  Synthesis and biological evaluation of positron emission tomography radiotracers targeting serotonin 4 receptors in brain: [18F]MNI-698 and [18F]MNI-699

  摘要：

  Two new benzodioxane derivatives were synthesized as candidates to image the serotonin 4 receptors by positron emission tomography (PET) and radiolabeled with fluorine-18 via a two-step procedure. Competition binding assays demonstrated that MNI-698 and MNI-699 had sub-nanomolar binding affinities against rat striatal 5-HT4 receptors (Ki of 0.20 and 0.07 nM, respectively). PET imaging in rhesus monkey showed that the regional brain distribution of [F-18] MNI-698 and [F-18] MNI-699 were consistent with the known densities of 5-HT4 in brain. [F-18] MNI-698 and [F-18] MNI-699 are among the first fluorine-18 radiotracers developed for imaging the 5-HT4 receptors in vivo and are currently under preclinical investigation in primates for future human use.

• Rapid Room-Temperature 11C-Methylation of Arylamines with [11C]Methyl Iodide Promoted by Solid Inorganic-Bases in DMF

  substrates with no-carrier-added [11C]methyl iodide in DMF at room temperature to give 11C-methylated products in useful radiochemical yields. In particular, we discovered that some primary arylamines in Li3N-DMF were converted into their formanilides, and that these were readily N-methylated with [11C]methyl iodide, preceding easy basic hydrolysis to the desired [11C]N-methyl secondary arylamines. Use

  11[C] 甲基碘是使用碳 11（t1/2 = 20.4 分钟）标记放射性示踪剂的最广泛使用的试剂，用于正电子发射断层扫描的分子成像。然而，一些用于标记的底物，尤其是伯芳胺和吡咯，对 [11C] 甲基碘反应缓慢。我们发现不溶性无机碱，尤其是 Li3N 或 Li2O，可有效促进此类底物与未添加载体的 [11C] 碘甲烷在室温下在 DMF 中的快速反应，从而得到有用的 11C 甲基化产物。放射化学产率。特别是，我们发现 Li3N-DMF 中的一些伯芳胺转化为它们的甲酰苯胺，并且它们很容易被 [11C] 甲基碘 N-甲基化，然后容易碱性水解成所需的 [11C]N-甲基仲芳胺。固体碱的使用允许在芳氨基上进行选择性反应，并且在某些情况下还避免了不希望的副反应，例如酯基水解。事实证明，超声波装置可用于远程和持续搅拌放射性异质反应混合物，但不会产生“超声波特异性”化学效应。

  The discovery and SAR of potent, selective dioxane-fused tricyclic benz[d]imidazole derivatives as mPGES-1 inhibitor are herein described. Various amide modifications in this series afforded many potent mPGES-1 inhibitors, of which 17d proved to be suitable for further profiling in vivo. Compound 17d (24(2-chloro-6-fluorophenyl)amino)-N-(3-fluoro-5-(trifluoromethyl)pheny1)-1-methy1-7,8-dihydro-1H- [1,4]dioxino[2',3':3,4]benzo[1,2-dlimidazole-5-carboxamide) exhibited excellent mPGES-1 enzyme (IC50: 8 nM), cell (A549 IC50: 16.24 nM) and human whole blood potency (IC50: 249.9 nM). In rodent species, 17d strongly inhibited guinea pig mPGES-1 (IC50: 10.79 nM), but not the rat and mouse enzyme. Furthermore 17d displayed excellent in vitro selectivity over mPGES-2, cPGES, COX-enzymes (COX-1, 2), selectivity against other prostanoid synthases, favorable hERG and CEREP panel profile. Likewise, our lead 17d demonstrated good oral pharmacokinetic profiles and good CNS B/P ratio in rat and guinea pig. Lead 17d also unveiled good efficacy in LPS-induced thermal hyperalgesia pain model with ED50 of 36.7 mg/kg, respectively. (C) 2016 Elsevier Ltd. All rights reserved.
