ABSTRACTUsing the water eliminated mechanism, reactions of 4-pyridinecarboxylic acid hydrazide and salicylaldehyde, benzaldehyde, cinnamaldehyde, and formaldehyde afforded the corresponding N4[(E)-1-(2-hydroxyphenyl) methylidene] (NHPM), N4-[(E)-2-phenylethylidene] (NPI), N4[(E,2E)-3-phenyl-2-propenylidene] (NPPI), and N4[(E) ethylidene] (NEI) isonicotinohydrazide, in high yields, after several minutes, as reported. These new compounds have shown antitumor activity against two kinds of cancer cells, which are K562 (human chronic myeloid leukemia) and Jurkat (human T lymphocyte carcinoma).
