Synthesis and Biological Activity of 2′-Fluoro-2-halo Derivatives of 9-β-d-Arabinofuranosyladenine

Academic Article


  • The synthesis of 2-halo-9-(2-deoxy-2-fluoro-β-d-arabinofuranoeyl)adenines (4b and 4d) by coupling the 2,6-dihalopurine with 3-acetyl-5-benzoyl-2-deoxy-2-fluoro-d-arabinofuranosyl bromide (2) followed by replacement of the 6-halogen with concomitant removal of the acyl blocking groups is described. 2-Fluoroadenine derivative 4g had to be prepared by the diazotization-fluorination of 2-aminoadenine nucleoside 4e. All three nucleosides provided good increases in life span of mice inoculated with P388 leukemia. The best results were obtained when the compounds were administered q3h×8 on days 1, 5, and 9 after implantation of the leukemia cells. The 2′,3′-dideoxynucleoside 5b, prepared by deacetylation of 4f and deoxygenation of the resultant 4h followed by removal of the benzoyl group of 5a, was slightly active against HIV in cell culture. © 1992, American Chemical Society.
