  • Radiosynthesis and preliminary biodistribution in mice of 6-deoxy-6-[<sup>131</sup>I]iodo-L-ascorbic acid
    作者:Jintaek Kim、Fumihiko Yamamoto、Satoru Karasawa、Takahiro Mukai、Minoru Maeda
    DOI:10.1002/jlcr.1610
    日期:2009.7
    An ascorbate analog labeled with iodine-131, 6-deoxy- 6-[131I]iodo-L-ascorbic acid was prepared for evaluation as an in vivo tracer of L-ascorbic acid. The no-carrier-added radiosynthesis was conducted by nucleophilic bromine–iodine exchange between the brominated precursor and sodium [131I]iodide in 2-pentanone at 130–140°C. HPLC purification using a reverse-phase column gave 6-deoxy-6-[131I]iodo-L-ascorbic acid in radiochemical yield of 36–60% with high radiochemical purity and satisfactory-specific radioactivity in a total preparation time of 90 min. Biodistribution studies in fibrosarcoma-bearing mice showed a high uptake in the adrenal glands, accompanied by low activity of tumor accumulation, accumulation properties similar to previous results obtained with 14C-labeled ascorbic acid and 6-deoxy-6-[18F]fluoro-L-ascorbic acid, in spite of high level of deiodination.

    制备了一种用-131 标记的抗坏血酸类似物--6-脱氧-6-[131I]-L-抗坏血酸,以作为 L-抗坏血酸的体内示踪剂进行评估。在 130-140°C 的温度下,化前体与 [131I]iodide 在 2-pentanone 中通过亲核交换进行无载体放射性合成。使用反相色谱柱进行高效液相色谱纯化,得到 6-脱氧-6-[131I]-L-抗坏血酸,其放射化学收率为 36-60%,放射化学纯度高,特异性放射性令人满意,总制备时间为 90 分钟。在罹患纤维肉瘤的小鼠体内进行的生物分布研究表明,尽管脱程度较高,但肾上腺对该物质的吸收率较高,肿瘤蓄积活性较低,蓄积特性与之前用 14C 标记的抗坏血酸和 6-脱氧-6-[18F]-L-抗坏血酸得到的结果相似。Copyright © 2009 John Wiley & Sons, Ltd.

  • 6-Deoxy-6-fluoro-l-ascorbic acid: crystal structure and oxidative degradation
    作者:Janusz Madaj、Yoko Nishikawa、V.Prakash Reddy、Peter Rinaldi、Tadao Kurata、Vincent M. Monnier
    DOI:10.1016/s0008-6215(00)00183-x
    日期:2000.11
    Ascorbic acid and its oxidation products have been implicated in non-enzymatic modification of proteins in aging and diseases of oxidative stress. We have studied the feasibility of using 6-deoxy-6-fluoroascorbic acid (6) for identification of ascorbic acid degradation products by F-19 NMR spectroscopy. Crystals of compound 6 from nitromethane belonged to the space group P2(1) with a = 5.547(2), b = 6.769(3), c = 9.302(2) Angstrom, beta = 91.80(3)degrees and Z = 2. Atomic coordinates, bond lengths and angles, hydrogen coordinates, anisotropic and isotropic displacement parameters were similar if not identical with those of native ascorbic acid. Similarly, UV properties and oxidation kinetics by CuCl2 at different pH values were essentially identical with ascorbic acid. Using 750 MHz F-19 NMR spectroscopy, five to six new fluorinated products were detected after overnight oxidation of 6 with Cu2+, suggesting that 6 may be a powerful and sensitive tool for assessment of its catabolism in vivo.
