Synthesis of conjugates ofL-fucose andortho-carborane as potential agents for boron neutron capture therapy

Abstract

The synthesis of three potential boron neutron capture therapy agents (6–8) is reported. The compounds synthesized are comprised of ortho-carborane covalently attached to L-fucose via C-6. Incorporation of the carborane moiety was achieved either through the reaction of an L-fucose-derived alkyne with decaborane or by the coupling of a 6-amino-L-galactopyranose derivative with carborane carboxylic acid chloride (18).Key words: L-fucose, fucosyltransferase, boron neutron capture therapy, ortho-carborane.
