The synthesis and anti-HIV evaluation of hitherto unknown 3'-fluoro-5'-norcarbocyclic nucleoside phosphonates bearing adenine with modifications at the 4' position (ethynyl, vinyl, ethyl, hydroxymethyl) is described. One of the synthesized compounds was found to be an inhibitor of HIV-1 replication, but with moderate efficiency relative to (R)-9-(2-phosphonylmethoxypropyl)adenine ((R)-PMPA, tenofovir), with no concomitant cytotoxicity.
Keywords: 3′-fluoro-5′-norcarbocyclic nucleosides; anti-HIV; antiviral agents; phosphonates.
