for conveniently tritiating the aryl methyl sulfones of compounds identified as potent and selective inhibitors of human Cox-2 and as DP receptor antagonists. A base-catalyzed exchange reaction was conducted with deuterated water and the total deuterium incorporation, ranging from 46 to 99%, was calculated using mass spectrometry. Results from these exchanges were used as guidelines for tritium labeling
提出了一种用于方便地氚化被鉴定为人 Cox-2 的有效和选择性抑制剂和 DP 受体拮抗剂的化合物的芳基甲基砜的方法。用氘水进行碱催化交换反应,并使用质谱法计算出总氘掺入量,范围为 46% 至 99%。这些交换的结果被用作氚标记的指南,给出 28–120 mCi/mmol (1.03–4.43 GBq/mmol) 范围内的特定放射性。版权所有 © 2004 John Wiley & Sons, Ltd.
