  • [<sup>18</sup>F]FPyKYNE, a fluoropyridine-based alkyne reagent designed for the fluorine-18 labelling of macromolecules using click chemistry
    作者:Bertrand Kuhnast、Françoise Hinnen、Bertrand Tavitian、Frédéric Dollé
    DOI:10.1002/jlcr.1533
    日期:2008.8
    FPyKYNE (2-fluoro-3-pent-4-yn-1-yloxypyridine) is a novel fluoropyridine-based structure, designed for the fluorine-18 labelling of macromolecules using copper-catalysed Huisgen 1,3-dipolar cycloaddition (click chemistry). FPyKYNE (non-labelled as reference), as well as the 2-bromo, 2-nitro and 2-trimethylammonium analogues (as precursors for labelling with fluorine-18), was synthesized in 44, 95, 60 and 41%, respectively, from commercially available 5-chloropent-1-yne and the appropriate 2-substituted-3-hydroxypyridines. [18F]FPyKYNE was synthesized in one single radiochemical step by reaction of no-carrier-added K[18F]F-Kryptofix®222 (DMSO, 165°C, 3–5 min) followed by C-18 SepPak cartridge pre-purification and finally semi-preparative HPLC purification on a Hewlett Packard SiO2 Zorbax® Rx-SIL. Using the 2-nitropyridine or the pyridin-2-yltrimethylammonium trifluoromethanesulphonate precursor for labelling (30 and 10 µmol, respectively), incorporation yields up to 90% were observed and 7.0–8.9 GBq (190–240 mCi) of [18F]FPyKYNE ([18F]-1) could be isolated within 60–70 min (HPLC purification included), starting from a 37.0 GBq (1.0 Ci) [18F]fluoride batch (overall decay-corrected and isolated yields: 30–35%).

    [18 F]FPyKYNE-c(RGDyK) was successfully synthesized by the Cu(I) catalyzed Huisgen 1,3-dipolar cycloaddition of alkynes to azides using [18 F]FPyKYNE as a prosthetic group in an overall radiochemical yield of 12%–18% (decay-corrected) and >99.5% chemical and radiochemical purities in 125 min including quality control. This simple, fully automated two-step, two-reactor approach consists of a quick and convenient purification of the prosthetic group using silica gel cartridges and its subsequent use for the labeling of the azido-c(RGDyK) peptide via click chemistry.
    [18F]FPyKYNE-c(RGDyK)由Cu(I)催化Huisgen 1,3-双极性环加成反应成功合成,其中炔烃以[18F]FPyKYNE作为辅助基团与叠氮化物反应,总放射化学收率为12%–18%(衰减校正),化学纯度和放射化学纯度均大于99.5%,整个过程(包括质量控制)耗时125分钟。这种简单、全自动的两步两反应器方法包括使用硅胶柱快速、方便地纯化辅助基团,以及随后通过点击化学将叠氮化物-c(RGDyK)肽进行标记。
  • Aryl Radical Enabled, Copper-Catalyzed Sonogashira-Type Cross-Coupling of Alkynes with Alkyl Iodides

    Despite the success of Sonogashira coupling for the synthesis of arylalkynes and conjugated enynes, the engagement of unactivated alkyl halides in such reactions remains historically challenging. We report herein a strategy that merges Cu-catalyzed alkyne transfer with the aryl radical activation of carbon–halide bonds to enable a general approach for the coupling of alkyl iodides with terminal alkynes
    尽管Sonogashira偶联在芳基炔和共轭烯炔的合成中取得了成功,但未活化的烷基卤化物在此类反应中的参与在历史上仍然具有挑战性。我们在此报告了一种将铜催化的炔烃转移与碳卤化物键的芳基自由基活化相结合的策略,以实现烷基碘与末端炔烃偶联的通用方法。这种前所未有的Sonogashira型交叉偶联反应可耐受多种官能团,并已应用于密集功能化药物的后期交叉偶联以及正电子发射断层扫描示踪剂的合成。
  • Synthesis and evaluation of the novel 2-[18F]fluoro-3-propoxy-triazole-pyridine-substituted losartan for imaging AT1 receptors

    The 2-[F-18]fluoro-3-pent-4-yn-1-yloxypyridine ([F-18]FPyKYNE) analog of the potent non-peptide angiotensin II type 1 receptor (AT(1)R) blocker losartan was produced via click chemistry linking [F-18]FPyKYNE to azide-modified tetrazole-protected losartan followed by TFA deprotection. Preliminary small animal imaging with positron emission tomography (PET) in rats displayed high uptake in the kidneys with good contrast to surrounding tissue. Rat metabolism displayed the presence of 23% unchanged tracer in plasma at 30 min. Upon co-administration with AT(1)R blocker candesartan (2.5, 5 and 10 mg/kg), a dose-dependent reduction (47-65%) in tracer uptake was observed in the kidney, while no difference was observed following AT(2)R blocker PD123,319 (5 mg/kg), indicating binding selectivity for AT(1)R over AT(2)R and potential for imaging AT(1)R using PET.
