  • 3-hydroxy-2(1H)-pyridinone chelating agents

    Disclosed is a series of improved metal chelating agents, which are highly effective upon both injection and oral administration; several of the most effective are of low toxicity. These chelating agents incorporate within their structure 1-hydroxy-2-pyridinone (1,2-HOPO) and 3-hydroxy-2-pyridinone (3,2-HOPO) moieties with a substituted carbamoyl group ortho to the hydroxy or oxo groups of the hydroxypyridinone ring. The electron-withdrawing carbamoyl group increases the acidity of the hydroxypyridinones. In the metal complexes of said chelating agents, the amide protons form very strong hydrogen bonds with its adjacent HOPO oxygen donor, making these complexes very stable at physiological conditions. The terminal N-substituents provides a certain degree of lipophilicity to said 3,2-HOPO, increasing oral activity. Also disclosed is a method of making the chelating agents and a method of producing a known compound, 3-hydroxy-1-alkyl-2(1H)pyridinone, used as a precursor to the chelating agent, safely and in large quantities.
    揭示了一系列改进的螯合剂,这些螯合剂在注射和口服给药时均非常有效;其中一些最有效的螯合剂毒性较低。这些螯合剂的结构中包含了1-羟基-2-吡啶酮(1,2-HOPO)和3-羟基-2-吡啶酮(3,2-HOPO)基团,其取代的甲酰基团位于羟基吡啶酮环的羟基或氧基的邻位。电子吸引的甲酰基团增加了羟基吡啶酮的酸度。在这些螯合剂属络合物中,酰胺质子与其相邻的HOPO氧供体形成非常强的氢键,使这些络合物在生理条件下非常稳定。末端的N取代基为3,2-HOPO提供了一定程度的亲脂性,增加了口服活性。此外,还公开了一种制备这些螯合剂的方法以及一种生产已知化合物3-羟基-1-烷基-2(1H)吡啶酮的方法,该化合物用作螯合剂的前体,可以安全地大量生产。

  • Hexadentate Terephthalamide(bis-hydroxypyridinone) Ligands for Uranyl Chelation: Structural and Thermodynamic Consequences of Ligand Variation
    作者:Géza Szigethy、Kenneth N. Raymond
    DOI:10.1021/ja201511u
    日期:2011.5.25
    Several linear, hexa- and tetradentate ligands incorporating a combination of 2,3-dihydroxy-terephthalamide (TAM) and hydroxypyridinone-amide (HOPO) moieties have been developed as uranyl chelating agents. Crystallographic analysis of several UO2[TAM(HOPO)(2)]}(2-) complexes revealed a variable and crowded coordination geometry about the uranyl center. The TAM moiety dominates the bonding in hexadenate complexes, with linker rigidity dictating the equality of equatorial U-O bonding. Hexadentate TAM-(HOPO)(2) ligands demonstrated slow binding kinetics with uranyl affinities on average 6 orders of magnitude greater than those of similarly linked bis-HOPO ligands. Study of tetradentate TAM(HOPO) ligands revealed that the high uranyl affinity stems primarily from the presence of the TAM moiety and only marginally from increased ligand denticity. Uranyl affinities of TAM(HOPO)(2) ligands were within experimental error, with TAM-(o-phen-1,2-HOPO)(2) exhibiting the most consistent uranyl affinity at variable pH.
