 AB    A novel 5-o-carboranyl-containing nucleoside,
       5-o-carboranyl-1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracil (6,
       CFAU), was synthesized as a potential intracellular neutron capture
       agent. This compound was prepared in five steps starting from
       5-iodo-1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracil (1). The
       desired carboranyl derivative was obtained by addition of decaborane [as
       the bis(propionitrile) adduct] to the protected acetylenic nucleoside
       precursor followed by debenzoylation. The synthesis of CFAU was also
       performed by glycosylation of the suitably protected
       5-o-carboranyluracil with the appropriate 2-fluoroarabinosyl derivative.
       This compound was evaluated for its cytotoxicity in human lymphocytes,
       monkey cells, and rat and human gliomas cells, as well as for antiviral
       activity against human immunodeficiency virus and herpes simplex virus
       type 1. Its biological activity was compared to
       5-o-carboranyl-1-(2-deoxyribofuranosyl)uracil in these cell culture
       systems, human bone marrow cells, and mice. The results obtained to date
       suggest that CFAU has suitable characteristics as a sensitizer for boron
       neutron capture therapy.
