NCIt definition : A deoxycytosine analog with potential antineoplastic activity. Upon administration,
DFP-10917 is phosphorylated to generate its nucleotide form that functions as a deoxycytosine
mimic and is incorporated into DNA in tumor cells. This causes DNA strand breaks during
polymerization due to beta-elimination during the fidelity checkpoint, which results
in G2/M phase-arrest and tumor cell apoptosis.;
