  Synthesis and evaluation of xanomeline analogs—Probing the wash-resistant phenomenon at the M1 muscarinic acetylcholine receptor

  摘要：

  A series of xanomeline analogs were synthesized and evaluated for binding at the M, muscarinic acetylcholine receptor (M-1 receptor). Specifically, compounds that substitute the O-hexyl chain of xanomeline with polar, ionizable, or conformationally restricted moieties were assessed for their ability to bind to the M, receptor in a wash-resistant manner (persistent binding). From our screen, several novel ligands that persistently bind to the M, receptor with greater affinity than xanomeline were discovered. Results indicate that persistent binding may arise not only from hydrophobic interactions but also from ionic interactions with a secondary M, receptor binding site. Herein, a qualitative model that accounts for both binding scenarios is proposed and applied to understand the structural basis to wash-resistant binding and long-acting effects of xanomeline-based compounds.

  Muscarinic receptors have been implicated in neurological disorders including Alzheimer’s disease, Parkinson’s disease, and schizophrenia. Nineteen derivatives of thiadiazolyltetrahydropyridine (TZTP), a core that has previously shown high affinities towards muscarinic receptor subtypes, were synthesized and evaluated via in vitro binding assays. The title compound, a fluoro-polyethyleneglycol analog of TZTP (4c), was subsequently labelled with fluorine-18. Fluorine-18-labelled 4c was produced, via an automated synthesis, in an average radiochemical yield of 36% (uncorrected for decay), with high radiochemical purity (>99%) and high specific activity (326 GBq/µmol; end-of-bombardment), within 40 min (n = 3). Ex vivo biodistribution studies following tail-vein injection of [¹⁸F]4c in conscious rats displayed sufficient brain uptake (0.4%–0.7% injected dose / gram of wet tissue in all brain regions at 5 min post injection); however, there were substantial polar metabolites present in the brain, thereby precluding future use of [¹⁸F]4c for imaging in the central nervous system.

  毒蕈碱受体与阿尔茨海默病、帕金森病和精神分裂症等神经系统疾病有关。我们合成了噻二唑基四氢吡啶（TZTP）的 19 种衍生物，并通过体外结合试验对其进行了评估。标题化合物是 TZTP 的氟聚乙二醇类似物（4c），随后用氟-18 标记。通过自动合成，在 40 分钟内（n = 3）制备出了氟-18 标记的 4c，平均放射化学收率为 36%（未校正衰变），放射化学纯度高（99%），比活度高（326 GBq/µmol；轰击末）。在有意识的大鼠尾静脉注射[18F]4c后进行的体内外生物分布研究显示，[18F]4c有足够的脑摄取量（注射后5分钟，所有脑区的注射剂量/克湿组织为0.4%-0.7%）；不过，脑内存在大量极性代谢物，因此今后无法将[18F]4c用于中枢神经系统成像。
