Copper complexes with potent anti-tumor effect have been extensively developed. Most investigations of their modes of action focused on the biomolecular targets but not the signal transduction between target binding and cell death. We have previously shown that the cytotoxic complex
Phenolic compounds, sodium salicylate and related compounds, as inhibitors of tumor cell growth and inducers of apoptosis in mouse leukemia L1210 cells.

A series of substituted salicylaldehyde dibenzyl semicarbazones [RC6H3(OH)CH=N-NHCON(CH2Ph)2] and their copper(II) complexes were synthesized and characterized. The chloridocopper(II) complexes of the 4-OH and 5-OH substituted ligands (complexes 9 and 7) show modest affinity and good selectivity
Anthracycline toxicity to cardiomyocytes or cancer cells is differently affected by iron chelation with salicylaldehyde isonicotinoyl hydrazone.

OBJECTIVE
The clinical utility of anthracycline antineoplastic drugs is limited by the risk of cardiotoxicity, which has been traditionally attributed to iron-mediated production of reactive oxygen species (ROS).
METHODS
The aims of this study were to examine the strongly lipophilic iron chelator,
Methyl and ethyl ketone analogs of salicylaldehyde isonicotinoyl hydrazone: novel iron chelators with selective antiproliferative action.

Salicylaldehyde isonicotinoyl hydrazone (SIH) is a lipophilic, orally-active tridentate iron chelator providing both effective protection against various types of oxidative stress-induced cellular injury and anticancer action. However, the major limitation of SIH is represented by its labile
