Title:

NOVEL LIGAND DESIGN, SYNTHESIS, AND CHARACTERIZATION FOR BIOLOGICAL IRON REMOVAL ​

Iron is a well-known necessity in sustained human biology and health. Despite its requirement in cellular homeostasis, an overabundance of iron is associated with various health defects, such as Alzheimer's, and certain cancers. Hemochromatosis is a genetic illness where an excess of iron builds up in the iron Labile Pool. As a result, the programmed cell death pathway, Ferroptosis, is excessively upregulated leading to inflammation, tissue damage and ultimately vital organ failure. With these conditions in mind and to better understand the biochemistry of such diseases, the molecule TAME-pyr  ([N,N',N''-tris(2-pyridylmethyl)-1,1,1-tris(aminomethyl)ethane]) was assessed for iron chelation and synthesized. It is based on the well-studied iron chelator TACH-pyr ([N,N',N''-tris(2-pyridylmethyl)-1,3,5-cis,cis-triaminocyclohexane]). TAME-pyr was designed to bind to the labile iron pool, potentially removing iron's availability to the ferroptotic cell death pathway. We conducted 3D computational modelling of this iron-ligand complex to best predict its binding and coordination capabilities.
