Pyridoxal isonicotinoyl hydrazine is a cell-permeable and relatively non-toxic iron (Fe3+) chelator [1].
Pyridoxal isonicotinoyl hydrazone (PIH) is a tridentate Fe-chelating agent that shows high Fe chelation efficacy. In 59Fe-labeled reticulocytes, PIH (0.1 mmol/L) released 38.6% of cellular 59Fe [1]. PIH inhibited the formation of ascorbyl radical and Fe(III)–EDTA-mediated ascorbate oxidation in a dose-dependent way [3].
In Fe-loaded rats, PIH orally administrated resulted in an eightfold increase in fecal Fe excretion and possibly some urinary excretion of Fe [1]. In mice loaded with iron-acetohydroxamic acid complex, pyridoxal isonicotinoyl hydrazone (po.) were given daily for four days at 300 mg/kg/day. Total iron excreted over the 4-day period (micrograms/mouse) was 31 [2]. Pyridoxal isonicotinoyl hydrazine could be used for experimental chelating therapy in iron-overload diseases [3].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
