制备方法与用途

5--6-皮考啉腈可用作医药合成中间体,适用于实验室研发和化工医药合成过程。

其制备方法如下: 将二甲基甲酰氯(12.9 mL,0.14 mol)的二氯甲烷(23 mL)溶液滴加到搅拌下的3-溴-2-氯吡啶1-氧化物(C27,11.23 g,53.9 mmol)和三甲基甲硅烷化物(17.5 mL,0.14 mol)的二氯甲烷(200 mL)溶液中。将反应混合物在回流下加热3天后,用二氯甲烷(450 mL)稀释,并依次用饱和碳酸氢钠溶液(2 × 200 mL)和(200 mL)洗涤。之后,使用硫酸干燥并真空浓缩。

通过硅胶色谱法纯化(梯度:15% 至 20% 乙酸乙酯庚烷溶液),得到目标化合物二甲基基甲酰基化物(12.73 g,100%),其为灰白色固体。最终产率为7.83 g,36.0 mmol,收率67%。

    M4 PAMs that can be conveniently radiolabeled with carbon-11 as PET tracers for the in vivo imaging of an allosteric binding site of the M4 receptor. We first demonstrated its feasibility by mapping the receptor distribution in mouse brain and confirming that a lead molecule 1 binds selectively to the receptor only in the presence of the orthosteric agonist carbachol. Through a competitive binding affinity
    使用正电子发射断层扫描(PET)来测量受体占有率(RO)在指导中枢神经系统定向疗法的发现和开发中发挥了重要作用。我们和其他人已经研究了毒蕈碱型乙酰胆碱受体4(M4)阳性变构调节剂(PAM),用于治疗与神经精神疾病有关的症状。在本文中,我们描述了一系列中央吡啶相关的M4 PAM的合成,体外和体内表征,可以方便地用碳11作为PET示踪剂对其进行放射性标记,用于体内成像的变构结合位点。 M4受体。我们首先通过绘制小鼠大脑中的受体分布图并证实分子1仅在正构激动剂卡巴胆碱的存在下选择性结合至受体,证明了其可行性。通过竞争性结合亲和力测定和许多理化性质过滤器,几种相关化合物被鉴定为体内评估的候选物。然后将这些候选物用11C进行放射性标记,并在恒河猴中进行体内研究。这项研究最终导致了临床放射性示踪剂候选物[11C] MK-6884的发现。
