    several protein crystal structures, where V10 was incorporated “accidentally” resulting from the presence of Na3VO4 as a phosphatase inhibitor. In this work we broaden the potential biological applications of V10 by presenting the synthesis and characterization of two decavanadate species where the anion acts as a ligand: (2-hepH)(NH4)[Cu(H2O)2(2-hep)}2V10O28]·4H2O (V10Cu) and (2-hepH)2[Co(H2O)5}2V10O28]·4H2O
    酸盐阴离子H x V 10 O 28 (6- x)-(V 10)是研究最多的属氧酸盐物种之一。在最近的几十年中,几项研究指出其生物学相关性主要来自其与蛋白质(例如肌动蛋白,肌球蛋白或离子泵)结合的能力。另一方面,在几个蛋白质晶体结构中观察到了非功能性结合,其中由于存在作为磷酸抑制剂的Na 3 VO 4而“偶然”掺入了V 10。在这项工作中,我们拓宽了V 10的潜在生物学应用通过介绍阴离子作为配体的两种十酸盐物种的合成和表征:(2- hep H)(NH 4)[Cu(H 2 O)2(2- hep)} 2 V 10 O 28 ]· 4H 2 O(V 10 Cu)和(2- hep H)2 [Co(H 2 O)5 } 2 V 10 O 28 ]·4H 2 O(V 10 Co)(2- hep= 2-羟乙基吡啶)。与游离十酸盐不同,络合物阴离子在模型缓冲溶液(0.1 M 2-(N-吗啉代)乙磺酸,0

    The speciation in the aqueous H+/H2VO4−/H2O2/maltol (Ma), H+/H2VO4−/uridine (Ur) and H+/H2VO4−/H2O2/Ur systems was determined in the physiological medium of 0.150 M Na(Cl) at 25 °C. A combination of quantitative 51V NMR (Bruker AMX500) and potentiometric data (glass electrode) was collected and treated simultaneously by the computer program LAKE. In the quaternary maltol system, the two species VXMa2− and VX2Ma2− (where X denotes the peroxo ligand) were found in the pH region 5–10, in addition to all binary and ternary complexes. Their formation was fast. In the ternary uridine (H+/H2VO4−/Ur) subsystem, altogether three vanadate-uridine (V–Ur) species were found in the pH region 4–10, with compositions VUr2−, V2Ur22− and V2Ur23−. Equilibrium was fast except in weakly acidic solutions when slowly decomposing decavanadates formed. In the quaternary H+/H2VO4−/H2O2/Ur system, five additional species were found at pH > 7. They were of VXUr and VX2Ur compositions. Their formation was fast. Formation constants, compositions and 51V NMR chemical shifts are given for all the species found in the systems, and equilibrium conditions are illustrated in distribution diagrams as well as the fit of the model to the experimental data. Biological and medical relevance of the species (in the treatment of diabetes) are also discussed, with pseudo-physiological conditions modelled.

  • 13C N.M.R. Spectroscopic Studies on the Reactions of Vanadium(V) With 13C2-Labeled Oxalate in Aqueous and 50% v/v Aqueous Acetic Acid Solutions
    作者:RP Farrell、PA Lay

    13 C n.m.r, spectroscopy has been used to study the reactions of vanadate , H2VO4-, with 13C2-labelled oxalate in aqueous and 50% v/v aqueous acetic acid media. The results of the aqueous system corroborate the natural abundance oxalate 13C n.m.r. studies of Ehde and coworkers ( Ehde, P.M., Petterson , L., and Glaser, J., Acta Chem. Scand., 1991, 45, 998) who report the formation of both mono( oxalato )-, [VO2(ox)(OH2)] - , and bis(oxalato)-vanadium(V), cis-[VO2(ox)2]3-, complexes in solution. At 270 K, pH 3.3, and an n.m.r. operating frequency of 100.16 MHz, the former complex appears as a singlet (167.3 ppm ), while the latter resolves into an AB coupling pattern (169.6, 168.8, 166.6, 165.8 ppm ; Jc -c 85 Hz) owing to the inequivalence of carbons trans and cis to the oxo ligands . In 50% v/v aqueous acetic acid both the mono( oxalato ) singlet (166.8 ppm ) and the bis ( oxalato ) AB coupling pattern (169.2, 168.5, 166.2, 165.5 ppm ; Jc -c ≈ 75 Hz) are present but are somewhat broadened and shifted downfield, which is indicative of other species being present. There is also some resolution of new peaks within the broadened signals. These are believed to be due to the presence of the additional complexes, mainly [VO2(ox)( OAc )]2- and cis-[VO2(ox)( OAc )2]3-, generated in the acetic acid medium. At 298 K, the bis(oxalato) complex exhibits a single 13C peak for the inequivalent carbons at 167.6 ppm because of fluxional behaviour. The mono( oxalato ) complex is in rapid equilibrium with free oxalate, giving a second peak at lower value of 165.7 ppm that is pH-dependent. The mechanisms of the fluxionality of the different complexes are discussed.

    13 C n.m.r.光谱被用来研究酸盐 H2VO4- 与 13C2 标记的草酸盐在介质和 50% v/v 醋酸介质中的反应。溶液体系的结果证实了 Ehde 和同事(Ehde, P.M., Petterson , L., and Glaser, J., Acta Chem.Scand.,1991,45,998)报告了溶液中单(草酸)-[VO2(ox)(OH2)]- 和双(草酸)-(V)- 顺式-[VO2(ox)2]3- 复合物的形成。在 270 K、pH 值为 3.3 和 n.m.r. 工作频率为 100.16 MHz 的条件下,前一种络合物显示为单稳态(167.3 ppm),而后一种络合物由于氧配体的反式碳原子和顺式碳原子不相等而解析为 AB 耦合模式(169.6、168.8、166.6、165.8 ppm;Jc -c 85 Hz)。在 50% v/v 的乙酸溶液中,单(草酸)单胞菌(166.8 ppm)和双(草酸)AB 偶联模式(169.2、168.5、166.2、165.5 ppm;Jc -c ≈ 75 Hz)都存在,但都有一定程度的拓宽和下移,这表明还存在其他物种。在拓宽的信号中还可以分辨出一些新的峰值。据信,这是因为在醋酸介质中产生了额外的配合物,主要是 [VO2(ox)( OAc )]2- 和顺式 [VO2(ox)( OAc )2]3- 。在 298 K 时,双(草酸)络合物由于具有通量行为,在 167.6 ppm 处的不等价碳显示出单个 13C 峰。单(草酸)络合物与游离草酸盐处于快速平衡状态,在 165.7 ppm 的较低值处出现第二个峰值,该峰值与 pH 值有关。本文讨论了不同络合物的通性机制。
