  Design, Synthesis, Physicochemical Properties, and Evaluation of Novel Iron Chelators with Fluorescent Sensors

  摘要：

  The synthesis of a range of novel 3-hydroxypyridin-4-ones and 3-hydroxypyran-4-ones linked with different coumarin substituents is described. These compounds have been developed in order to provide a series of molecular probes for the quantification of intracellular labile iron pools. An evaluation of the effect of iron(III) on fluorescence intensity was undertaken. Chelation of iron(III) causes quenching of fluorescence. The relationship between iron(III) concentration and the extent of fluorescence quenching indicates that the metal is chelated in a complex with a metal-to-ligand stoichiometry of 1:3. The fluorescence of hydroxypyridinone compounds was found to be more efficiently quenched by iron(III) than were the hydroxypyranones. The metal-to-ligand stoichiometry at which maximum quenching is observed was found to depend on the site at which coumarin is attached. The efficiency of fluorescence quenching by iron(III) is markedly influenced by solvent polarity and pH. The permeability of two representative fluorescent chelators across human erythrocyte ghost membranes was investigated. The rate of permeability for a series of probes was found to be related to the corresponding ClogP values.

  A series of (3-hydroxypyridin-4-one)-coumarin hybrids were developed and investigated as potential multi targeting candidates for the treatment of Alzheimer's disease (AD) through the incorporation of iron-chelating and monoamine oxidase B (MAO-B) inhibition. This combination endowed the hybrids with good capacity to inhibit MAO-B as well as excellent iron-chelating effects. The pFe(3+) values of the compounds were ranging from 16.91 to 20.16, comparable to more potent than the reference drug deferiprone (DFP). Among them, compound 18d exhibited the most promising activity against MAO-B, with an IC50 value of 87.9 nM. Moreover, compound 18d exerted favorable antioxidant activity, significantly reversed the amyloid-beta(1-42) (A beta(1-42)) induced PC12 cell damage. More importantly, 18d remarkably ameliorated the cognitive dysfunction in a scopolamine-induced mice AD model. In brief, a series of hybrids with potential anti-AD effect were successfully obtained, indicating that the design of iron chelators with MAO-B inhibitory and antioxidant activities is an attractive strategy against AD progression.
