肝受体显像剂99mTc－半乳糖基化人血清白蛋白融合干扰素的制备及其应用
摘要：
肝受体显像剂99mTc－半乳糖基化人血清白蛋白融合干扰素的制备及其应用，属于核药学技术领域。本发明采用亚锡还原法进行半乳糖基化人血清白蛋白融合干扰素GHSA－IFN放射性锝标记，经聚酰胺－66薄层层析分析证实所制备的99mTc－GHSA－IFN放化纯大于90％，室温下可稳定6小时以上，符合科研和临床使用要求。小鼠体内分布和大鼠显像结果表明99mTc－GHSA－IFN可特异性地被肝脏所摄取，10－30分钟时，肝脏显像十分清晰，是肝脏显像的最佳时间。因此，99mTc－GHSA－IFN是一种较好的新型肝受体功能SPECT显像剂，可用于评价肝受体功能，诊断肝脏疾病，评判肝病治疗药物疗效；同时它还用于制备肝靶向治疗药物，可用于制备病毒性肝炎的治疗药物。
摘要（英）：

Disclosed are a preparation method for hepatic receptor imaging agent 99mTc-galactosyl-human serum albumin fusion interferon and the application of the albumin fusion interferon, belonging to the nuclear medicine technical field. The invention adopts a stannous reduction method for the radioactive technetium tagging of the hepatic receptor imaging agent 99mTc-galactosyl-human serum albumin fusion interferon GHSA-IFN; upon polyamide-66 thin layer chromatography analysis, the radiochemical purity of the prepared 99mTc-GHSA-IFN is more than 90% and can be stabilized for more than 6 hours at room temperature, in line with the requirements of scientific research and clinical use. The distribution in mice and the imaging results of rats show that the 99mTc-GHSA-IFN can be incepted by liver in a specific way, and the liver imaging is very clear within 10-30 minutes which is the best time for liver imaging. Therefore, the 99mTc-GHSA-IFN is a good new liver receptor function SPECT imaging agent and can be used to evaluate the liver receptor functions, diagnose liver diseases and evaluate the liver disease treatment drug efficacy; at the same time, the 99mTc-GHSA-IFN is also used to prepare liver targeted therapy drugs and the treatment drugs for viral hepatitis.
