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.
