Matrix metalloproteinases (MMPs) are key enzymes involved in cancer invasion and metastasis. New 18F-labeled MMP inhibitors (1a–c) has been designed and synthesized for cancer imaging by positron emmision tomography. The precursors were synthesized in four steps starting from D-form of amino acids. Radiosynthesis of 1a–c were carried out by simple one-pot synthesis. The resulting radiofluorinated MMP inhibitors were obtained in overall radiochemical yields of 13–43% (EOB, decay corrected) within 60–70 min (including final preparative HPLC separation).

基质金属蛋白酶(MMP)是参与癌症侵袭和转移的关键酶。新型 18F 标记的 MMP 抑制剂 (1a–c) 已被设计和合成,用于通过正电子发射断层扫描进行癌症成像。从 D 型氨基酸开始,分四步合成前体。 1a-c 的放射合成通过简单的一锅合成进行。在 60-70 分钟内(包括最终的制备型 HPLC 分离),得到的放射性氟化 MMP 抑制剂的总放射化学产率为 13-43%(EOB,衰减校正)。版权所有 © 2002 约翰威利父子有限公司
