In this report, an automated 11C-N-methyl-α-amino-isobutyric acid production on a Tracerlab FXC Pro module is described. Bioburden to the sterile filter was minimized during solid-phase extraction formulation of the HPLC purified product by the use of sterile aqueous solutions. The optimized solid-phase extraction formulation conditions are fast, give a high recovery of the product, and effectively remove organic solvents and adjust the pH. The final product was obtained within 30–35 min, delivering 1.5–5 GBq in 10 mL sterile phosphate buffer. The product fulfills in every respect our stringent batch release specifications including residual solvents, bioburden, and sterility. The robustness of the automated 11C-N-methyl-α-amino-isobutyric acid production has been demonstrated during more than 40 productions for preclinical use without any failures in regard to product amounts or release specifications.

在本报告中,描述了一种在Tracerlab FXC Pro模块上自动化生产11C-N-甲基-α-氨基异丁酸的方法。在HPLC纯化产品的固相提取制剂过程中,通过使用无菌水溶液,将对无菌过滤器的生物负荷降至最低。优化后的固相提取制剂条件迅速、产品回收率高,并能有效去除有机溶剂和调整pH值。最终产品在30-35分钟内获得,提供1.5-5GBq的10毫升无菌磷酸盐缓冲液。该产品在残留溶剂、生物负荷和无菌性等各方面均符合我们严格的批次释放标准。自动化生产11C-N-甲基-α-氨基异丁酸的稳健性在40多次预临床生产中得到了证明,未出现任何产品数量或释放标准方面的失败。版权 © 2013 John Wiley & Sons, Ltd.
