Abstract
The dCTP pyrophosphatase 1 (dCTPase) is a nucleotide pool “housekeeping” enzyme responsible for the catabolism of canonical and noncanonical nucleoside triphosphates (dNTPs) and has been associated with cancer progression and cancer cell stemness. We have identified a series of piperazin-1-ylpyridazines as a new class of potent dCTPase inhibitors. Lead compounds increase dCTPase thermal and protease stability, display outstanding selectivity over related enzymes and synergize with a cytidine analogue against leukemic cells. This new class of dCTPase inhibitors lays the first stone toward the development of drug-like probes for the dCTPase enzyme.
