14C-Labeled farnesyl-protein transferase inhibitor 1a was required for drug metabolism studies. The first approach was to synthesize 14C-labeled 1b using Zn(14CN)2 in a Pd-catalyzed cyanation. A second approach was to prepare labeled 1c with the 14C-label in the piperazine ring. All metabolites from 1b were non-radioactive whereas the same metabolites from 1c were all radioactive and quantifiable. Copyright © 2008 John Wiley & Sons, Ltd.
药物代谢研究需要 14C 标记的法尼基蛋白转移酶
抑制剂 1a。第一种方法是在 Pd 催化
氰化反应中使用 Zn(14CN)2 合成 14C 标记的 1b。第二种方法是制备在
哌嗪环上带有 14C 标记的标记 1c。 1b 中的所有代谢物均无放射性,而 1c 中的相同代谢物均具有放射性且可定量。版权所有 © 2008 约翰·威利父子有限公司
