A series of 2,6-disubstituted aminoalkoxypyrimidine carboxamides (AAPCs) with potent inhibition of bacterial NAD(+)-dependent DNA ligase was discovered through the use of structure-guided design. Two subsites in the NAD(+)-binding pocket were explored to modulate enzyme inhibitory potency: a hydrophobic selectivity region was explored through a series of 2-alkoxy substituents while the sugar (ribose) binding region of NAD(+) was explored via 6-alkoxy substituents.
