We have found that niacin-related compounds, particularly picolinic acid, induced apoptosis in human leukemia cells. In this paper, we investigated whether various picolinic acid-related compounds had apoptosis-inducing activities or not. Particularly, fusaric acid, picolinaldehyde, nicotinaldehyde, 2-aminopyridine, and 3-aminopyridine also induced apoptosis in acid, picolinaldehyde, nicotinaldehyde, 2-aminopyridine, and 3-aminopyridine also induced apoptosis in HL-60 cells. These results suggest that pyridine substituted with various groups and the consequent change of resonance structure may have an important role in the induction of apoptosis.
