Substituted 2-acylpyridine-alpha-(N)-hetarylhydrazones as inhibitors of ribonucleotide reductase activity and L1210 cell growth.


A series of substituted 2-acylpyridine-alpha-(N)-hetarylhydrazones was prepared and studied for their effects on mammalian ribonucleotide reductase activity using a highly purified enzyme preparation from Ehrlich tumor cells and on mouse leukemia L1210 cell growth in culture. Pyridine-2-aldehyde-2-pyridylhydrazone (PH 22), ethyl-2-pyridylketone-I… (More)
