Synthesis and biological activity of the diphosphorylphosphonate derivatives of (+)- and (–)-cis-9-(4′-hydroxycyclopent-2′-enyl)guanine
Abstract
The carbovir triphosphate analogue 10 and its enantiomer 11 have been synthesized and tested as inhibitors of HIV-reverse transcriptase; the enantiomer 11, more remotely resembling natural nucleotides in stereochemical terms, is surprisingly the more active compound.
