摘要
正电子发射型计算机断层显像(positron emission tomography,PET)是核医学领域重要的诊断及显像工具,在基础医学诊断、新药研发和疗效评价等各方面发挥越来越重要作用。18 F是PET显像最常用的核素,但18 F需要加速器生产。68 Ga为PET显像核素,可以从长寿命的68 Ge/68 Ga发生器装置获得,不必依赖加速器。随着配位化学的发展,各种双功能螯合剂用于68 Ga的标记,可将68 Ga与多种化学结构及生物分子连接并且可以药盒化68 Ga标记药物。本文主要介绍近期68 Ga标记放射性药物的研究进展。
Positron emission tomography(PET)is an important diagnosis and imaging tool for nuclear medicine,and playing an increasing part in fundamental medicine,new drug research and clinical effect assessment,etc.18 F is the most common radionuclide for PET imaging,which is produced in a cyclotron.68 Ga is a PET imaging radionuclide of increasing concern,and is gained from long-lived 68 Ge/68 Ga generator systems.The use of 68 Ga does not demandan on-site cyclotron,which provide a convenient method for researchers.With the development of coordination chemistry,a variety of bifunctional chelators have been developed for 68 Ga labeling,which allow the convenient coupling tomany chemical structures and biomolecules.Kit-formulated preparation is another advantage for 68 Ga radiopharmaceuticals.This review presents the developments of the 68 Ga-based radiopharmaceuticals.
