AB A new acyclic nucleoside phosphonate (13) containing an adenine moiety
was synthesized, which acted as an excellent inhibitor of calf mucosal
adenosine deaminase. This inhibitory property allows it to exert great
synergistic effect on certain antiviral agents (e.g., ara-A, 37).
Phosphonate 13 was not phosphorylated by the bovine brain guanylate
kinase nor by 5-phosphoribosyl 1-pyrophosphate synthetase. Syntheses of
biologically active nucleotide phosphonate 40 and its phosphonoamidate
derivative 42 were accomplished, which showed remarkable activity
against herpes viruses and exhibited low host cell toxicity.
3'-Azido-nucleoside phosphonate 20 and 3'-fluoronucleoside phosphonate
32, as well as the corresponding dinucleotide analogs 47 and 48, and
their respective phosphonoamidates 53-56 were also synthesized as new
compounds, among which phosphonoamidates 53-56 showed potent activity
against human immunodeficiency virus. Phosphonoamidates 55 and 56
bearing a methyl D-alaninate moiety exhibited less cellular toxicity
than 53 and 54 bearing a methyl L-alaninate moiety. Nucleotide
phosphonate 40 as well as dinucleotide phosphonates 47 and 48 were found
susceptible to degradation by phosphodiesterases. Their respective
phosphonoamidates 42 and 53-56, however, were completely resistant to
snake venom and spleen enzymes.
