Disclosed herein are pyrido[2,3-d]pyrimidines having the structure wherein R1, and R2 are independently selected from nitro and amino; wherein R3 is selected from alkyl (C1-C10) and cycloalkyl (C3-C8); wherein R4 is selected from hydrogen, benzyl, alkyl (C1-C10), cycloalkyl (C3-C8), arylalkyl (C4-C8), and aryl (C3-C8); wherein R5 and R6 are independently selected from hydrogen, benzyl, alkyl (C1-C10), cycloalkyl (C3-C8), arylalkyl (C4-C14), and aryl (C3-C8); wherein R3 and R4 may form a ring; wherein R5 and R6 may form a ring or a heterocyclic structure; and wherein R5 and R6 are independently unsubstituted or substituted, wherein each substituent is independently selected from halogen, amino, alkyl (C1-C6), haloalkyl (C1-C6), alkoxy(C1-C6), alkylenedioxy, aryl, heteroaryl, and cycloalkyl (C3-C8). Also disclosed are methods for the preparation of compounds of Formula I and various intermediates. These compounds are useful as NAD+-dependent DNA ligase inhibitors.
