We compared the influence of three different catechol-O-methyltransferase (COMT) inhibitors (CGP 28014, OR-611 and Ro 40-7592) on the metabolism of no-carrier-added (NCA) 6-[18F]fluoro-L-dopa (6-FDOPA) in one Rhesus monkey. All three COMT inhibitors improved 6-FDOPA availability in plasma, increased the specific uptake in the brain and thus improved 6-FDOPA uptake measurements using positron emission tomography (PET). Best results were obtained with Ro 40-7592.
我们比较了三种不同的儿茶酚-O-甲基转移酶（COMT）抑制剂（CGP 28014、OR-611和Ro 40-7592）对一只恒河猴体内无载体添加（NCA）的6-[18F]氟-L-多巴（6-FDOPA）代谢的影响。所有这三种COMT抑制剂均提高了血浆中6-FDOPA的可用性，增加了大脑中的特异性摄取，从而改善了使用正电子发射断层扫描（PET）进行的6-FDOPA摄取测量。使用Ro 40-7592获得了最佳结果。
