    • Disclosed herein is a method of preparing a 188Re-tricarbonyl complex for radiopharmaceutical use and of preparing a precursor thereof, and a contrast agent using the same. Particularly, this invention provides a method of preparing a 188Re-tricarbonyl precursor by reacting perrhenate with borane-ammonia (BH3.NH3), potassium boranocarbonate (K2[H3BCO2]) and phosphate in the presence of borohydride exchange resin as a reducing agent, and a method of preparing a 188Re-tricarbonyl complex by reacting the 188Re-tricarbonyl precursor with a ligand. According to the method of this invention, the borohydride exchange resin is used as a reducing agent and as an anion scavenger, thereby obtaining the 188Re-tricarbonyl precursor and complex having high radiolabeling yield and high purity. In addition, the 188Re-tricarbonyl complex can be used as a contrast agent having excellent plasma stability.
    • 本发明公开了一种制备用于放射性药物使用的188重复三羰基络合物和制备其前体的方法,以及使用其的造影剂。 特别地,本发明提供了一种通过使高铼酸盐与硼烷 - 氨(BH 3 N,NH 3)反应制备188重复三羰基前体的方法, 硼酸氢钾(K 2 H 3 BCO 2))和磷酸盐在硼氢化物交换树脂作为还原剂存在下反应,和 通过使188重复三羰基前体与配体反应制备188重复三羰基络合物的方法。 根据本发明的方法,使用硼氢化物交换树脂作为还原剂和阴离子清除剂,从而获得具有高放射性标记产率和高纯度的重氮三羰基前体和复合物。 另外,重复三羰基复合物可用作具有优异的等离子体稳定性的造影剂。
