Glycogen synthase kinase 3 (GSK-3) is a serine/threonine protein kinase. Development of GSK3 inhibitor Alsterpaullone as a therapeutic agent for mood disorders, such as Alzheimer's disease and bipolar disorder, required the synthesis of a suitably labeled drug product for use in human metabolism and pharmacokinetic studies. Owing to the potential metabolic degradation of the molecule, a multi-labeled
糖原合酶激酶 3 (GSK-3) 是一种丝氨酸/苏氨酸蛋白激酶。开发 GSK3 抑制剂 Alsterpaullone 作为情绪障碍(如阿尔茨海默病和双相情感障碍)的治疗剂,需要合成适当标记的药物产品,用于人体代谢和药代动力学研究。由于分子的潜在代谢降解,采用了利用 14C 的多标记方法。[14C]Alsterpaullone 的合成分别通过甲基-[1, 2-14C]-2-溴乙酸酯和 [1, 2-14C]-2-溴乙醇的不同途径完成。标记的版本基于摩尔放射性进行组合,得到放射化学纯度为 99.0% 和比活度为 54.0 mCi/mmol 的最终产品。版权所有 © 2011 John Wiley & Sons, Ltd.
