[89 Zr]Oxinate4 is a Positron Emission Tomography (PET) tracer for cell radiolabeling that can enable imaging techniques to help better understand cell trafficking in various diseases. Although several groups have synthetized this compound for use in pre-clinical studies, there is no available data regarding the production of [89 Zr]Oxinate4 for human use. In this report, we describe the detailed production of [89 Zr]Oxinate4 under USP <823> and autologous leukocyte radiolabeling under USP <797>. The final product presented high radiochemical purity and stability at 24 h post synthesis (>99%) and passed in all quality control assays required for clinical use. [89 Zr]Oxinate4 did not compromised the white blood cells viability and did not show considerable cellular efflux up to 3 h post labeling. The translation of this technique into human use can provide insight into several disease mechanisms since [89 Zr]Oxinate4 has the potential to label any cell subset of interest.

[ 89 Zr]Oxinate 4 的生产和人用细胞放射性标记

[89 Zr]Oxinate4 是一种用于细胞放射性标记的正电子发射断层扫描 (PET) 示踪剂,可以使成像技术帮助更好地了解各种疾病中的细胞运输。尽管有几个小组已经合成了这种化合物用于临床前研究,但没有关于生产 [89 Zr]Oxinate4 供人类使用的可用数据。在本报告中,我们描述了 USP <823> 下 [89 Zr]Oxinate4 的详细生产以及 USP <797> 下的自体白细胞放射性标记。最终产品在合成后 24 小时表现出高放射化学纯度和稳定性 (>99%),并通过了临床使用所需的所有质量控制测定。[89 Zr]Oxinate4 没有损害白细胞的活力,并且在标记后 3 小时内没有显示出大量的细胞外流。
