2‐5‐[4‐(3‐[18F]fluoro‐2‐hydroxypropoxy)phenyl]‐2‐oxobenzo[d]oxazol‐3(2H)‐yl}‐N‐methyl‐N‐phenylacetamide ([18F]6) as novel radiotracers for the PET imaging of translocator protein (18 kDa) and showed that (R)‐ and (S)‐[18F]6 had different radioactivity uptake in mouse bone and liver. Thus, (rac)‐, (R)‐, and (S)‐[18F]1 are effective radiolabelling reagents and can be used to develop PET radiotracers by examining
为了将3 [[ 18 F]氟-2-羟丙基部分引入正电子发射断层扫描(PET)放射性示踪剂中,我们进行了(rac)-,(R)-和(S)-[ 18 F]表氟醇( [ 18 F] 1)通过(亲核置换外消旋) - ,(- [R )-或(小号) -缩水甘油基甲苯磺酸酯与18 ˚F -并通过蒸馏纯化。(R)-或(S)-[ 18 F] 1与苯酚前体的开环反应得到对映体富集的[ 18F]氟代烷基化产物,不消旋。然后,我们合成了(rac)‐,(R)‐和(S)‐2‐ 5‐4‐3‐4‐3‐3‐3‐ [ 18 ‐F 18氟‐2‐羟基丙氧基)苯基】‐2‐ oxobenzo [ d ] oxazol‐ 3(2 H)-基} -N-甲基-N-苯基乙酰胺([ 18 F] 6)作为易位蛋白PET(18 kDa)PET成像的新型放射性示踪剂,显示(R)-和(S)-[ 18 F] 6在小鼠骨骼和肝脏中具有不同的放射性吸收。因此,(rac)‐,(R)‐和(S)[
