Pyridone structural requirements for activity against murine P-388 leukemia have been extended to isosteric analogs of 3-hydroxy-4-pyridone, a compound previously found to have activity. An amino group can be substituted for the 3-hydroxyl function with retention of activity. A sulfur, but not an amino function, can replace the lactam oxygen in the 2-position. Relocation of the lactam oxygen from the 2- to the 4-position in the pyridine ring also produces active pyridones, including 2-methyl-3…

TLDR
The lack of activity of O-alkylated and monosubstituted analogs suggests that o-quinone formation may be important for activity, a possibility supported by the observed P-388 activity of 5-hydroxydopamine compared with the inactivity of the 6-hydroxy isomer.
