13 C]KP was prepared by a three-step synthetic scheme from [ 13 C]potassium cyanide in overall yield of 23 %. The racemate was optically resolved by the formation of diastereomeric amides with (R)-(+)-a-phenylethylamine, separation of the amides by column chromatography on silica gel, and nonhydrolytic cleavage of the amide bond using nitrogen tetroxide. The yields of KP enantiomers were 30 % based
对映体 [1- 13 C] 酮洛芬 (KP) 及其酰基葡萄糖醛酸苷的制备已被报道用于对 KP 酰基葡萄糖醛酸苷的立体选择性药代动力学和反应性的核磁共振 (NMR) 光谱研究。外消旋[1- 13 C]KP通过三步合成方案从[ 13 C]氰化钾以23%的总产率制备。通过与(R)-(+)-α-苯基乙胺形成非对映酰胺,通过硅胶柱色谱分离酰胺,以及使用四氧化氮非水解裂解酰胺键,外消旋物被光学拆分。基于外消旋物,KP对映异构体的产率为30%。(R)-和(S)-[1- 13 C]KP的酰基葡萄糖醛酸苷在Sep-Pak C 18预处理后使用制备型高效液相色谱法从人尿中分离每种标记的KP (100 mg)后。给药后 0-4 小时尿液中缀合物的产量约为 50 毫克。
