A recursive protection scheme for FdUMP is employed by synthesizing ol
igonucleotides consisting of only FdU. 3'-O-exonuclease action release
s FdUMP and a shortened oligonucleotide from which further exonuclease
action releases more FdUMP. Such oligonucleotides are more cytotoxic
to H4IIe, mouse fibroblast, and metastatic mouse tumor cells than are
equivalent concentrations of FdU monomer.
