侧链脂肪酸 BMIPP 的 125I 标记和动物体内分布
125 I radioiodination of BMIPP and its distribution in animals
【摘要】 在乙醇和水的混合溶液中,通过新生态Cu(I)催化碘同位素交换反应制得125I-BMIPP,经乙醚提取纯化后,其放射化学纯度>95%,制备过程中总放射性得率>40%。小白鼠体内分布显示2%左右的注射剂量存在于心肌组织,且长时间保持稳定。
【Abstract】 I-BMIPP was prepared by isotopic exchange using Cu(Ⅰ) as catalyst in an ethanal water mixture. The radiochemical purity of 125 I-BMIPP was >95%, and the overall radioactivity yield was >40%. In rat, the myocardum kept about 2% of injection dose and stabilized in 3 h. It indicated that BMIPP is a suitable agent for myocardial fatty acid metabolism imaging.
