  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.

  3-羟基吡啶-4-一六齿配体作为潜在抗菌剂的合成，与铁（III）的结合亲和力和体外评估

  摘要：

  铁是细菌生存的关键元素。我们已经设计和合成了两个对铁（III）具有高亲和力的新型3-羟基吡啶-4-一六齿配体，这些配体破坏了细菌对铁的吸收。生物学研究表明，这两种螯合剂对革兰氏阳性和革兰氏阴性细菌均具有显着的抑制作用，因此具有作为抗菌剂的潜力。

  Novel 3-hydroxypyridin-4-one containing tridentate ligands were synthesised and their physicochemical properties characterised, including ionisation constants and stoichiometric titration with Fe(III). There is an urgent demand for orally active iron chelators with potential for the treatment of thalassaemia. In principle, tridentate ligands are likely to be more kinetically stable than bidentate molecules, but to date no satisfactory molecules have been identified. Fe(III) stability constants were assessed by competition with the hexadentate ligand EDTA. In all cases no evidence was found for a tridentate mode of iron chelation; instead the ligands behaved as bidentate hydroxypyridinones. As a consequence they provide no advantage over the more simple alkyl hydroxypyridinones.

  标题：摘要 新型含三齿配体的3-羟基吡啶-4-酮被合成，并对其物理化学性质进行了表征，包括电离常数和与Fe(III)的化学计量滴定。目前急需口服活性铁螯合剂，以潜在治疗地中海贫血。原则上，三齿配体可能比双齿分子更具动力学稳定性，但迄今尚未找到令人满意的分子。通过与六齿配体EDTA竞争评估了Fe(III)的稳定常数。在所有情况下，均未发现三齿铁螯合模式的证据；相反，配体表现为双齿羟基吡啶酮。因此，它们与更简单的烷基羟基吡啶酮相比并无优势。
