The pyrones, 3-hydroxy-2-methyl-4-pyrone (maltol) and 3-hydroxy-2-ethyl-4-pyrone (ethyl maltol) chelate iron with a high affinity and selectivity. The resulting 1:3 (metal-ligand) complexes, being neutral, are able to partition readily across cell membranes and thus may facilitate iron transport across the intestinal...

Zn2+ has been allowed to equilibrate across the red cell membrane using two agents that increase membrane permeability to this ion: the ionophore A23187 and the specific carrier ethylmaltol. Extracellular free Zn2+ was controlled with EGTA (1,2-di(2-aminoethoxy)ethane-NNN'N'tetra-acetic acid] buffers, except...

This paper was designed to investigate the interaction of ethyl maltol with human serum albumin (HSA) under physiological condition by fluorescence, synchronous fluorescence, three-dimensional fluorescence, Fourier transformation infrared spectra, and molecular docking method. Spectroscopic analysis of the emission quenching at...

The pursuit of orally available Fe(III) chelating agents has resulted in several clinical trials of 1,2-dimethyl-3-hydroxypyrid-4-one (CP20). Chromatography of this and related Fe chelators on silica-based columns has proven difficult due to unwanted interactions with the stationary phase, including with...

Accumulation of radioactive iron (59Fe) into isolated fragments of rat small intestine in the presence of two hydroxypyrones, maltol and ethyl maltol, was compared with that in the presence of another chelator of iron(III), nitrilotriacetic acid (NTA). The characteristics of...
