A non-natural nucleoside with combined therapeutic and diagnostic activities against leukemia.

ABSTRACT: Acute lymphoblastic leukemia (ALL) is the most common type of childhood cancer, presenting with approximately 5,000 new cases each year in the United States. An interesting enzyme implicated in this disease is terminal deoxynucleotidyl transferase (TdT), a specialized DNA polymerase involved in V(D)J recombination. TdT is an excellent biomarker for ALL as it is overexpressed in ~90% of ALL patients, and these higher levels correlate with a poor prognosis. These collective features make TdT an attractive target to design new selective anti-cancer agents against ALL. In this report, we evaluate the anti-leukemia activities of two non-natural nucleotides designated 5-nitroindolyl-2'-deoxynucleoside triphosphate (5-NITP) and 3-ethynyl-5-nitroindolyl-2'-deoxynucleoside triphosphate (3-Eth-5-NIT
