Pyridoxal isonicotinoyl hydrazone
Based on 4 publication(s) in Google Scholar
Pyridoxal isonicotinoyl hydrazone is an orally active and lipophilic iron-specific chelator that acts as a non-competitive inhibitor of ferrochelatase (FECH) by binding iron ions. Pyridoxal isonicotinoyl hydrazone disrupts heme biosynthesis, leading to reduced FECH stability and increased protoporphyrin IX (PPIX) accumulation. Pyridoxal isonicotinoyl hydrazone is promising for research of iron-overload diseases (e.g., β-thalassemia).

Biological Activity
Pyridoxal isonicotinoyl hydrazone (50-800 µM; 24-72 h) decreases FECH protein levels without affecting FECH mRNA, accompanied by increased ALAS1 protein at high doses in primary human hepatocytes (PHHs) and HepG2/C3A cells[3].
Pyridoxal isonicotinoyl hydrazone (50 µM; 24 h) reduces FECH protein by 40%, an effect reversed by iron supplementation in HepG2/C3A cells[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.47 mg/mL (5.13 mM); Clear solution
