(lipopolysaccharide)-treated rats have confirmed the high potential of MH derivatives for imaging neuroinflammation. Here, we report the synthesis of four structural analogs of honokiol, of which 4′-(2-fluoroethoxy)-2-hydroxy-5-propyl-1, 1′-biphenyl (F-IV) was selected for labeling with fluorine-18 (T1/2 = 109.8 min) due to its high anti-inflammatory activity confirmed by enzyme immunoassays (EIA) and neuromorphological
许多药理学研究证明,新木脂素和厚朴酚和 4'- O-甲基和厚朴酚(MH) 及其衍生物具有显着的抗炎活性。文献数据表明,2 型环氧合酶 (COX-2) 可能是这些化合物在体外和体内的靶标。最近对 [ 11 C]MPbP ( 4'-[ 11 С] 甲氧基-5-丙基-1,1'-联苯-2-醇) 在 LPS(脂多糖)处理的大鼠中的生物分布的研究证实了 MH 衍生物的高潜力用于神经炎症成像。在这里,我们报告了和厚朴的四种结构类似物的合成,其中选择了4'-(2-fluoroethoxy)-2-hydroxy-5-propyl-1, 1'-biphenyl ( F-IV ) 用于标记氟- 18(吨1/2 = 109.8 分钟),因为酶免疫分析 (EIA) 和神经形态学研究证实了其具有高抗炎活性。F-IV对 COX-2的高抑制效力及其中等亲脂性和化学稳定性是在啮齿动物神经炎症模型中初步评估放射性配体[ 18
