abstract：:The binding of the anilido aminoacridine derivative amsacrine with the heme proteins, hemoglobin, and myoglobin, was characterized by various spectroscopic and calorimetric methods. The binding affinity to hemoglobin was (1.21 ± .05) × 105 M-1, while that to myoglobin was three times higher (3.59 ± .15) × 105 M-1. The...
