title: Cytotoxicity and in-vivo tolerance of FdUMP[10]: a novel pro-drug of the TS inhibitory nucleotide FdUMP.
abstract: The cytotoxicity of the 10mer ODN FdUMP[10] towards human colorectal tumor cells was evaluated using a clonogenic assay. FdUMP[10] was more than 100-fold more active than 5-FU at inhibiting colony formation of H630 cells. FdUMP[10] was also evaluated for cytotoxicity in the NCI 60 cell line screen, and showed markedly improved activity relative to 5-FU against numerous tumor cell lines. The in-vivo tolerance of FdUMP[10] is more than three-fold greater per mole fluorinated pyrimidine, than 5-FU.
