Biological Activities
摘要:
Several purine and pyrimidine beta-L-dideoxynucleosides were stereospecifically synthesized and their antiviral properties examined. Two of them, namely beta-L-2', 3'-dideoxyadenosine (beta-L-ddA) and its 2',3'-didehydro derivative (beta-L-d4A) were found to have significant anti-human immunodeficiency virus (HIV) and anti-hepatitis B virus (HBV) activities in cell culture.
Anti-human immunodeficiency and anti-hepatitis B virus activities of β-l-2′,3′-dideoxy purine nucleosides
摘要:
beta-L-2',3'-Dideoxyadenosine, beta-L-2',3'-didehydro-2',3'-dideoxyadenosine and related compounds were synthesized in a stereoselective manner. These compounds were tested in vitro against HBV in 2.2.15 cell line and against HIV-1 in PBM and CEM cells. It was found that beta-L-2',3'-didehydro-2',3'-dideoxyadenosine (7) exhibited significant anti-HIV (EC(50) 0.38 mu M in PBM cells) and anti-HBV activity (EC(50) 1.2 mu M).
