Synthesis of Novel 4′-Trifluoromethyl-5′-Norcarbocyclic C-Nucleoside Phosphonic Acids as Potent Anti-Leukemic Agents

Abstract

The syntheses of novel C-nucleoside phosphonic acids as potential antiviral agents are described. The sugar moiety that served as the nucleoside skeleton was produced starting from commercially available 1,3-dihydroxy cyclopentane. The key C-C bond formation from sugar to base precursor was performed using the Knoevenagel-type condensation. The synthesized compounds exhibited anti-HIV activity and cytotoxicity. Also, the synthesized compounds were screened in vitro for tumor growth inhibitory activity against mouse leukemia cell lines (L-1210, P-815).
