Synthesis and biological evaluation of boronated nucleosides for boron neutron capture therapy (BNCT) of cancer

Nucleosides Nucleotides Nucleic Acids. 2001 Apr-Jul;20(4-7):695-8. doi: 10.1081/NCN-100002353.

Abstract

Several N-3 substituted carboranyl Thd analogs were synthesized. These agents as well as some non-boronated nucleosides were evaluated in phosphoryl transfer assays with recombinant human TK1 and TK2. For some carboranyl thymidine analogs, TK1 phosphorylation rates approached 38% that of thymidine. Their in vitro cytotoxicty appeared to correlate with the TK1 levels in the tested cells. In some cases increased uptake in tumor cell nuclei compared with the surrounding cytoplasm was detected in vitro.
